I have WinPatrol so it pops up whenever there is a homepage change...and it happens alot.
The installer thing pops up whenever i click on a link or start up windows explorer, its very annoying.
In answer to wingy's questions, theres no similarity in the sites that i know of - i dont go on porn sites if thats what you mean. Also, i tend not to download things so i doubt it will be that.
