Win32/Nuqel.E is commonly mentioned in bogus warnings and error messages generated by rogue anti-virus programs Antivirus System Pro, AntiSpyware Soft, AV Security Suite, and Spyware Protect 2009. In pop-ups generated by Spyware Protect 2009, it will often be mentioned along with Banker.Fox.A. Win32/Nuqel.E error messages are almost always associated with some kind of rogue antimalware scam.

Win32/Nuqel.E Causes Intentional Confusion

Rogue anti-malware programs take advantage of the history of Win32/Nuqel.E in order to give the bogus warning messages some extra believability. There actually is a virus called Win32/Nuqel.E, which is a worm, and can replicate itself and seriously damage a computer. On the other hand, it's been a while since the Win32/Nuqel.E worm was a serious threat, so it typically isn't going to be detected by any real anti-virus application, because it just doesn't really cause infections anymore. This means that if you get a warning message about Win32/Nuqel.E, it is almost certainly because of an infection with a rogue anti-virus program.

Common Behavior

Win32/Nuqel.E error messages will pop up extremely frequently when an associated rogue anti-virus program is present, in an effort to convince you to buy the bogus software to remove the bogus threat. Win32/Nuqel.E will also purposely make it look like your computer has all the symptoms of a virus, and will cause system slowdown and crashes in order to freak you out. Win32/Nuqel.E rogue anti-virus applications disable all anti-virus and anti-spyware applications and may interfere with the use of other programs, as well. Most disturbing of all, Win32/Nuqel.E rogues may capture keystrokes or otherwise steal personal information.

Error messages that warn of imminent threats posed by Win32/Nuqel.E cannot be trusted and should never be acted on without very careful consideration.
