cmid32.dll infected with Trojan.Tofger and cant delete this file!

[xDylanx]

I have recently been infected by Trojan.Tofger with the file "cmid32.dll" I beleive this is causing me to be infected with Dialer.Silent over and over.
I can delete Dialer.Silent everytime I am infected with it but cannot delete cmid32.dll because it says "Cannot delete cmid32.dll: The specified file is being used by windows". Can someone please help me delete it?
and if possible explain where it came from and what is does?

Your help would be much apreciated Thank You - xDylanx
