How to Fix a Hacked Computer

Hacking is a term used to describe a situation in which someone accesses files on your computer without your permission. If you suspect your computer has been hacked, it's likely that it was not fully protected. Unprotected computers allow hackers to gain control and ultimately take over the system. Hackers don't care who you are or where you're from. They just want access to your computer and files.
