How to clean your computer from viruses?

Why do viruses appear on the computer?

 

The occurrence of viruses can occur completely unnoticed, for example, by clicking on a malicious link, opening a spam email in an email or via a USB drive, and accordingly, a logical question arises: how to clean a laptop from a virus?

It is not in vain that a computer virus has such a name, because its main goal is to infect and take root in the codes of programs and files, after which, as a rule, the entire system is affected without the possibility of recovery.

 

What happens to a laptop infected with viruses?

 

The main signs by which you can determine the possible effect of the virus is to pay attention to the following elements:

 

- slow down the device;

- the appearance of programs that you did not install;

- replacement of the search engine without your consent;

- tabs with ads that open on their own;

- programs often close showing an error;

- failure of the entire system: the appearance of errors on a blue screen background.

 

Pay attention to such moments, because not only the operation of your device, but the confidentiality of file storage depends on it. Below we will tell you in detail how to clean a laptop from a virus.

 

Search for viruses on the computer

 

If it seems to you that there is a virus on your device, check your antivirus system, it may have warned you about some suspicious manipulations on your computer.

However, often, the “anti-virus” does not react at all to malicious attacks. Why is this happening? Not all protection programs, unfortunately, can expose the attack of serious viruses. But do not rush to reinstall the operating system. There are various ways to avoid this.

Cleaning a computer from viruses for the Windows operating system

 

1. Scanning startup items.

 

Questionable applications can change user settings and thereby harm your computer, so in this case, you need to check the programs that automatically start when the system boots.

 

1. Reboot the OS in safe mode (when starting the PC, press the F8 button until the system boots up).

2. When the system is loaded, go to the start menu and type msconfig in the search box.

3. In the “System Configuration” menu, select the “Startup” tab.

4. The system will prompt you to open the “Task Manager”, where you can review all the programs that are running on your device.

5. Select unnecessary or suspicious programs and click "Turn off".

 

Also, to disable startup programs when you turn on your computer, go to "Settings" - "Startup". Disable unnecessary programs using the toggle switch.

 

2. Uninstall programs.

 

Do the following:

 

- go to the “Start” menu - “Control Panel”;

- then select the "Programs" - "Uninstall programs" window.

 

Review all installed programs on the computer. If you notice suspicious applications and know for sure that they are not related to the operation of the operating system, remove them.

 

3. Removing the virus from the Windows registry.

 

To check and edit the registry, you must:

 

- go to the Start menu and type regedit in the search bar;

- in the "Editor" of the registry, select the "Edit" tab and click "Find".

 

You must enter the name of the suspicious software. If the system recognizes it, you can delete the data.

 

4. Deleting temporary files.

 

Sometimes, viruses are found along with “digital junk”. You also need to get rid of it.

 

1. Go to "My Computer", select "Local Disk C" and right-click on "Properties".

2. Select the General tab and the Disk Cleanup option.

 

After analysis, the system will offer a list of temporary files that you can delete.

 

5. Correction of browser extensions and settings.

 

If you notice suspicious "behavior" of your computer when you start your browser, check its settings and extensions.

 

Instructions on the example of the Google Chrome browser:

- log into the browser;

- enter chrome://extensions/ in the address bar.

 

Here you can see all the extensions and settings that have been installed in the browser. If there are unnecessary or suspicious - delete.

 

How to make sure that there are no more viruses left on the computer?

 

In this case, to clean your computer from viruses, you can use third-party services. After scanning the device, you can make sure that there are no more viruses on the device.

Before proceeding to the selection of an antivirus program, it is worth noting that before starting the service, you need to transfer the system to safe mode (when starting the PC, press the F8 button until the system boots up).

In conclusion, I would like to note a few important points that can further protect your device from computer viruses.

In order to regularly clean your computer from viruses, you must install an antivirus program immediately upon purchase of the device. It is important to install licensed software programs only from the official websites of developers. When downloading different programs, do not agree to download additional files.
