Unless you run into a problem where you need to post a log, your archive is just so that you have something to compare what processes were running when things were right to what's going on when there's a problem. I don't make new logs very often, but then I don't make very frequeent program additions/removals.

If you need to post a log, you'll want to update and run Ad-Aware and Spybot, and update Hijack This, to be sure you have the latest versions of them all, before you make the log that you post. Since the only thing you get when you run it is a log of what processes are open on your machine, there's not much sense in making the running of a new log a regularly scheduled thing. If you think of it when you've installed or removed a program, a fresh log won't hurt anything.

The main thing is to have an idea of what it is and where to get it IF/WHEN you need it for something major. For that, any old logs you've made won't be of interest. You'll have to run a fresh one to post.

Secondarily, you may be able to get some clues for fixing simpler things if you have a reasonably recent log to consult (and if you remember where you put it when it might be useful). You'll need the program handy to run a "current log" to compare with the archived one. Anything "different" between the two logs is "suspicious," but of course you still have to figure out if it's "significant" and then find a way to safely change it to see if the problem gets solved.
