riskware ‘Invader’ messages on Kaspersky Internet 6.0

I just purchased and downloaded Kaspersky Internet 6.0. Since that time I am being plagued with a ton of error messages about something called riskware ‘Invader’ modifying files. At the same time I am getting reports from KI 6 that Iadhide4.dll is needing to be Accepted or Denied before a program I want to launch can run.
Does anyone know what might be happening? I ran the Trend Micro HouseCall program from the web with no issues reported. Same with X-Cleaner Deluxe. Is this IadHide4 dll a virus, worm or trojan? None of the main antivirus companies mention it in their encyclopedias.
