### What is WinFixer 2005? It warns me about errors in my registry

Question:

I had a message box pop-up that supposedly (?)comes from Internet Explorer and warns me about errors in the registry database. It offers then to install a tool (?) WinFixer 2005 to check my computer for free (Recommended). The message box was a real message box (not a browser pop-up window) – here is a screenshot:

Anything that offers itself (as it is likely in this scenario) sounds suspicious. There is nothing wrong with free software. I am a big fan of open source software which can be both free like a free beer or free like a free human being (free from license limitations).
However, software that comes uninvited for free may not be so free after all. It probably wants to install further spyware or send data back to advertising servers. And yes, it is possible that they try to send back the user ids and passwords that browsers store for in local files for your convenience.

That WinFixer tries to also install an Active-X control from WinSoftware, certified from Thawte Code Signing CA. ‘Certified’ only means that this download indeed comes from WinSoftware.com. It is not any kind of endorsement of this software.

What is WinFixer? WinFixer falls in the category advertising software. It secretly installs itself or any other item without the user permission or knowledge. You probably got it from a web site by accidentally clicking on a confusing ad (you know, those seemingly uncloseable browser windows). When WinFixer is not running, popup and popunder ads are displayed while the main product is not running. That way it seems not to be related to the popups that it pretends to cure. Once you actually 'install' (activate) WinFixer, it keeps coming back, warning you about problems with your registry.

Below is a list of files and registry entries associated with WinFixer 2005.

| would like to get my hands on the A.H. behind Windfixer. I can't beleave that somthing so destructive and sly has been going for so long. My PC has been infected twice and the only way I've found of getting rid of it is to restore to a previous date.

is there another way to get of it besides restore to previous date? I tried that already and it didn't work. I can try it again though...

Winfixer is a bogus rogue antivirus, but for me, is very easy to remove. Just download Ad-Aware Free, and Spybot - Search & Destroy. Run a full scan with both of them, and then download AVG Anti-Virus free, and then download avast! home edition. If you need more help go to youtube.com/learnyourabcsright. My channel for security.

By the way, delete anything spybot and ad-aware finds. It should remove winfixer. If you encounter any other problems try a scan with avast and avg. And winsoftware only makes viruses so they can extort money from people.
