Companies such as Kaspersky, Bitdefender, and Avira offer antivirus rescue disks, so you can download and use any of these or use any other rescue disk that you want.

    • 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.
  6. Follow the instructions on the screen in order to complete the reset.

If the issue still persists, you might have to reset Windows 10. By resetting Windows 10 all your files and applications will be removed and hopefully, the malware will be removed as well.

Before you perform a Windows 10 reset we recommend to create a backup of all your important files. If you can’t access Windows 10 at all, you’ll have to use Linux Live CD to back up your important files.

Once your PC is running, be sure to download and install antivirus software and perform a system scan just in case. Before you transfer your backed-up files be sure to scan them with your antivirus.

In order to prevent these types of problems in the future, be sure to frequently update your antivirus and download the latest Windows 10 updates.
