searchgol.com appears to be a very sneaky malware that hops in other downloads (I didn't even do the usual just keep clicking accept on freeware things, not sure how I got this infection). It sets your home pages, search options & everything to searchgol.com/whatever. It has no Remove Programs entry and is pretty much invisible, impossible to uninstall. Definitely Malware, possibly virus (though my scans show nothing).
