When I have a piece of software that must go and the uninstall didn't make it go away I use 2 titles to help. One is fairly easy the other is like a hammer and chisel so you must know which to delete.
2. Hijackthis from http://download.cnet.com/Trend-Micro-HijackThis/3000-8022_4-10227353.html
Hijackthis is for more than spyware use, I use it to delete items that I want gone.
I have a Compaq Presario Desktop - this came with Vista Home installed. I Installed XP as a dual boot on this machine. We use the XP for 90% of the time. My problem is this perpetual error message popping up on the screen. I just cannot seem to be rid of it. despite not having a date card installed - at least I don't believe so !-and my screen res is above 800X 600. Help on this anyone .
