I've suddenly got a firewall alert everytime I run IE asking to allow or not allow backgroundhost.exe. I've searched my files, programs and toolbar add ons for this filename and for SmartInLine and they are not there...I've run a full scan and it still didn't remove this annoying alert every time I use IE. PLEASE HELP!
