After you open and run an infected program or attachment on your computer, you might not realize that you've introduced a virus until you notice something isn't quite right.
Here are a few primary indicators that your computer might be infected:
* Your computer runs more slowly than normal
* Your computer stops responding or locks up often
* Your computer crashes and restarts every few minutes
* Your computer restarts on its own and then fails to run normally
* Applications on your computer don't work correctly
* Disks or disk drives are inaccessible
* You can't print correctly
* You see unusual error messages
* You see distorted menus and dialog boxes
These are common signs of infectionR*2;but they might also indicate hardware or software problems that have nothing to do with a virus. Unless you run the Microsoft Malicious Software Removal Tool and install industry-standard, up-to-date antivirus software on your computer, there is no way to be certain if your computer is infected with a virus or not. If you don't have current antivirus software installed or if you're interested in installing a different brand, visit our Windows Marketplace for software from other companies.
