SVCHOST.exe slowing down CPU


SVCHOST.exe Everytime I start Firefox, this system file is hugging the cpu for about 5 to 10 mins at start up. I have changed the browesr vers from 3.6 to 3.5 but the problem is still there! I have disabled NoScript and Java quick starter but no success! The only addon is the Camera Pearl page saver.

Any help to stop this exe program?
