I use Zone Alarm, which has worked well for me in various versions for at least 10 years. However, it is my Microsoft : "Live One Care" that has been telling me it detects, then deleats a :"Trojan redirector"
I've not really had any problems with Live One Care. I've had no virus, no pop ups even. Although I mostly go to CoH, us.army.mil, and my Yahoo Fantasy Sports, and my email accounts, oh and the Royal Navy webring; none really prone to viruseskeyloggers, or worms.
Does that help in identifying if there is actually a Trojan lurking on the Titan Network main page?
