Keep in mind that removing temporary files doesn’t always fix the malware problems, but it won’t hurt you to try it.

Solution 3 – Scan your PC with an antivirus tool

If your PC is infected, first thing that you need to do is to perform a detailed scan with your antivirus software. Depending on the size of your partition and your search options the scanning process can take a while, so you’ll need to be patient. After the system scan is completed, you’ll be asked to remove the infected files.

If that doesn’t help, you might have to use a different antivirus tool. Although antivirus tools are a necessity, no antivirus is perfect and a single antivirus can’t protect you from every threat. To do that, simply download a tool such as Malwarebytes, install it and download the necessary updates. After that, disconnect from the Internet and perform the scan. Wait while the antivirus scans your PC and then remove the infected files. Malwarebytes is one of the most popular tools for removing malware, but you can download and use any similar tool. In some cases you’ll have to download and use multiple tools to remove the malicious files.

Solution 4 – Check your web browser

Before you perform a Windows 10 reset we recommend to create a backup of all your important files.

Some of your files can be recovered by special software if you decide to use this option. Fully clean the drive option will delete all your files and applications, but you won’t be able to recover them by using this method. In most cases you can choose Just remove my files option to fix any problems with the malware.
  5. Now you just need to click the Reset button and the reset process will start.
