Based on several emails I've seen from readers, Winfixer (also known as WinFixer 2005) is a nasty bit of adware. It tries to install itself through confusing and alarming popups, and is resistant to many removal tools. Here's what I recommend to remove Winfixer.

First, make sure your Windows system is up to date. If you don't have Windows Update running on auto-pilot, I highly recommend that. From Internet Explorer, click on Tools, then Windows Update. This will ensure that you have the latest Windows security fixes and patches. Without that in place, you are wide open to many different exploits that can wreak havoc on your PC.

If you search for Winfixer at Google, you will find quite a few links to websites, forums and software vendors that claim to have the solution for Winfixer removal. However, as you mentioned, many of them are very geeky and require you to mess around in the Windows system registry. If you are an advanced user and follow these instructions very carefully, you may succeed in getting rid of Winfixer.

But if getting into the guts of the operating system sounds a little scary, you might want to consider using a malware removal tool written specifically for the task. Unfortunately, none of the free adware/spyware tools seem to be effective in removing Winfixer. Several people have told me they have tried Ad-Aware, Spyware Blaster, Spyware Doctor, Spybot Search & Destroy, Microsoft AntiSpyware and others to no avail. In some cases, the program claims to have removed Winfixer, but it reappears after a reboot.

Two software packages from reputable companies claim to remove Winfixer and other malware, namely Spy Sweeper and
Computer Associates PestPatrol. They're not free, but they should get the job done with a friendly point and click user interface.
