Script Shield and Grooveshark madness

Can you guys check out why is Script Shield scanning scripts every second even when music is simply playing on Grooveshark? Every second of music playback, script is scanned on http://grooveshark.com . I find that a bit strange…

Using Firefox 6.0.2 and avast! 6.0.1289

Yes it’s so strange… I don’t know why!

It’s Grooving to the music

LOL ;D

I can’t help, but I can confirm that I uninstalled the script shield do to non-stop scanning, and slowing down my web page loading too. I’m just running the file, web, network and behavior shields along with the auto sandbox.
