Repair Registry 2008 is a malicious system application made to take advantage of the unsuspecting internet users. The scam begins with user being redirected to some compromised website while surfing the web. The site pretends to make a system security scan and to find various threats and parasites. It then suggests purchasing the 'Windows software patch' which is actually Repair Registry 2008.
