Hi,
Well, I have about the same problem here. I have Avast Home installed on 3 computers, but the only one running Win XP gets incredibly slow when Avast is doing his thing. Don't exactly know what it's doing, but the A-icon in the systemtray is spinning. Well, 'spinning' is a big word....it very slowly turns the A around in fractions of millimeters at a time. This takes about 3 to 6 minuts I guess, before it is finally done.
During those 3 to 6 minuts, I can't do anything with my computer. It is SO incredibly slow. Keyboard and mouse do respond, but very slowly too. I can type a couple of lines before I can see the characters appear on the screen. Some programs even generate "not responding" errors, which I ignore, because I know when Avast is done doing what he does, everything will turn back to normal.
Well, to make a long story short....it's beginning to annoy me.
Is there some way to fix this problem? Does it have something to do with Windows XP perhaps?
My computer is a P4 2Ghz with 1GB of memory.
Apart from this little problem, I just love avast and recomment it to anyone I know.
Thanks in advance for the advice.
Henny
