My Windows ME PC had recently been invaded with lots of icons for porn sites etc. which I seem to have removed using Spybot and Ad-aware but there is one problem remaining - there is an almost circular red icon on the right of the taskbar which does not show any info with the mouse cursor and cannot be deleted. On boot-up a browser window appears which I cannot close and is recommending me to use "antiSPY" to remove it. After several minutes, I can close the window but is reappears a few minutes later. Any ideas?
