winlogon.exe

Each time I launch IE, winlogon.exe process runs under my username in task manager.  I have read that this is probably the email worm W32.Netsky.  I have done everything that mcafee and symantecs websites have said to delete the worm but it has had no effect.  I have run adaware, Defender Pro antivirus software, and FXNetsky (downloaded from Symantec) all to no avail.

 

Can anyone help???  I'm thinking about reformatting and just starting over...
