Recently pop ups and banners started to appear while we surf the net. These are mostly whole pages but sometmes half pages, somtimes they are half blank pages. Typically they are advertising debt problems services or offering special deals on products. I have windows XP and I am using IE7. I run Ad-aware scan daily and remove cookies as recommended. I have Norton anti-virus; the latest scan showed no viruses. I also have installed Simply Sup Trojan remover. A general scan did not reveal any malicious elements. I also recently downloaded and run IObit Advanced Window Cleaner. The pops still appear. I read through previous forums about the possibility that this may be linked to Smiley software, which was earlier downloaded on our Windows Messenger. I removed this; the bannesr are still there. Any help in dealing with this will be appreciated. I searched earlier forums but could not find a similar case.
