How do I know when my computer is at risk?
Action Center
If the reports an alert, or if your computer behaves erratically, crashes
unexpectedly or if some of your programs do not work correctly, your computer may be
infected by malicious software. However, do not blame every computer problem on a
virus! If you suspect your computer is infected, the first thing to do is update, if you have
not already done so, and run your antivirus and anti-spyware software.
