We broadly use the word “hacked” as an adjective for a compromised system or account. Hacking generally implies a hacker is in control orchestrating every move, but many hacks like viruses and malware don’t require active control. As such, for the purposes of this guide, we’ll discuss scenarios in which computers have been compromised, ranging from an actual hack to a garden variety of malware.
A hacked computer will usually behave erratically. You can watch out for a few markers that could be pointing toward your computer being hacked. Here are the most common ones.
- Frequent pop-ups — Constantly opening unrecognized windows on your computer.
- Changes to your home screen — Changes to the wallpaper, theme, or any other aspect of your home screen.
- Apps you don’t recognize — Icons or windows of apps you don’t recognize or remember installing.
- Frequent redirects in the browser — Constant pop-ups, redirects, or advertisements in your web browsing.
- Emails you didn’t send — Contents in your email inbox or sent email folders you don’t recognize.
- Performance issues — PC not performing as expected, programs crashing, overheating, or fans always running at high speed with noise.
- Suspicious social media behavior — Logins, posts, or messages on social media accounts that you didn’t initiate.
- Suspicious transactions — Worst case scenario, transactions in your bank or card accounts that you didn’t initiate.
