Hey all so I just picked up a machine. When I initially turned it on I got "Missing Operating System" I was able to run the Win 7 Recovery CD and fix the MBR allowing me to log in to windows. However, when I log in there are no desktop icons and the start menu is empty. I cannot access task manager either by right clicking task bar (greyed out) or hitting ctrl-alt-del (doesnt even show up)I dealt with this a while ago and it was easier to just backup the data using Sata to USB adapter and reimaging the machine. I was able to update and run Malware bytes and the scan came back clean. I also installed and ran AVG (free) with latest definitions again clean. I ran Kaspersky on the drive while it was slaved from my pc and it said there was one infected file but of course my license expired last week so no resolution haha.

Anyways, Im under the impression this is a rootkit and can be cleaned. When the drive is slaved I can see the data. I dont want to back everything up and do a restore and run the risk of restoring the virus. I am gonna try RKill and security essentials to see if I can make any headway.

Its an HP Tower running 32 bit Win 7. Nothing fancy. Dual core processor couple gigs of ram. Any suggestions would be much appreciated.

Hello, run these 2 if needed to get them back.

Pease download the following program to your desktop:

Unhide.exe

Once the program has been downloaded, double-click on the Unhide.exe icon on your desktop and allow the program to run. This program will remove the +H, or hidden, attribute from all the files on your hard drives. If there are any files that were purposely hidden by you, you will need to hide them again after this tool is run.


OR
Run SFC,System File Checker
