Signs of computer infection

If you see that your computer acts strangely, namely: 

  • abnormal messages and images are displayed; 
  • CD-ROM tray opens and closes unexpectedly; 
  • some programs are run arbitrarily on your PC;
  • a message is displayed informing that some program is trying to connect to the Internet, though you have not initiated any actions.

then it is likely that your computer is virus-infected. See KB790 for other signs of computer infection.

  Still suspect your computer is infected?
