*Remember, needs to be boot-time scan if at all possible. Many malicious programs and such do not start working until the pc starts up. By scanning before this happens OR via a safe mode scan you're able to see it "dormant". Do the safe mode scan if boot-time is not offered via your anti-virus program because only a few very complex viruses and such can even run in safe mode - not many can so by running a boot-time or safe-mode scan your anti-virus can properly identify the virus and stop/remove it properly since it never "started up" per say i.e. the virus didn't have time to start and mask itself as something else.

Edit:

1. Click Start
2. In Search Box type "msconfig"
3. Now a new window comes up "System Configuration" w/ some tabs
4. Click on "Boot" tab
5. Under "Boot Options" in the Boot Tab click on "Safe Boot" then select "Minimal"
6. Click Apply
7. Restart if prompted else close the dialog box and now restart.

^ When the pc restarts its now in safe mode, bring up your anti-virus and run a scan - some anti-virus programs will not work in safe mode where as many have the DOS style black box only in safe mode.
