The Heuristic Tools
Of these utilities, Hijackthis, Spyware Guard, and Prevx1 are the barely ones which exploit some type of heuristic discovery. These utilities are all rather unique, and are all quite equal in efficiency. Spyware Guard and Prevx1 present real-time security. They check the computer, and at any time an action that could be recognized with spyware happens, they warn you, try to avoid it, and could be used to counteract the danger. Prevx1 is almost certainly more commanding than Spyware Guard, and Hijackthis is perhaps the most functional in determining if you are by now tainted with spyware. Spyware is not easy to contest using heuristic software. Normally, authoritative signature scanners will be more precise and successful at shielding you than heuristic detection, but as a foolproof, heuristic detection is the best alternative.
