UnVirex Description

Type: Rogue AntiSpyware Programs

ScreenshotUnVirex is a fake malware cleaner program. In many cases UnVirex is disguised as a video codec download. Once your system has UnVirex installed, it starts to scan your computer detecting a video codec parasite that is claimed to only be removed with a full version of a malware remover application. UnVirex is not able to effectively detect or remove malware. UnVirex may come from the UnVirex.com website where it is falsely advertised and sold as an application that is able to provide protection against spyware, viruses, adware and malware.ScreenshotScreenshotScreenshot
