Okay, a few days ago i was doing research for school about Giant Clams (random invertebrate), and followed a link to a website. I realized right off that this was a bad site because before it loaded the page what looked like a legitimate windows box came up telling me my computer had viruses. I'm not dumb and knew this was a hoax, so I quickly exited the box but just before I exited the browser (Google Chrome) the website started to scan my computer. It scanned about one file before I could exit, but I saw for a split second in the bottom left hand corner that something with anti virus in the name got downloaded. I looked in the downloads folder but saw nothing there. Can anyone help me?
Browser: Google Chrome
OS: Vista Ultimate 64 bit
Security: McAffee (free with Comcast)
One extra note, virus scans find nothing but I know something was downloaded. Maybe because I didn't access the download before exiting the browser it deleted it?
These fly-by download and install rogue anti-virus programs do various things to prevent their removal.
This can include things like avoid detection, disable certain functions (apply restrictions) i.e. Task Manager, Control Panel, hijack hosts file. Disable antivirus & malware scanners. Lie dormant for a period then become active....
For peace of mind it is best to run a scanner that can weed out these kind of threats and eliminate them.
The best scanner around at the moment is Malwarebytes' Anti-Malware:
btk1w1 is a good voice in the world of malware.
I have read his posts both here and in other places and he knows what works.
I also run malwarbytes on my system and fortuntly have found nothing with it.
It runs a very detailed scan that on my system takes close to 1 hour to complete.
I can say after watching it that it seems to check some areas that I know other scanners dont.
Have you tried to get it to work in safe mode?
Often times different bugs dont want to be killed so they try to prevent programs that can kill them from starting.
Many times safe mode will help to get it run.
