This was posted by the administrator on the Wilders Security Forum a few months after the last update. I think its a semi-official, though dated, statement about why updates are sparse.

Re:Having problems with SpywareGuard Updates
--------------------------------------------------------------------------------
Hi amoeba,
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.

I suppose the heuristic scanning means the program still has some value but things do tend to lag behind if you go 26 months (and counting) between updates.
