I don't find anything with Google that is really incriminating, but a couple of threads at malware removal sites show HiJackThis logs that have the asafetyguide.com site listed in the browser "Trusted Sites" list.

The logs were posted for removal of specific malware programs, and the experts didn't make reference to the browser list; but presence there means that the person running the computer had deliberately added the site, or that they were "surreptitiously added" by malware.

IE Tools|Internet Options, Privacy tab, Sites button should show you whether something has added the website to your "approved" list. If it's there, I'd delete it, or block it specifically - and while there make sure mudcat.org¹ is on your list.

¹ If mudcat.org isn't on the list, and your computer keeps its cookie, you're probably running at a lower security level than you should really be using, or you're using an obsolete version of IE that should be updated.

The site for rogue software shows a last update May 2007, which is much too old to be really useful(?). The info appears pretty good, and would help if a bad thing is on the list; but things change too fast to use a list that old to indicate that something it doesn't list isn't bad.
