The latest about:blank trojan from the dix at CoolWebSearch, seems to be absolutely invincible. Even the author of HJT and others have thrown up their hands. The latest form of MS antispy is ineffective, as well as all the usual spyware like ad-aware, ferrit, spybot s+d etc. etc. etc...It seems to be combating the very programs set up to delete it and replicates itself as soon as you go on the web. It would not even allow me to log on to tek-tips!!! My final solution was to partition the hd, install new os and abandon IE as a browser for now. Basically a new pc on the old hard drive.
