When a virus infects your computer, it makes the machine’s performance slow down greatly. Running a virus scan means any infected files may be cleaned by deleting the file completely, meaning you may experience data loss.

Microsoft Safety Scanner is a tool designed to locate and remove malware from Windows PCs. It only scans when manually triggered, then you get to use it 10 days after you download it.

This means you need to download the latest version of the tool before you perform each scan on your computer.

However, the Microsoft Safety Scanner tool doesn’t replace your antimalware program. It helps remove malicious software from your Windows 10 computer.
