Try opening the task manager, maybe you'll find something suspicious, especially if it ends with ".dll".
Also try going to start and run, type "msconfig" then startup tab, and again try to find something suspicious in the list of programs that start with windows (if you have windows). Also while your there you can stop some programs from starting to make it faster when it boots.
You can also try the register editor. Type "regedit" and expand "hkey_local_machine - software - microsoft - windows - current_version - run". Now again do the same thing, find something suspicious.
Also if the folder "run" has more folders in it, delete them, since they surely are viruses.

Also you could always reformat.
Hope this helps.
EDIT: It seems the servers are back to normal.
