Err..., where's your Firewall and Anti Virus protection?
I use Norton AV and Sygate Pro Firewall. I also use Spybot, Ad Aware and Spyware Blaster. I used to have A2 but apparently it's not all that, as it doesn't protect against all trojans. I then went through a whole load of other Trojan scanners, but in the end I decided not to bother, as my Firewall and AV should be enough, and there are online Trojan scanners which can be used once in a while. I have EndItAll2, which I sometimes find useful, but having come a cropper with one of the registry cleaners I don't use any of them now. Not sure what Stinger is, and can guess what Diskfrag does, but haven't used it. Used to have Cookie Wall for IE, but now I use Mozilla, which has it's own built in Pop Up Stopper, as does IE if you have XP with SP2.
