Hey! So last night I started scanning through my computers, scanned the whole computer with MSE, MBAM, PANDA ONLINE and superantispyware and it was clean. Then I plugged in my external harddrive to scan, I scanned that one with MSE and then with superantispuyware and then MBAM. It didn't find anything. Then I scanned the whole computer AND the external harddrive. First with MSE, it came up clean. Then with superantispyware, it was also clean, but it found som tracking cookies on the pc, and I had to restart the pc. But heres the problem, I forgot to take the external harddrive out of the pc while restarting... Can this (if there is a virus) have made it boot into the computer, so AV's can't find it anymore? (I had autoplay turned off through "control panel" - "hardware and sound" and "autoplay") Lets say that there is a virus and it did do this, will reinstalling and formatting get rid of it anyways? Is this tool to be trusted? Does it work? : http://www.addictivetips.com/windows-tips/remove-autorun-inf-virus-with-autorun-eater/ please say if you know of any better ways to detect this. *More backround info in my last topic here (including list of viruses that could have something to do with it. https://www.instructables.com/community/USB-drive-virus-Do-I-have-it-What-should-I-do/
