I was having huge slowdowns with Thunderbird 3.0.4 - taking up to 15 seconds to show a message and as much or more to delete the same message! Firefox 3.6.3 was much slower as well.
After some playing around with Avast!, I found that if I stop the "Behavior Shield", everything speeds up back to normal.
I am curious - is there something else that could be at the root of this slowdown as well? And am I at terrible risk by doing what I did?
Thanks for any input.
I have a Toshiba A200 laptop running Vista Home Premium, Thunderbird 3.0.4, Firefox 3.6.3, Avast! 5.0.545
