Strangely enough. Few days after Fester got the winfixer bug. I had a customer bring in a computer with the same bug.
However, I don't think it was as bad as some of the examples that Curval posted. All this one had was the program, and when you tried to close it it would pop up a bunch of windows.
Easy enough to get rid of though, just boot into safe mode. Uninstall the winfixer program, and then delete the entries through hijack this.
