I'm new to e-exchange and could use some help. I seem to have something infecting my pc. I am running XP Pro and a program called "conduit search" has made itself my default browser and homepage. I can no longer change my homepage with internet options or change my default browser. It's infected IE and Firefox. My Bit Defender and all other scans have found nothing. The "conduit search" claims that it's searches are done on behalf of Bing (doubt that). It has also deleted and altered some of my files. Has anyone heard of this, and does anyone know how to get rid of it?
