How to Remove PC Repair (Uninstall Guide)

Tell your friends:
PC Repair is a rogue computer optimization program that offers fake system scans and states that a large number of problems — hard drive failures, registry errors — have been found on your computer. In reality, no problems were detected. PC Repair entices you to provide your credit card information and purchase software that you don't actually need. This type of malware is a straight gateway to identity theft, that's why you should never purchase software that looks odd or you don't know where it came from no matter how generic it may look. Only download, purchase, and use software provided by established and well-known vendors. And what do you know about PC Repair? Probably nothing, except this article. Cyber crooks usually use a few common scareware scams: fake online virus scanners, free downloads/warez that actually laden with malicious software, misleading pop-ups and backdoor Trojans that give malware authors "back door" access to your computer. PC Repair is not an exception — it's being distributed using exactly the same methods. It's not a virus, but more like intrusive and annoying software. However, it's still a threat and has to be removed from your computer. If your computer is infected, please follow the steps in the removal guide below to remove PC Repair and associated malware.
