Pop up/redirect problem

Lately I've been having trouble with a page redirect when I first access the main HPotD forum page. It happens about three out of five attempts and only on this site. My virus protection completely shuts down the attempted redirect and lists the page as such:

http://www.activeplayer.us/download/...ualoffer=false

Not sure if that helps much, just thought I'd point it out....

Can I ask if anything happens again (here on the forum) can you please report it again, and also where it's redirected you to!

That would help alot!

Thanks!
