Do you do the same thing every day that you visit this site?
Do you visit this site the same time every day?
Have you tried another browser and visit this site?
Perhaps you could delete all your temp downloaded files, and perhaps cookies too, run Ad-Aware or something. Then (to be sure) reboot, visit RHP again, and see if it comes back.
Anyhoo, perhaps the AD is lying about spyware, but you sure do have adware! lol.
BTW, i never get ads (pop up or banners) with RHP, not even when i was a non-sub. I have an adblocker.
