i had a tdssserv.sys infection. I thought combo fix removed it but the system is still not working i have a file NTUSER.dat which has put itself in MY DOCUMENTS with lots of other files...i cannot delete this...it says it is part of the system process. I downloaded Combo Fix.rar and opened it and when it didn't open properly i scanned it and it was a AGENT-QZQ (TRJ) so i deleted it but i think it was too late!
HELP
