Grandma - my take is this:
Anything before MSIE 6 is fake (or otherwise rejectable) UNLESS it is one of the very few mobile UAs - best dump them all now that mobile devices are more "modern" with different UAs. MSIE 6 is obsolete and many can be dumped - although beware: obsolete Windows 2000 cannot support anything later than MSIE 6 (which does not worry me because we use firefox anyway and I personally use Linux for browsing (and most other things)).
Anything Opera before V9 is suspect (can't comment further as I rarely use it and then on linux).
The moz/4.79 looks like Netscape, which I don't think anyone uses now. Your example purports to be running under Windows 2000 (NT 5.0). In general, I would dump it.
bork is rejectable in my opinion.
Multiple MSIE versions in a single UA are usually due to bad updating but I would kill them as being too old - most recent UAs seem much cleaner unless some stupid "toolbar" has been installed.
funwebproducts should be eradicated but sadly I still see a lot of "good" visitors. I'm tempted to tell visitors to the web page how stupid they are - but then, I would like to do that for google UAs and toolbars as well. In all, I think it's their funeral (and likely to be so with funwebproducts) but not usually a bot (except where the UA rotates).
There are a couple of useful sites for determining the more popular UAs:
user-agents.org (bots and browsers)
zytrax.com (mostly browsers)
