VIDEO: How to Tell If Your PC Has Been Hacked

Think your Windows PC might have been hacked? Strange pop-ups, browser redirects, unfamiliar user accounts, or other unexpected changes could be signs that someone has accessed your computer.

Before you assume it’s just a glitch, there are a few quick checks you can run to spot suspicious activity. Here’s how to check whether someone else has been using your Windows PC.

• Step 1: Press Windows + R to open the Run dialog box.
• Step 2: Type in "NETPLWIZ" and tap "OK."
• Step 3: A window will pop up showing all user accounts on the system.

If you see any account listed that you didn’t create, that’s a problem. It usually means someone gained access and set up their own account to stay in without raising alarms.
