AVKiller Trojan is a backdoor Trojan application, which may cause severe damage to a computer system it has infected. The main aim of AVKiller Trojan is to lower internet security settings; however the popular function of AVKiller Trojan has recently changed. AVKiller Trojan is now most commonly used by renegade anti-spyware Trojan applications, as content for fictitious threat reports, which may resemble the following: “Warning!!! File: C:\WINDOWS\wml.exe Threat: AVKiller Trojan. Click here to visit PC-Antispyware web site.” Should a user stumble upon such a threat notification, it should NOT be trusted. It is simply a phony threat. Important to note: Do not download or purchase any software associated with the AVKiller Trojan threat application.
