 Signs of viruses: Are you infected? 

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
