I recently had an annoying encounter with a trojan on my Windows XP SP2 system. Every time I opened an Internet Explorer Browser window or tried to use Windows Explorer, a “Critical Error!” message popped up that said:
Attention, Michael Lind! Some dangerous viruses detected in your system. Microsoft Windows XP files corrupted. This may lead to the destruction of important files in C:WINDOWS. Download protection software now! Click OK to download the antispyware. (Recommended)
I was given the choice to click Yes or No. I didn’t dare click Yes, but clicking No just popped up a browser window with a realistic looking antivirus scan simulation.
I tried my usual tools to attempt to eradicate this malware:
- Norton Antivirus 2007 did not find anything
- Spybot Search and Destroy 1.52 did not find anything
- Ad-Aware 2007 found “IE Antivirus” and said that it removed the malware, but the behavior persisted
Fortunately I was able to find a nice description of IE Antivirus and how to eradicate it at Bleeping Computer. The anti-malware tool that did the job was Malwarebytes’ Anti-Malware. The free version managed to detect and eliminate IE Antivirus using just the quick scan mode.
Thanks Bleeping Computer and Malwarebytes! I now have yet another reason to recommend Firefox!
