Hi there
This is likely a rootkit infection. Please follow these instructions carefully.
Please download
combofix.exe to your
desktop.
Alternate link.
IMPORTANT - You must place combofix on your desktop!!
Double click
combofix.exe & follow the prompts.
When finished, the tool will produce a log for you at
c:\combofix.txt.
Post that log in your next reply.
Note: Do not mouseclick combofix's window while it's running. That may cause it to stall.
Assuming you can post a log, I'll move this thread to our H-J-T Forum.
