:: Browsing web causes distortion to my audio ::

Hey GeekPolice!

I recently cleaned out some viruses on my computer and installed new security programs.
I always have my iTunes playing. So when I go to a website that takes a while to load,
the iTunes audio gets distorted and makes a crackling and static sound as the website is loading.
When the site is done loading then the music goes back to normal.

Do I need to reinstall some audio codecs or drivers?
Please keep me posted.
Thanks!

Sorry ... what section should this be in?
