Mobile devices have made it much easier for people to access the Internet. From any tablet or phone you can go online and listen to music, watch a movie, read the latest news. The operating system for managing gadgets has evolved, become more complex and functional, and attackers took advantage of this by creating viruses for the phone. They steal personal data and can monitor user actions, so you should get rid of them immediately.

Your phone should be checked for viruses special programs, which are able to find a suspicious javascript file or apk file. There are several options for checking your gadget:

Usage mobile applications. Major antivirus software developers have created mobile versions of their programs. Some of them are paid, others have one-time trial versions, for example, Kaspersky, Dr.Web, Avast, etc. They work with all operating systems (Android, iOS, mobile windows), you just need to run them on your phone to check.
Treatment through personal computer or laptop. Computer security programs can scan hotel removable media, for example, a flash drive, CD, archives or phone. To do this, you need to connect the gadget via a wire to the PC and scan it through an antivirus.
Online verification services. Some resources offer to check your phone for viruses without installing a program, you just specify required file, which makes you suspicious, and they scan it. A significant disadvantage is that there are a lot of files on the smartphone and you will not be able to find the infected one quickly.

Mobile malware protection tools

The development and popularity of phones has led to the emergence of Trojans, worms and malicious JavaScript scripts. Previously, attackers could not steal personal data or access codes, but with operating systems approaching Windows in functionality, the “doors” were opened for viruses to penetrate. There are two main types of preventive protection for your gadget from pests:

Antivirus program. Most phones do not have pre-installed protection and the user has to buy or look for specialized software. As a rule, such programs provide comprehensive protection for your device against all types of malicious activities. automatic mode: worms, trojans, rootkit, data theft.

Firewall (firewall). This part of the protection does not detect existing viruses; the main task is to prevent them from entering the device. Paired with an antivirus, the firewall provides maximum protection phone.

How to check your phone for viruses through a computer

Malware strikes modern devices, it is impossible to find a worm on an old push-button device. Viruses were developed to steal your personal data, so their main task is to infiltrate the OS, disguise themselves and act unnoticed by the user. Previously, only Android mobile devices suffered from attacks, but now there is a threat to owners of Apple products as well. If the virus has entered the system kernel and the phone refuses to function, then all that remains is to check it through the computer.

Through an installed antivirus program

If you care about the security of your computer, then you should have an anti-malware program. It can also be used to clean your phone from viruses. To test the gadget, you will need a USB cable to connect and set the mode to “removable storage (like a flash drive). Then you will be able to run the check and scan the mobile files. For correct operation you need to set the USB debugging mode:

Open your phone settings.
Launch the “for developers” section, it may also be called “developer options” or “development”.
Activate the “USB Debugging” item.

Some phone models do not have such a section; it will need to be additionally activated. This is root mode, which, according to the creators of the mobile, is not needed by the average user, so it was hidden. You can open developer mode as follows:

Open Settings and tap About Phone.
Scroll to the "Build Number" line.
Click on it 5-6 times in a row.
A notification will appear telling you how many more times you need to press.
After the required number of clicks, the developer mode is activated.

Next, activate the storage mode so that the phone is detected by the computer as 2 disks (main memory and SD card, if available). Next, you just need to right-click, select scan or scan from the list using the software that you have installed. The antivirus is able to scan all the data on your mobile phone and identify potentially dangerous and malicious files.

Using Windows Defender

Computers that run Windows OS have special utility for protection against viruses. It comes complete with the installer and performs the functions of a standard antivirus. When connecting the phone in the manner described above, so that it is detected as a removable storage device. Next, the algorithm of actions is as follows:

Connect via USB cord your gadget.
Before checking, it is recommended to delete the entire memory cache from the browser you are using. This is done through the “Applications” tab in the phone settings.
Open Explorer, right-click on the drive that corresponds to the connected mobile phone.
A context menu will appear, select “Scan”.
You can run the scan from the notification area in the lower left corner. Click on the " Windows Defender" and run "Special Scan". Then select the drive that matches your phone.

Checking your smartphone for viruses in the mobile application

Malware often behaves secretly and does not completely break the operation of the gadget. This allows you to check using special application for phone. Major antivirus developers have released utilities for installation on mobile devices. There are free, stripped-down versions that are given for a time or have no full functionality. You can buy a full-fledged antivirus with all the functions. It protects your phone in real time and helps you check files if you suspect an infection.

Java phone

There are very few such devices left, but if you are the owner of such a mobile device, then a common variant of infection is infiltration of a Java application. Your phone tries to send strange SMS when launching applications, makes unauthorized phone calls, after which money is withdrawn from the account. Structure Java systems very simple, so there are no special antiviruses for it. Removal suspicious file carried out manually.

A device with an operating system based on the Symbian platform

This operating system was actively used for the first smartphones until 2010. In its place came a more efficient, fast-acting and multifunctional Android OS. There is currently no support or further development for Symbian. If you have an old device on this operating system, then you can check and protect your device using the following programs:

Defenx Mobile Security. This is a whole set of programs that protects your smartphone from malicious code: anti-spam, anti-theft, anti-virus.
Dr. Web Antivirus. Mobile version of the famous antivirus. On at the moment It is considered the most powerful for this OS, certified by the Russian Ministry of Defense.
Kaspersky. The application is designed specifically for switches. Provides protection against all types of malicious activities.

Android smartphone

Long time viruses for operating system Android did not exist, but the widespread popularization of the OS attracted hackers. The penetration of Trojans, which add additional advertisements to games, browsers, and applications, and redirect to third-party sites, has become a common phenomenon.

Phones and tablets running Android OS are in many ways similar to computers running on Windows based. Both systems have many open components, which allows you to customize them for your convenience. At the same time, this feature opens the way for malware – viruses. These are mini-programs that steal data, block functions, and disable devices. For this reason, it is necessary to check your system for viruses from time to time. In this article, we will find out how to check your Android device for viruses, and most importantly, how to “cure” it and secure it.

How do you know if your device is infected?

So, first you need to find out if there is a virus on your device. Sometimes this is noticeable right away. Incomprehensible activity appears, errors in the system, money leaks from the SIM card, and much more. It happens that it is not so easy to find out if there is a virus on an Android smartphone. They are often quiet, not showing themselves in any way most of the time. In this case, you will have to use an antivirus program that will assess the state of the system, identify malware and try to eliminate it.

What viruses are there on Android?

Malicious programs are divided into specific categories based on their functionality and behavior. Among these categories, the following malware variants are distinguished:

Trojan is a program that sneaks into the root of the operating system and quietly collects personal information The person who owns the device sometimes calls toll-free numbers that were inserted into it by the attacker who created the virus.
A virus that downloads fraudulent applications to a smartphone or tablet- This is another type of virus that creates quite a few problems for people. He intentionally downloads programs from the Internet and creates his own files and directories in the system. He can get superuser rights and start showing the user advertising windows, slow down the system, change various parameters, creating a real hell for the user, in which he will have to live until the malicious program is removed.
com.android.systemUI– another component that can provoke the launch of a Trojan hiding behind a free game or application downloaded from the Internet, bypassing the Play Market. It works like the previous virus, introducing intrusive ad blocks into the system.
Ransomware malware– a virus whose use was actively practiced in Windows times XP. Essentially, this is a pop-up window that notifies you that your phone is blocked by some service from above and in order to gain access to the phone, you need to pay a symbolic amount. Naturally, if you pay, no one will return anything to you. The only method is to find and remove software that interferes with operation. Reflashing the device and resetting it to factory settings also helps.

Removing dangerous programs using applications from the Play Market

Now we have come to the point of removing malware. You can clean Android from viruses using special software from the app store Google Play. There are at least three popular antivirus for Android phones, which do an excellent job of destroying malware that interferes with the system.

Avast

The first one on our list, it is quite effective and absolutely free. This program is known to many, since it is the only high-quality and free antivirus for Windows. On Android it works in a similar way. It protects the phone from viruses, searches for them and notifies users when new ones appear. Scans all downloaded files for malicious code. Checks everything wireless networks, to which your device connects. Cleans the memory and system of all digital garbage such as caches and frozen programs. Overall a great choice to start with.

AVG

Another utility to protect your gadgets. It scans the device in real time, constantly monitoring running processes and identifying inconsistencies in them. Of course, AVG looks for Trojans in downloaded files and applications. The program has several more useful options. For example, it will help you find your phone if you have lost it. Closes programs that slow down the system and cause problems in its operation. Moreover, using the program you can protect individual programs from losing confidential data (set a password, install additional encryption).

ESET

The NOD 32 antivirus series has a very positive reputation. These applications have served many computer users faithfully. Now they do the same on Android. NOD 32 is always in working condition and interrupts any attempts by the antivirus to penetrate the system and run in it. The program works with SMS mailings and unwanted calls, blocking them. Using the application, you can not only check each application for viruses, but also give them certain rights to connect to the Internet. And NOD 32 also protects email and browser, preventing phishing links (these are links to fake sites where attackers, pretending to be official resources, steal logins and passwords, which they then use on original sites) to reach you.

How to check Android phone via computer

If it is not possible to check your device for Trojans using an antivirus on your phone or tablet, then you can try checking Android for viruses using a computer.

To do this, you need to do the following:

Go to device settings (if this is still possible);
Find the submenu “For Developers”;
Enable USB Debugging features;
Enable any antivirus that is installed on your computer and start the scanning process.

Unfortunately, this method Android checks it rarely helps to detect the presence of viruses. The fact is that in this way you can only check the phone’s storage, but the system itself, and especially its root part, cannot be checked. In addition, many antiviruses for computers “know” only malware for desktop systems, and they are not familiar with mobile malware.

Conclusion

So we figured out how to check an Android phone for viruses. Moreover, now you can save your gadget. Of course, the above is not the most full list antivirus programs, and you can choose something else for yourself. However, these are actually working utilities that can save your data and also keep your devices in a stable state. It's worth remembering that best way protect your phone or tablet from viruses - stop visiting unverified sites and downloading programs from unofficial sources. One day, when you decide to download a pirated program, you may find yourself in big trouble.

If you are thinking about how to check your phone for viruses through a computer and doubt the reliability of this method, then you can cast aside all doubts. Such scanning is quite effective, since the database of virus signatures in the antivirus on the computer is constantly updated, adding data about new malicious codes to its archive. In addition, you can not only scan your smartphone, but also clean it of hidden viruses.

Let's get straight to the main part of our discussion today. So, first of all, we will need to decide what type of phone you have. The most popular smartphones today are running the following operating systems: Android, iOS, Windows Phone, Symbian. Since iOS and Windows Phone are positioned as closed operating systems, therefore, a virus cannot work on them (even if it exists) and there is no point in checking for malicious data. The situation is completely different with the remaining operating systems, which are most susceptible to virus attacks due to the openness of its system.

Android and Symbian

Where can you “catch” the virus?

As you know, Android occupies a large share of the mobile phone and smartphone market. This is not surprising, since the system can be used by almost any mobile equipment manufacturer. But for this opportunity Google I had to pay a considerable price - an open operating system. The same is true for Symbian, despite the fact that the OS is installed almost exclusively on Nokia devices.

What does open operating system mean? This means that you have full access not only to regular folders on the device (the role of Explorer), but also to system services. And if you have this access, it means that malicious code can even penetrate the system. You should also understand that a virus can harm a smartphone not only by penetrating system directories. It can do the same if you download from the wrong resource, even a simple picture to the folder on the Images flash drive.

Where can you actually get a virus on your smartphone? Naturally, on the Internet. But this is half the problem: malicious code or programs can reach you through the standard Play Market application store. However, it is worth noting that those users who do not look carefully at the downloaded product are subject to attack. For example, you can download a game from some unknown developer with a dubious level of trust (judging by the reviews on the application page). But you must understand that you cannot download it. This can lead to unpleasant consequences. When working in the Play Market you just need to be a little careful and then there will be no troubles with virus programs you are not afraid.

With the Internet, everything is much more complicated, because it is almost impossible to control every site and download. Here your smartphone is at risk in the same way as a personal computer. It is especially not recommended to download games and applications from third-party resources (use only Play Market). Hence, it is recommended to install antivirus software on your phone. But what to do if the malicious code has already taken root and you don’t have the opportunity to download such software from the Play Market? Then you will need to scan your smartphone for viruses through your computer.

Checking Android and Symbian smartphones using a computer

All you need to work is the smartphone itself and a cable to connect via USB port. It comes complete with the phone and is often a charging cord without a power supply (a unit for connecting to an outlet). So, your actions:

Connect your smartphone to your computer and select the connection type “Storage Mode” (the name may vary).
Open Anti-Virus on your computer and find “Custom Scan”, that is, so that you can choose the folder that will undergo the mentioned procedure.
Now you need to select the smartphone folders and wait for the scanning to finish.
After this, the Anti-Virus may offer some solution options (for example, remove the virus or clean it). Here it is important to see which files and folders are infected with malicious code. Because if the program cannot clear these codes, then you will have to manually find these files and delete them.
After removal and treatment, perform the scanning procedure again. If there are no more viruses, then the job is done.

Let's sum it up

Please note that the computer may display two folders associated with the computer: one system, and the other from the flash drive. Both directories should be checked. Then you can easily scan and clean your smartphone from viruses using a computer. We hope that everything worked out for you and there are no problems with your phone. From now on, be more careful and attentive when working on the Internet. You can tell in the comments where and what kind of virus you introduced into your device to warn other people. Have a nice day, dear friends!

Checking your phone for viruses - is it difficult?

Modern smartphones have quite acceptable technical characteristics and rich functionality: support for Wi-Fi, Bluetooth, 4G radio modules, video communication, as well as the presence of a variety of useful or simply

entertainment applications. A smartphone that combines compactness and is loaded with various bells and whistles may well become a worthy replacement for larger personal PCs. However, smartphones also have a significant disadvantage - the presence of an operating system, which implies the possibility of infection with viruses. This applies to phones based on open and shareware mobile operating systems: Android, BlackBerry OS, Symbian, etc. Modern mobile viruses, penetrating into the smartphone along with installed applications, are divided into 2 categories:

ransomware that sends messages to paid numbers without the knowledge of the owner of the device;
intelligence programs that collect all confidential information- numbers bank cards, passwords, list of completed transactions, etc. - and sending it to its creator.

How to check your phone for viruses using special mobile software?

From the above it is clear why it is so important to take your information security. In particular, you need to have an idea of how to check your phone for viruses at the slightest suspicion that something is wrong.

The antivirus can be downloaded and installed in a special application store or through the "Downloads" menu. After installing the program, you can immediately start scanning, and also, if desired, set a schedule in the system settings automatic checks. As a rule, a high-quality mobile antivirus provides almost one hundred percent protection for your device.

How to check your phone for viruses via a computer?

If you are unable to access the Internet from your mobile device, don't worry - there is another way to scan your phone system for

presence of malware - using a computer. To connect your smartphone to your PC, you will need a USB cable. After the connection is established, your mobile phone will appear as removable disk, which can be scanned using a computer antivirus. However, before you check your phone for viruses in this way, just in case, create backup copy data in order to avoid loss of valuable information. But this method of getting rid of an infection does not always help, since the virus can often “sit” in system root folders that are not displayed when connected to a computer. How to check your phone for viruses in this case? In such a situation, you can download the antivirus file (corresponding extension) to hard drive computer, and from there copy it to the smartphone’s memory, for example, to the Download folder. After this, you should disconnect the mobile device from the cable and use the file manager to go to the folder where you saved it. installation file, and run it from there. Your phone is now protected. The main thing is to update virus databases on time.

Every year for the Android OS the number of malicious applications and files. And scammers and hackers are coming up with more sophisticated ways to steal money and personal information from your phone. Therefore, it is important to prepare and know how to check your Android for viruses.

Ways to check your Android phone for viruses

There are four methods for diagnosing a mobile device for viruses:

Mobile antiviruses.
Using a computer.
Online check.
Google Play Protect.

Method 1: Mobile antiviruses

Checking with mobile antiviruses is the simplest method available to everyone Android owner phone or tablet and does not require a PC. For checking, Android applications are used that work on the same principle as on desktop versions of the OS. Mobile antiviruses allow you to detect and remove installed applications with malicious code, report existing vulnerabilities, unwanted actions or files.

Instructions for checking:

Download and install an antivirus application. To do this, follow the link where popular and popular ones are collected antivirus utilities. Or go to the store Google applications Play and specify “antivirus” in the search.
Launch an antivirus program and scan for threats. To do this, you will need to update the signatures - the database.
If necessary, configure the utility for in-depth analysis. This will increase the scan time but increase the likelihood of detecting threats.
Wait for the scan to finish, make a decision if viruses are detected: remove, cure, quarantine, etc.

Important!

Before installing a new utility, you must uninstall the previous program to avoid conflicts in the system.

Most antiviruses are distributed under a paid license, and developers often provide trial version for 1-4 weeks free of charge. Don't neglect trial license, as this will allow you to take full advantage of the antivirus.

Before installing an antivirus, it is advisable to visit an independent organization AV-TEST, specializing in testing security programs.

When downloading an antivirus program via Google Play, it is worth comparing the name of the utility and the developer. Often, attackers download fake applications with a similar name.

Below is an overview and comparison of popular antivirus applications.

Method 2: Using a computer

The method is similar to the previous one, only instead of mobile antivirus, to check your Android phone for viruses, use the desktop version designed for PC. This type of diagnostic allows you to identify hidden threats that have been missed mobile version. Detect unwanted files, as well as check programs downloaded not from official application stores.

Instructions on how to check an Android phone for viruses via a computer:

You need to connect the device to the computer where you installed antivirus program. Otherwise, you need to download and install the utility. To do this, use only official resources.
In the phone connection settings, specify MTP (Media Transfer Protocol). This is necessary to display the device memory in the form of removable disks.

Often Android system prompts you to select the connection type when pairing the device with the PC. If this does not happen, you need to activate the item manually. This is usually done in the “memory” item, settings section, sometimes in the “for developers” item. To get to the latter, you need to click on the build number 7 times in the “about phone” section.

After displaying the internal and/or external memory, you need to scan one by one. To do this, highlight the disk, right-click and select context menu item related to scanning.
Wait for the operation to complete and delete any malicious files found.

Method 3: Online check

Many users prefer to download programs from third-party or pirated application stores. This often leads to the installation of a virus under the guise of normal program. Therefore, before installation, it is rational to check the file with a cloud antivirus or online scanner. The service will analyze the contents of the installation apk file and compare the data with known virus databases. Such services will come in handy for users who do not have access to a computer or who do not want to use mobile antiviruses.

Instructions for online verification:

We find a service to check. Let's use as an example free service virustotal .
Download the application you like. For example, we use one of the antiviruses in our catalog - G Data Internet Security Light, available here.
On the virustotal page, “file” tab, indicate the location of the installation application. This action is available from both a PC and a mobile device.
If the file exceeds 128 MB in size, you should indicate a direct link to the application in the adjacent “URL address” tab.
We wait for the results of the analysis, make sure that the application is safe, and then install it on the mobile device.

Method 4: Google Play Protect

Android OS has built-in anti-malware protection – Google Play Protect. This is a passive antivirus, the quality of which leaves much to be desired, as confirmed by the results
