Also if you can , slave the drive into another machine and run an antivirus such as avg or antivir. I highly disreccomend norton, however that is my opinion.
Also, if you know the virus name or files, you can do a few things. One search the registry for the names of the files, delete the keys and use killbox or unlocker to delete the stubborn files
Also id reccomend using ccleaner to empty out all temp locations.
Also, a good registry cleaner helps remove leftover keys.
If by any chance you use antivir, here is how I reccomend configuring it. (By the way, antivir does not get along with norton and they will conflict if both are on the same machine)
This is to setup antivir after it has been installed.
Right click on the logo in the taskbar(a red square with a white umbrella), then left click configure. Towards the top left, you will see a box beside expert mode. Check this box. Now click the + beside scanner, and now the + beside scan. This will expand them.
Now click on scan itself to where it is highlighted. Now to the right under files, select the circle beside all files. Now click on action for concerning files. To the right, click the circle beside automatic. Now to the right of that, set primary action to repair and secondary action to delete. DO NOT check the box that says "copy file to quarantine before action".
Now click on archives to where it is highlighted. Make sure all boxes on this page are checked, if not check them. Now click on heuristic. To the right under win32 file heuristic, check the box beside "win32 file heurisitic", then click the circle beside medium detection level.
Now click the + beside guard and the + beside scan to expand them. Now click on scan to where it is highlighted. To the right under scan mode, check "scan when reading and writing". To the right of that under files, click the circle beside "all files".
Now click on heuristic to where it is highlighted. Check the box beside win32 file heuristic, and then click the circle beside medium detecion level. Now click ok and antivir is now setup for scanning. I highly reccomend doing a scan now.
