I have a similar problem to http://www.techspot.com/vb/topic175275.html and http://www.techspot.com/vb/topic172736.html Essentially my computer just shut off without warning, and when it restarted all my desktop files were "gone". They still existed, I can search for them and open them, but I am unable to see them. Going into either of my harddrives doesn't actually show me anything curiously enough. Folders everywhere are empty, but the files are obviously still there. The task manager sets off a blue screen and many files are unable to be overwritten or accessed. Then this "System Check" program starts opening and trying to "repair" my harddrive. Ironically, I had just finished my Kaspersky trial the other night and was planning to uninstall it today. Well, I can't, it's unable to uninstall due to the fact it can't write to a specific file in the "installer" folder. So I'm stuck with a virus program I can't use. I did have MalwareBytes, tried to run it, it was unable to update. I took the version from the five step guide, and installed it in the C: drive instead of Programs (x86) and it was able to write itself onto the drive. I've posted the log below: Malwarebytes Anti-Malware 18.104.22.1680 www.malwarebytes.org Database version: v2011.12.29.01 Windows 7 Service Pack 1 x64 NTFS Internet Explorer 9.0.8112.16421 Jackie :: JACKIE-PC [administrator] 12/28/2011 8:03:19 PM mbam-log-2011-12-28 (20-03-19).txt Scan type: Quick scan Scan options enabled: Memory | Startup | Registry | File System | Heuristics/Extra | Heuristics/Shuriken | PUP | PUM Scan options disabled: P2P Objects scanned: 180386 Time elapsed: 2 minute(s), 40 second(s) Memory Processes Detected: 0 (No malicious items detected) Memory Modules Detected: 0 (No malicious items detected) Registry Keys Detected: 0 (No malicious items detected) Registry Values Detected: 0 (No malicious items detected) Registry Data Items Detected: 1 HKLM\SOFTWARE\Clients\StartMenuInternet\FIREFOX.EXE\shell\safemode\command| (Hijack.StartMenuInternet) -> Bad: ("C:\Users\Jackie\AppData\Local\jmq.exe" -a "C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -safe-mode) Good: (firefox.exe -safe-mode) -> Quarantined and repaired successfully.

(end) It detected two things, I removed them both, restarting now (will post the GMER log once that's dealt with). Thank you for any help in advanced.
