Hi, I keep gettting popups for a program called "Winfixer" that promises to fix errors on computers, but--in reality--can cause one’s computer to crash. I have Windows firewall installed, as well as popup blockers and virus protection, but can’t seem to keep Winfixer from attaching itself to my files. Does anyone know where this file is coming from and what website(s) might be transmitting it? Thanks for any help.
