Yo all,

Ive had spyware guard for a while now, but it never seems to find any updates for itself.

The definitions have dated 22/01/2004 since I first downloaded it and every time I run live update it comes back with 'no updates available'.

Surely thats not right?

Im running version 2.2.0, its not blocked by my firewall or anything?

Yes you have the latest version. The reason for less frequent updates with SpywareGuard is that much of its detection abilities are heuristics in nature. (Basically this means it doesn't need a specific signature for every spyware it catches, simply an overall pattern or approach-used, which it can identify and then trigger off of.) So, SpywareGuard works for many of the newer versions of the same spyware installers even without adding "signatures" for them.

An update is made when there are new items coming out that are not detected that way.

To expand on what Fozzie said:

SpywareGuard does not require constant definition updates because its detection abilities use a heuristic (rule-based) engine. Normally, for an Anti-Virus product to detect a virus, the virus must have been seen before, analyzed and detection added to the signature update files. Heuristics are used since there are some families of viruses that continually change their appearance and it is not possible to detect every variant. Heuristics allows setting up a defined set of rules so if it looks like a virus, and acts like a virus it can be detected, even if the virus has never been seen before. SpywareGuard uses this same approach for detecting spyware. Further, SpywareGuard's strongest protection is its Browser Hijacking Protection, which does not any sort of definition updates.
