Has anyone used this program from PCTools? I've read the reviews and most appear to be positive. On the other hand I have also 'heard' that it's a resource hog and doesn't play well with the registry. Then again, the person that told me that couldn't say what it does to the registry!! One more thing, does anyone also use the firewall from PCTools? At present, I'm using Comodo's firewall, but since they no longer support, or update, the version for my OS (Win2000Pro) I figure it's about time I find another one. Okay, back to "Threatfire." I'm currently using Avast AV, Spywareblaster and SB-Search & Destroy and just thought it would be a good idea to maybe just another layer of protection. Especially with all those idiots out there with no lives, sitting behind their computers trying to make other people's lives miserable!! Any opinions of those two peices of software? THANKS!!!!!
