Tips: What to Do the Moment After Expected PC Virus Exposure
No need to panic when you suspect your computer has a virus. Here are some simple steps.
Most malware is already familiar to the folks who write antivirus software. If you think you may have just let a virus onto your computer, unplug the network connection and run a scan.
When all else fails, go to Control Panel > System and Security, and select Restore your computer to an earlier time under the Action Center. This simple step removes any software you have installed in the last several days (but also restores your files to their previous state).
Restarting your computer in Safe Mode may pause the problem, as this mode disables many features that viruses like to use. Hold down the F8 key while the computer is restarting, then run a full system scan while in this state.
