Virus win32/Agent.AC trojan

I cannot seem to clean, rename or delete this virus in file C:\windows\systems32\sqldfcp.dll.  When I try to clean, rename or delete it I get the error "Error while deleteing - file is locked up".  I have tried using Pest Patrol 5, NOD32, spybot, and hijackthis.  This may also be related to the problem I am having with my IE bringing up "about blank" all the time which I am also having trouble fixing.  I am not sure which to work on first so I am kinda working on both.

Below is my hijack info:
