You may get a pop-up with a scan that detects tons of infections. The scan will probably not look familiar to you. That’s because it’s fake.

Do not click on buttons or links. If you cannot close the pop-up, restart your computer and run your own legitimate virus scan as soon as possible.

If you notice an increase in data usage, your computer may be infected. Adware can run in the background and perform endless clicks to generate money for cyber criminals.

If your friends receive invitations from you on social media that you didn’t send, your account has probably been hacked. You can also see that friend requests and messages are sent without your input.

6. Slow internet and video buffering

If you notice that webpages load slowly and videos take too long to play, it could indicate DNS hijacking. This allows hackers to redirect your internet traffic to their own insecure servers. Aside from slowing things down, this can expose your privacy and information.

If you enter an address and end up on another page, something is messing with your DNS settings. To check your router’s DNS settings, you can use online tools that also offer advanced hijack protection, such as Cloudflare or Quad9.

A program can crash due to a bug or a wrong start, but if you find that this happens often, your computer may have been hacked with a virus or malware. The news gets worse if you find your antivirus software and task manager freezing or inaccessible.
