Try running the following from safe mode (Getting to safe-mode) Sysclean
you'll also need the virus template file from here lpt***.zip
remember to extract the contents of the zip file into the same folder as Sysclean.com
If your good with the command line also try Sophos Command Line scanner
this command will scan all of your hdd's SAV32CLI.EXE -F -di -remove -dn -mbr -all -zip -p=avscanlog.txt and give you a log file to review afterwards.
If you can't get into safe mode download the following - Ultimate Boot CD
however you will need to update the definitions on the disk see here
how to do that. Alternatively download a archive version of Public AntiVirus
again this will need updating but full instructions are here.
If you want a smaller download look here for instructions on how to create your own boot CD
.Also try installing and running A2 Free and Ewido
I'd also run Spybot(Spybot Tutorial)
