So you have contracted a virus that has taken over your computer and you can’t even start to try to solve the problem. Signs of a PC potentially infected with malware: slower than normal performance, the recent appearance of many pop-up windows and other strange problems. It is possible that your system has been infected with a virus, spyware or other malicious virus – even if you have installed an antivirus program. Yes, unusual behavior is sometimes the result of hardware problems, but it is best to remove malware first if your PC is performing well.

One of the most common questions asked by readers infected with computer viruses is: “How can I get rid of a virus if I can’t even start a Windows antivirus scan? Fortunately, there are a number of free and relatively easy-to-use tools that can help you.

Almost everyone will experience some kind of malware infection during their computer life, but if you know what to do, you can remove a virus from your PC or laptop yourself.

To remove a virus from your laptop or PC:

Use the safe mode

If you have a very persistent malicious infection, you may need to scan for malware outside your normal Windows system. To do this, you must start Windows in safe mode so that it does not load normal boot applications – including, we hope, this malicious software. Run a Windows Defender scan and then a Malwarebytes scan in safe mode, and you may be more likely than usual to remove malware.

To start in safe mode on Windows 8 or 10, hold down the Shift key while clicking Restart, then select Troubleshooting > Advanced Options > Windows Start Settings > Restart > Safe Mode. On Windows 7, press the F8 key while your computer is booting, and you will see a boot options menu where you can select the safe mode.

Delete your temporary files.

Computers have certainly made our lives easier. But it is also true that we are dealing with viruses, malware, worms, Trojans and more. They can infect your computer at any time, and they can be torture to get rid of them.

Determination of malware load points

Malware, like any other active program, must be loaded to cause damage. Once you have secure access to the infected drive, first check the general starting points to detect any signs of infection. A list of the most common starting points can be found in the AutoStart entry point manual and in the list of ShellOpen control keys. This task is best performed by experienced users. If you accidentally delete or change a legitimate setting, save the registry before you start.

Stop more infections

These programs may damage your system files or other Windows settings. A common feature of malware is to change your browser’s home page, which could reinfect your computer. They can also prevent you from surfing, posting ads or just being boring.

Before starting your browser, check your login settings and home page. To do this with Internet Explorer, in Windows 10, click on the Start button, select Control Panel, then Internet Options. In the General tab, search for the home page settings, then make sure it is not a strange website. For Firefox, Chrome or Edge, look for the homepage setting in the browser configuration window.

Reinstall Windows

Insert your Windows installation disc into the DVD drive. If you do not have a Windows 7 disk at retail, your computer has received a disk from the Windows 7 operating system.
