Folks, just wanted to bump this back to an active post to be sure as many of yall as possible read what Anthony had to say.
I PM'd Anthony today about the influx of real weird User names as newly registered users we have been getting in the last few days...ID's alot like the one that the virus link came from. Anthony feels like spam programing has figured out how to get around the "security" in place in the registering process. Right now, the only alternative would be to go to a system where it would require administrative approval for every new user. At this point Anthony does not want to do this and I'm sure any potential new user would not want it either.
So, as Anthony said earlier, watch yourselves

Thanks!

I also own a much smaller PHPBB discussion board and I became inundated by spammer/robot registrations. I did a "one-two punch," and made the problem disappear.
I did two mods:
Delete user mod
(to delete the unwanted posters)
Registration Authorization Code "RAC mod"
(requires users to enter a special code to finish the registration.)
The second MOD stopped the frivolous registrations by 100% I was getting 10 to 20 new registrations a day (all spammers) and this has stopped completely.
I opted for admin approval of all new user registrations. With the RAC mod the I'm no longer inundated with emails.
