Trojan + Backdoor.Tidserv!inf Removal

Thank you very much for your help. The computer functions quite excellently now, no problems.

Symantic's Antivirus AutoProtect indicates that Backdoor.Tidserv!inf is still present on my machine, it don't see how it affects performance but I don't know how to remove it.

Please try and run MBAM now the rootkit is gone, instructions here:
