First you need to get rid of them.. Try the freeware program called Spyware Terminator. It has an option for ClamAV you can use that too if you don't have AV program already. To stop the popups I use Ad Muncher it's not free but it been around for years. Still I use 3 layer popup stoppers to stop the popups.. IE SP2, Ad Muncher and Armor2net (firewall)
