Niether of us will touch Sp3. For both of us we have found that it only degrades the performance of Windows Home XP2. Sometimes one even has to wonder if it was an item designed silmilar to the sword that a bullfighter sticks into the bull to finish the bullfight. Sort of a pre-Win-7 phenomenom. In any case, Sp3 never has made any computer I know operate better, almost consistently… Worse.
Comodo completely updated their firewall on (I think) the same day that Avast updated it’s anti-virus software. There are bound to be surprises.

;D(off-the-side: I almost forgot that Vista preceded Win-7, but than again, most people don’t remember Windows Me either!)
