Complement your antivirus with Malwarebytes Antimalware (MBAM) http://download.cnet.com/Malwarebytes-Anti-Malware/3000-8022_4-10804572.html
Update the program before running a scan. See if MBAM finds the cause of the redirect. If not, try using:
SUPERAntispyware (SAS) http://download.cnet.com/SuperAntiSpyware-Free-Edition/3000-8022_4-10523889.html or it's Portable edition.

I have Windows XP - Norton 360 - not an expert... (lol)
Norton has protected me from a bunch of invasions lately and I seem to be on top of the fake scan pop-ups, etc. BUT I cannot search the net without getting sent to an unwanted website - not all are bad sites - just not where I want to go. I would like to download something that is compatible with my Norton 360 to stop it from happening - lots of sites involved!
