• Cleaning your computer from viruses. How to clean your computer from viruses for free and easily? The most effective ways

    Viral infection computer system- the situation is not the most pleasant, especially considering that some modern threats are capable of disabling the operating system and destroying or stealing the user’s personal data. Next, it is proposed to learn how to clean a computer infected with a virus using several options and the tools used accordingly. Looking ahead a little, it should be noted that you should not completely rely on modern antivirus programs, since in some cases manual intervention by the user may be required to remove or neutralize the virus threat.

    How to clean your computer from viruses yourself: tools and steps to use

    Despite a fairly wide variety of protective equipment and tools in the form of specially developed programs, sometimes many of them turn out to be completely powerless against certain types of threats. In this case, we are talking about the fact that cleaning your computer from viruses using conventional means can be problematic only because some types of threats are disguised as trusted applications, supposedly representing a partner software, installed by the user in parallel with the main application. In addition, many such applets also have certificates of authenticity confirming safety, and even digital signatures. In other words, standard or portable scanners may not detect such viruses. This applies to both an immediate threat and potentially unsafe or unnecessary software.

    In this regard, several standard methods and tools can be proposed:

    • standard anti-virus modules;
    • portable treatment programs;
    • boot disk utilities;
    • manual removal viruses (most often applied to browser hijackers);
    • drastic actions.

    How to clean your computer from viruses in Windows 7 or another OS using standard means?

    Most users do the absolutely right thing, not trusting the security tools built into Windows systems, but installing anti-virus packages from third-party developers, which in their own way functionality head and shoulders above those developed by Microsoft. Why is this so? Yes, only because the company itself is positioned precisely as a developer of operating systems and some other software products, and certainly not a manufacturer of software computer security.

    Thus, the easiest way to prevent viruses is by calling the on-demand scan function. In this case, it is advisable to use the in-depth scan mode, otherwise complete cleaning will not work.

    Portable apps and online scanners

    Unfortunately, many desktop antivirus programs can quite often miss threats, especially those that are embedded in Internet browsers in the form of add-ons or additional extensions. In this case, you can clean your computer from viruses without using standard modules (which have already missed the threat) using portable programs, among which you can find antiviruses, antispyware, and anti-advertising tools.

    The most well-known and effective means for all occasions can be called parallel programs like Dr. Web CureIt!, KVRT and AdwCleaner. For them, one of the main conditions for fully functional operation is updating the anti-virus database at every start. Just like in stationary programs, you can select the objects to be scanned, including boot and hidden areas of hard drives and any removable media, yourself. The advantage of using them is that they can be “clean”, while even a standard antivirus can be infected.

    Disk Utilities

    If we talk about how to clean a computer with Windows 10 on board (or with a lower version of the system) from viruses, when the above methods did not produce results (it is known for sure that there is a virus, but it was not found, the threat cannot be removed or neutralized, etc.) . d.), as one of the most powerful tools I can recommend programs like Kaspersky Rescue Disk.

    Their peculiarity is that when recording on removable media are saved on it special files independent bootloader. In other words, by setting the device with the program first to boot through the BIOS, you can launch the antivirus itself and scan the computer before Windows starts. It is worth noting that such applications are capable of detecting viruses that choose their habitat RAM(neither regular nor portable programs they may not even dream of this).

    Principles of manual cleaning

    Finally, to remove some types of threats that are only partially classified as viruses (group unwanted programs Hijackers), you can also use manual removal.

    As a rule, such software applets (with rare exceptions) are not particularly disguised in the system, and you can find their processes in the same “Task Manager” or delete the main application files through the programs and components section in the standard “Control Panel”.

    Approximate procedure

    Let's try to consider exactly what actions will be needed in order to clean the computer from viruses that the user has identified in the system on his own (for example, by viewing processes in the Task Manager and determining the location of the virus files and folders on the hard drive).

    So the order could be like this:

  • completion viral processes in the “Task Manager” with a preliminary determination of where the threat files are saved on disk;
  • disabling virus applets in startup (if any) through the system configurator (msconfig);
  • standard deletion the main components of the virus through the programs section and Windows components;
  • search by virus name and remove residues in system registry(regedit);
  • search and delete residual files and folders in Explorer (or delete objects from a previously defined location);
  • for browsers - checking the program shortcut (the path to the executable file must end only EXE extension without any additional additions);
  • Note: to simplify all the steps described above, you can use the uninstaller utility iObit Uninstaller (the program allows you to clean your computer from viruses in no time, and it finds and removes remnants of applications automatically). If you still use manual removal, sometimes you first need to delete the registry keys, and only then proceed to uninstall the main program.

    Complete cleaning using drastic methods

    As for how to completely clean your computer of viruses, there are two options: either restore Windows to a time when there was no virus in the system, or format the hard drive (quick or full).

    Keep in mind that after quick formatting It is possible to restore files, but this equally applies to objects associated with deleted virus threats.

    Instead of an afterword

    In general, if we sum it up, it is not difficult to realize that there is nothing particularly difficult even in manually cleaning the system from all kinds of virus threats. By the way, the above procedure for independently neutralizing, say, browser hijackers is almost always used and is a universal course of action if no anti-virus utilities detect the embedded threat or cannot remove it.

    However, it is worth paying special attention to the use of uninstaller programs. They are good because they remove applications, find keys with files and folders, and allow you to uninstall add-ons or various additional panels of any browser. Even applets built into the operating system will not be difficult to remove with their help.

    Almost all antivirus software operates in automatic mode and reliably protects your laptop from viruses. However, there is no perfect protection, so some malware can make its way inside the OS, causing stuttering and other malfunctions in the PC. In this case, you have to clean the system yourself. Let's look at how to clean a laptop from viruses if the antivirus did not cope with its task.

    Methods for cleaning the operating system from viruses

    To completely remove malware from the system and rid your laptop of slowdowns, an antivirus program alone may not be enough. In such cases, it is recommended to use complex treatment of PC, including:

    • removing a virus from the Windows registry.

    Cleaning your system with CCleaner

    During operation, the operating system creates a lot of intermediate files, which over time not only clog the storage medium, but also slow down the PC.

    Solving problems with browsers

    • sometimes when entering the Internet, the user ends up not on the main page, but on another site - most often a phishing site or advertising some services;
    • When the browser is launched, a third-party plugin may be installed that changes search engine, home page and online settings.

    You can solve the problem manually by checking your browser shortcuts. But the best way to do this is with utilities such as Shortcut Scanner. The free application checks the logical and external drives for the presence of unwanted programs, identifying suspicious or broken shortcuts.

    The advantage of using this tool is free distribution and work on any modern systems Windows (from XP to 10), the disadvantage is the lack of a Russian version.

    Other companies also produce similar functional and free utilities. Moreover, for different browsers and with a wide range of possibilities. Some programs also provide effective protection in real time - however, most of them have a paid option for this.

    Conclusions

    Using applications that remove unwanted software does not eliminate the need to install antivirus software. Each program performs its own tasks. Antivirus utilities protect the system almost constantly and prevent infection of system files.

    And applications to fix existing problems are needed mainly after the antivirus has proven ineffective. Using two options at once - installed and periodically launched utilities - will ensure maximum protection efficiency. Although in order for the computer to be even more secure, it is advisable:

    • follow the recommendations of anti-virus utilities that issue warnings when entering suspicious resources;
    • scan with antivirus software downloaded or recorded from external media files whose origin is unknown (for example, downloaded not from the official website, but from a third-party web page);
    • set in antivirus settings automatic update virus databases and run the application manually at least once a week.

    Preventing your computer from becoming infected with viruses and other types of malicious code will reduce the likelihood of problems occurring. Although neither Curelt! nor even a paid antivirus provide 100% protection.
