    If I restore my hard drive to factory settings, does that get rid of the virus or will i have to manually find and remove it?

    After hours of trying to remove this virus, I found multiple websites(using an uninfected Netbook)that discussed how to get rid of the virus, but most of them wanted you to download and buy software removal programs. Finally, I found a website with a comment from an IT expert who said to go in to System Restore and restore to an earlier version. You can try going in from the start up, but I got an error message that the system restore tool could not be found. I was able to go in from my control panel and access System Restore. Pick a day earlier than when you first starting having problems. It worked like a charm. Malware is gone and no more annoying, irritating pop-ups that won’t allow you to browse. Good luck.
