Hello there. I work at a small cafe and we have one computer used for financial records, time wasting, etc. Within the past week it's been infected with something I can't identify. The only thing I can recall doing the last day it was acting normally was playing a game called QWOP in Firefox. The next day I came in, the desktop and all of the icons on it had been replaced with just a blank blue screen. The Start menu was still visible, but none of the installed programs were showing up, and no files of any kind were accessible.
We have two user accounts on the computer, User A which we have always used, and User B which has been on the computer since we got it (it's refurbished) but never used. User A is the one with the missing desktop. Upon logging in to User B, the desktop was visible and there were a few icons (Recycle Bin, IE, Windows Media Player), and our installed programs were visible. Our files however are still missing. The folders they were in are there, just empty.
I was able to install Malwarebytes and it found something like 10-12 infected files, mostly HKey stuff, and a few Trojans as well. I cleaned it all up and restarted, but the desktop of User A was still missing, as were all of our files in both User accounts. I've gone through the same motions a few times, scanning with MWB and finding infections, then restarting, and no change. And in both user accounts I'm getting random IE windows about unresponsive scripts, even when I haven't opened IE myself.
And that's about all of the relevant info I can think of. Thanks for looking and I'll try to respond quickly to any assistance given.
