I'm running XP with service pack 3 and IE8. IE would open multiple time with ads from various sources. For 2 days I ran all the good stuff and was convinced I had a rootkit. I ran all the programs from safe mode with no results. At one point Abode Reader opened by itself, it was the second time that happened, and I immediately removed Reader8 as I was aware of problems with vulnerabilities. One of my fixes was to uninstall IE8 and now run IE7 and have not had a problem since. IT'S ONLY BEEN ABOUT 5 HRS. SO I'M HOLDING MY BREATH! But I'm thinking Adobe Reader was the problem and hope nothing has been left behind. Comments?
