thank you for your advice, and i will follow it. I run vista home premium---3 gb ram. I use western digital my book for back up. Haven't installed anything new. Yahoomail and web pages just sit there and blink and refuse to budge when i try to close out with the x or minimize. I go to taskbar and close or minimize by right clicking the page. I use avg internet security suite 9,0,801.
I am having the same problem! Also using avg 9.0.801& Firefox.
Internet just freezes & i have to go to task manager to close Firefox.
I immediately can open it back up & everything works great for awhile .... Then it happens again!
The only thing i have noticed is high cpu utilization since the first of April.
