The same thing happens to me
avast home works fine
but the pro version stops all windows based java script from working
all javascript in IE stops working
all javascript in windows stops working, like searching for files or the help and support center
also I can't access the control pannel to see if the services are still running after an uninstall
I've had this before and reinstalling windows fixed it, but this time I can't even do that, so I'm having to use another computer
odd thing is javascript in opera works fine
I really like avast and I was going to buy the pro version for all my companies computers but I can't if it wont work
