a short while back I was myself having internet explorer popping up by itself with an ad at any given time. Ran AVG and found a trojan lurking in there, quarantiened (sp) it and now IE does not appear. I do not even use IE, but windows has to have it nearby. But when I read your post I thought 'This was what was happening to me'?!
Also this forum features an automatic re-sizer that will put whatever size you have into the right perportions .....

Man my spelling sucks tonight!
