"My computer has a virus": what to do

Falls Technology Services · Idaho Falls · October 25, 2026

Many "virus" warnings are scam pop-ups, and many real infections show no warning at all. Here's how to tell, and what to do.

Signs of real malware

Probably a scam, not a virus

A web page shouting that your computer is infected and telling you to call a number. Close the browser; see our page on that pop-up.

What to do first

  1. Disconnect from the internet if you suspect something is actively wrong
  2. Don't type passwords on that computer until it's clean
  3. From a different device, change your e-mail and banking passwords and turn on two-step sign-in
  4. Run a full scan with Windows Security (or your antivirus)

Cleaning up properly

Removing what the scan finds isn't always enough: some malware hides or comes back. We remove it, check browser settings, extensions and startup items, update everything, and make sure your accounts are secured. If a computer is badly infected, a clean reinstall with your files copied across can be the safer choice.
