If the antivirus installed on your computer does not detect anything suspicious, but the symptoms are obvious (freezes, incomprehensible running processes, appearing autorun.inf on flash drives, etc.), a “one-time antivirus” is necessary. It's easy to use - just download from the link and run it. In this case, during the scan, it is advisable to disable the antivirus that is installed on a permanent basis.

Advantages of disposable antiviruses

1. Free. For home use Almost all one-time antiviruses are free.

Flaws

1. They are not capable of protecting your computer all the time (there is no module for permanent protection) and there is no update of anti-virus databases.

2. You have to download it again every time so that such an antivirus detects new viruses.

Dr.Web CureIt!

Dr.Web CureIt!- a good one-time antivirus. Knows how to fight running viruses (does not allow itself to be killed during scanning).

HerdProtect

An online antivirus that scans all computer files using 68 antivirus databases. I explained how to use it in a separate article.

This good option, if unlimited Internet is connected.

Minus: does not know how to treat infected files.

Plus: You don’t need to download it again to check, the databases are always fresh.

Kaspersky Virus Removal Tool

ESET Online Scanner

Plus Online scanner- no need to worry about downloading new versions with fresh databases. Just open the link or run esetsmartinstaller_rus.exe, the antivirus will start, update and scan your computer for viruses.

Norton Security Scan

Norton Security Scan - another one-time antivirus. You can download the interface in English, but simple.

Checks hard drives very quickly. Requires an Internet connection, just like Eset Online Scanner.

When you first start it, it creates a shortcut to itself, which is strange.

In general, it is better not to use it, since viruses common in Russia enter its database a little late. The newest winlockers (ransomware banners) are unlikely to be detected.

AVZ or Zaitsev Antivirus

Powerful antivirus utility (not a full-fledged antivirus!) for advanced users. There are not a sea of ​​functions, but a whole ocean.

Supports updating anti-virus databases from the Internet. Unlike disposable antiviruses, it cannot treat infected *. exe files. It's more of an "anti-spyware" with many unique additional functions. I will quote the words of the author AVZ: “ The utility is a direct analogue Trojan programs Hunter and LavaSoft Ad-aware 6. The primary task of the program is to remove AdWare, SpyWare and Trojans.» The archive with the program contains help on all functions; it must be read carefully before the first launch.

If you are tired of installing and uninstalling antiviruses, downloading antivirus databases and activating keys, turn to online antiviruses. Checking files for viruses without installation is a completely worthy alternative to traditional scanners.

We have selected half a dozen reliable, free and effective antivirus scanners, which work online - that is, through a browser. This way you can find out if there is a virus on your phone without downloading third-party programs.

Which web service should you choose for a one-time check? Is online antivirus suitable for Android? Read about all this in our review.

List of online antiviruses:

Powerful online scanner Doctor Web

This service designed to check security references. You paste a link to a suspicious site into a special text field, and Doctor Web scans the attached files on the html page, examining whether there is malicious code. As a rule, a virus threat on online resources is hidden in javascript files. If scripts are contained in the database of malicious sites or the site redirects to another resource, Doctor Web Online will notify you about this.

As you can see, the service is very minimalistic, there is only a web-based antivirus shell, which is not very convenient. It would be good if the Doctor Web service acquired, say, an Android application for online checking or, ideally, a browser add-on. On at the moment We wouldn't recommend an online version of antivirus for use on a phone.

Tip of the day. By the way, if you need a good free antivirus to check your computer (or memory card/flash drive) for viruses, without downloading additional applications, we advise. It uses the current databases of the desktop version of Doctor Web, while the functional part is reduced to a minimum.

ESET Online Scanner - online file scan for viruses

The antivirus scanning service from ESET is a comprehensive and effective antivirus. It works from a browser, scanning files and does not require installation on a computer.

Unlike desktop ESET versions Nod, this web antivirus is free to use. Don't think that it makes no sense to require a full-fledged scanner from a web application. According to the creators, the online antivirus successfully copes with Trojans, the latest viruses, worms, phishing threats.

The user can select files on the computer disk to scan, specify memory areas, etc. Moreover, to run an online check, you do not need to have administrator rights.

Upon completion ESET search Online Scanner offers to remove detected viruses or quarantine infected files.

In general, cleaning viruses using the web ESET antivirus Online Scanner makes sense in many cases. In particular, if you want to scan someone else's computer, check the flash drive for malicious files online, but you do not have the rights (or desire) to install applications.

VirusTotal - total online scanning of files for viruses

VirusTotal is another one free service, which checks for viruses online. It scans the contents of files and code of sites on the Internet. VirusTotal scans any suspicious content for worms, malware, Trojans and other types of pests and viral threats.

Video on how to use the service:

VirusTotal also allows you to search for threats in comments that users post on files and URLs, check passive DNS data, and retrieve threat information related to domains and IP addresses.

VirusTotal stores all analyzes in its database. This allows users to search for reports with MD5, SHA1, SHA256 data. Search results returns the last scan performed on the resource you are interested in.

Kaspersky Online Scanner (VirusDesk)

Online service from the creators. Checks files and links on the Internet and does not require installation additional modules. When you download a file, Kaspersky scans it across its databases for existing threats and displays the result. In this case, md5, SHA1 and SHA256 hashes are checked. All databases are regularly updated, as evidenced by the corresponding inscription above the file upload field.

The result of the scan may be negative, in which case VirusDesk issues a status: the file is infected or suspicious.

Important! Unlike conventional antiviruses, you can only scan a file for viruses, and you cannot quarantine or automatically delete it - this can only be done manually.

This online antivirus will do and to check your phone for viruses. You can upload files up to 50 MB; batch mode is not supported. The scanner does not remove viruses - the user must perform this action independently. At the same time, to perform a single scan Kaspersky Virus Desk it could become like this one-time antivirus, which is also good.

VirSCAN - online antivirus for Android

Using the VirSCAN.org service, it is possible to check Android for viruses online, as well as online scanning files for malicious code.

For example, you can send apk applications or other files for verification (the size should not exceed 20 MB). These can be zip and rar archives or with password protection(only the passwords “infected” and “virus” can be set).

The main and most significant feature of the VirSCAN online antivirus is a huge database of regularly updated scanners, including kaspersky, avg, drweb, symantec and others. Among other things, VirSCAN checks MD5 and SHA1 hashes against its databases.

The disadvantage of this online checking mechanism is slow speed work, the absence of any settings (that would speed up the process) and the lack of scanning options: only downloading single files for virus scanning is allowed.

AVC UnDroid – service for checking apk files

The free online service AVC UnDroid is designed to search for viruses in the contents of apk files. It uses scanning engines such as Buster Sandbox Analyzer, ssdeep and APKTool.

To check an apk for viruses, click the Select APK... button and download the installer file to check on your phone. AVC UnDroid supports data up to 7 MB in size, which is enough for most tasks.

Uploaded files are analyzed inside AVC UnDroid, after which the user receives a detailed scan report - file hashes, security rating and additional information.

Other data types are not supported and you can only upload one file at a time.

For convenience, you can register. This opens up access to statistics and comments, increases the limit on downloaded files and increases priority.
