Windows Startup Repair is a clone of the rogue defragmentation tool System Repair. Windows Startup Repair was first detected in the Summer of 2011, so anti-malware programs need to be updated up to that date, in order to detect a Windows Startup Repair infection. ESG team of PC security researchers strongly recommends removing Windows Startup Repair from your computer as soon as Windows Startup Repair is detected. An anti-malware tool that is fully up to date should be able to detect and remove any trace of a Windows Startup Repair infection.

What You Can Expect From Windows Startup Repair?

Windows Startup Repair pretends to be a system optimization tool; specifically, Windows Startup Repair pretends to be a defragmentation tool. Defragmenters are useful system utilities that Windows users need to use regularly to maintain their operating system as efficient as possible. However, the Windows Startup Repair defragmenter is completely fake. Windows Startup Repair will perform a fake scan of your computer system and then return a long list of nonexistent errors. Even worse, Windows Startup Repair will also pester you with constant error messages indicating that all kinds of things are catastrophically wrong with your computer, from a faulty CPU temperature to missing files. ESG team of PC security researchers advises ignoring all notifications and error messages that are displayed while Windows Startup Repair is installed on your computer. These are all designed to scam computer users into buying Windows Startup Repair to fix the problems that Windows Startup Repair supposedly finds.

How Windows Startup Repair Infects a Computer?

The bogus defragmentation tool Windows Startup Repair is typically delivered by a Trojan designed to download and install rogue security programs. Two Trojans that are strongly associated with Windows Startup Repair are Zlob and Fake Microsoft Security Essentials Alert Malware Trojan. Almost all Windows Startup Repair infections are associated with one of these two Trojans. According to ESG security researchers, these two Trojans are commonly disguised as fake video codecs for viewing adult videos online. Usually a pop-up window will appear, indicating that the user must download a given codec, in order to view a video. This codec will really be a cleverly-disguised Trojan. As soon as the Trojan is downloaded, it will use different tactics to convince the computer user to allow it to install Windows Startup Repair or similar rogue security programs.
