Other programs include special anti-spies And antiviruses for cleaning advertising viruses. An example is the generally paid Malwarebytes Anti-Malware utility. However, some useful features can be used at no cost.

software is anti-spy– Great for detection and removal spyware. Thanks to it, unnecessary windows will not open in the browser, and clicks on dubious links will be block.

Scanner Malwarebytes can even find viruses that more popular programs cannot detect. However, unfortunately, it does not know how to treat them - all infected files are quarantined, deleted or left in place. Another minus - are not scanned zipped files. Therefore, its use as a main one is not recommended, but as an additional one it is just right.

You can scan the system online, for example using ESET Online Scanner. There are a lot of different antivirus programs, but most of them are not free and their effectiveness leaves much to be desired.

How to clear memory

After completing the treatment and removing viruses, you need to take care of cleaning the RAM.

To do this you need to run . It can be found in the button menu Start by right-clicking on it (or “ Ctrl+Alt+Del»).

When constantly working on the Internet or using unverified storage media, it often becomes necessary to clean your computer of viruses for free.

After downloading and installing the antivirus, you will need to run one of the proposed types of scans. Fast, usually takes a few minutes.

A full one, depending on the performance of the processor, the size of the hard drive and other parameters, can take half a day - however, at the same time you can perform other tasks on the computer.

Advice! If you suspect viruses in your system, you should always choose a full scan.

After many hours of scanning, a prompt will appear on the screen to disinfect or delete infected files.

If treatment fails, deletion will be the only possible way out of the situation - it is easier to install the application again than to leave malicious code in it and subsequently completely reinstall the system.

Kaspersky Anti-Virus

The next powerful anti-virus tool is the well-known domestic program.

By installing Kaspersky antivirus on your computer, you can immediately scan.

For further free support You will need to register and gain access to computer protection for a year.

The functionality of the free version is more than sufficient for one-time virus removal. And the controls are intuitive even for a user launching it for the first time.

AVZ

In order to get rid of malware using this free program, you will need to download it from the manufacturer's page, and then follow these steps:

• Launch antivirus;
• Go to menu "File" and choose "System Restore";
• Select all items and start their execution;
• Go to menu "Service"/"Process Manager";
• Remove processes that are not highlighted in green;
• Go to menu "File"/"Search Wizard";
• Clean up the operating system.

Other programs

With its help, unnecessary browser windows will stop opening and clicking on extraneous links.

There are also several options for checking your system online and getting rid of viruses without downloading programs.

One of them is ESET Online Scanner, the functions of which allow you to partially restore the functionality of the system.

Although its capabilities are much smaller compared to installed antiviruses.

There are several other good ones too free programs such as Avasta, and Microsoft Security Essentials.

However, there are several nuances when using them:

• Some of these antiviruses are free only for a certain period (for example, 1 year);
• Their effectiveness is less than that of the programs described above;
• Viruses are detected constantly, but if the system is already infected and malicious code is missed, most free antiviruses are no longer able to detect them.

Clearing memory

After viruses are detected or during a system scan, care should be taken to clear the computer’s memory, where there may also be unnecessary processes that negatively affect the performance of the system.

In order to detect them, you will need to launch the “Task Manager” (simultaneously pressing the “Ctrl+Alt+Del” keys).

After that, on the tab "Processes" You can see all currently running programs.

Some of these processes can be disabled.

Sometimes even a non-specialist can recognize them - malicious codes look like incomprehensible sets of characters (and even Chinese characters).

The main thing is not to accidentally close important processes, although most often the system simply will not allow this to happen.;

Type the command in the line "msconfig";

In the menu that appears on the tab, disable unnecessary applications (uncheck the boxes).

Basically, this list contains control programs for antiviruses, instant messengers, as well as some drivers.

The more applications it contains that the computer owner did not install, the greater the chance of infecting the system.

Additional actions

After detecting viruses and removing them, you should finally make sure that not a single malicious program remains either in the memory or on the hard drive.

To do this you should:

• Empty trash;
• Edit the registry. All installed programs are displayed in it in the section HKEY_CURRENT_USER/Software. Unnecessary ones are deleted using the “Delete” key.

Knowing how to clean your computer from viruses yourself, you should constantly carry out such cleanings at least 1-2 times a year.

You should also install a reliable antivirus and run it yourself from time to time to scan - real-time protection does not always protect the system, especially if the program is free.

Protect your computer from viruses

Signs of a computer infection

There are signs by which you can understand that a PC or laptop has become a victim of viruses. However, they may differ. Depending on the purpose of the malware software. But the general signs do not change.

With such a magnitude of disaster, only a complete reinstallation of the OS and formatting of the entire drive will help. And this is fraught with the loss of a huge amount of time and many important files (all of them).

Windows built-in utility window

Windows Defender can easily find and neutralize the most common viruses. Of course, it won't help much against Petya or WannaCry, but they are quite rare. Especially now.

Dr.Web Curelt

Dr.Web Curelt is an excellent computer virus scanner that is distributed free of charge if you do not use it for commercial purposes. Curelt is essentially a version of the famous Dr.Web antivirus. With this software you can periodically scan your PC for possible threats. I will say on my own behalf that out of many situations where computers were infected, I used this particular program, and it never let me down.

You can download it from the link. When Dr.Web Curelt is downloaded, run the downloaded file and select one of two types of computer scanning.

A quick scan will not take more than a few minutes (I recommend using this type of scan purely for PC prevention). A full scan will take much longer, since the processor will be stressed to the maximum. In principle, with any choice, you can go about your business on your computer while Dr.Web searches for malware.

I recommend: Perform a full scan when there is a suspicion of virus files.

When the program has completely scanned your computer, a window will appear asking you to cure or remove infected programs or files. If the files cannot be treated, then there is only one way out of the current problem: permanently delete them so that the infection does not go further.

HitmanPro

I couldn't even mention the wonderful virus scanner - HitmanPro. I found out about this merciless killer when I infected my computer back in 2013. The virus that “ate” all the resources of the video card, unfortunately, could not be found by either standard antiviruses or the scanners described above. After browsing the forums a bit, I came across this amazing piece of software. In a few minutes, thanks to Hitman, the virus was found and cleaned, after which the video card began to function as before. That's it, friends!

After that incident this program helps me out every day. Using HitmanPro together with the above-described Dr.Web Curelt antivirus, you can be sure that your PC is completely cleaned of malicious files. There is only one downside to Hitman - the program is paid, but if you need to clean your computer one time, you can register a 30-day trial version absolutely free. In addition, there is a hacked HitmanPro antivirus floating around the network, you just need to patch it exe file and use it repeatedly without spending a penny on a license. You can download the utility from the link

What to do after cleaning your computer from viruses

When the anti-virus system finds and removes all viruses, you need to finally make sure that not a single virus remains either on the hard drive or in the memory. To do this we do the following:
- empty the recycle bin and, if possible, temporary Windows files;
- delete unnecessary programs in the HKEY_CURRENT_USER/Software registry branch by pressing the “Delete” key (I have already described it in the corresponding article).

That's all! All the best!
