Hello, everyone.

As a newbie to this site (but not really to security systems), I've got a problem with IE:
When i type a mispelled URL the "cannot connect to server" page appears but just after that there's a redirection to a search website (www.lop.com). I went there and I can download a desinstaller but before I wanna know what setting they have modified into my IE.
Do you have any idea?

Thanks in advance for your reply.
