Hi swpierce, what happens when you run your antivirus programme?
Doing a quick Google, it looks like the .htaccess programme can be hacked so that when you undertake certain actions you get redirected to a site containing malware (in this case the redirection appears to be BV:redirect).
But the strange thing is, this process seems to be something that happens within a website. Are you running a website? Another question is from where and when did you download Rising Sun? It may be that the hosting site is compromised which is a bit of a worry.
