Fake Messages Appearing on the Screen: One sure sign that your system is hacked is once you see some fake virus messages popping on your system screen.

Such warning signs can assure you that you need to scan your system.

Passwords Changing: One serious sign that hackers have hacked into your system is when you see that your online passwords get changed unexpectedly.

Cursors Moving Around and Software Starting: Once hackers take control of your system, they try to access it. During such times, you may find unexpected movements in the cursor or any file or program starting unexpectedly.

    Another subtle method of finding if your computer is hacked is by checking your data consumption. A lot of bandwidth is consumed by the malware as it receives commands from the remote server, scans your machine and keeps uploading the files to the hacker.

      Right Chandana. Most of the time event bandwidth usage tells us that something is happening weird and need to inspect everything. Thanks for your suggestion.
