This is some form of Browser helper.
Have you ran Spybot S & D or any spyware program?
If Spybot doesn't remove this, try BHO Demon.
You can find these with a Google.
I was uninstalling quicktime using add/remove and saw "Windows SR 2.0"... I seached my hardrive and there is an icon: a yellow #7 with a black ball and lightning bolt. I googled it and couldn't find anything.I It didn't show it's properties or it's location... I'm concerned it may be a bug of some sort. Any ideas?
