Yesterday night, my PC was infected with Antivirus Live trojan, that would not let most of the applications run. It keeps on giving fake scan results and pop ups asking you to buy their antivirus product. It even changed the proxy settings of IE to always go to their product's home-page and nothing else. I am really surprised why NOD32 didn't catch this, full protection turned on. I usually run NOD32 and MBAM(malwarebytes anti-malware, full version with real time protection) simultaneously. I turn off MBAM while I am playing Modern Warfare 2 as it seems to cause some problems with IW.net servers (probably IP protection feature of MBAM). I forgot to turn it back on after exiting the game. A few hours after that my wife was browsing and got my PC infected with this Antivirus Live trojan. When it was in the infected state, NOD32 was still running. I started a scan and it found nothing. I couldn't launch MBAM as the trojan was preventing launching any new applications that were not already running. I had to reboot in safe mode and clean it with MBAM. I don't have any files to send to you guys, but it generally looks like this. <random letters>sysguard.exe. Plenty of info on the internet about this new trojan. Hope, you guys keep NOD32 up to date, to tackle these kind of things. Whats up with the advanced heuristics and all? This kind of aggressive fake antivirus behavior is not flagged by NOD32, looks bad to me. PS: I am in no way bashing NOD32, but expecting you guys to be more effective in dealing new threats like this. I am a 2-year subscribed customer to ESET.
