Hi all, recently my back button on IE6 does not seem to work properly, I have to hit it 3 or 4 times before it will go back to previous page, and allot of times it wont go back at all?

I have spybot search and destroy , ms antispyware,pestpatrol ,webroot spysweeper,spywarebaster= blocking host files,system mechanics spython, and adawre se . all show no spyware, and my avast AV shows no viruses?

Any Idea why my back button is having problems going back? Thanx newme
