TrojanDownloader: Win32/Renos.gen!Z

TrojanDownloader: Win32/Renos.gen!Z is a generic detection for variants in the Win32/Renos family. The Win32/Renos acts as a message displaying that the current antivirus security software the user owns is malfunctioning or failing and says that a new antivirus program should be installed.

The message is extremely misleading and completely false because it displays the message so it can trick into downloading rogue security software programs and fake detection programs. The Renos.gen!Z variant was first seen by Microsoft Windows and security users on the 8th of May, 2008 and the latest report published was May 25th, 2010. The original Renos.gen!Z variant has been decommisioned. However, there are still other Renos variants hiding on the web as well as other versions of the Renos.gen!Z trojan installer on some parts of the internet.

The trojan level is severe, due to the fact that the software it installed damaged some peoples systems and made others vulnerable to other trojan and rogue computer virus attacks.
