foxymama, winfixer (the 'old' variety) was only a bit difficult to remove, however the newer variety often contains a rootkit. This is why a HJT log is necessary and posting it in the HiJackThis (Analyze) section for MicroBell to give you the exact items to download and run, the files to delete, and the process for cleaning is so very important.
I know it is a royal pain in the tush, and our computers are very important! This is why you need expert help in getting cleaned up. The first step is to get the HJT tool, run it (fix NOTHING) and post it for MicroBell to help you.
