I don't think a whole forum is warranted yet since there are only about 4 people max who use it ... what I think would be a good idea right now is to post them in the Techie's Lounge and sticky them in there. Then, when the security scares are over, unsticky the older ones.
The Techie's Lounge is a hang out place for all of the regular folks who visit Tech Talk. I'm not one of them. Therefore, it's not my call to decide what you guys want to talk about :)
I'm just suggesting that it would be a good idea to sticky the canned replies for current security threats because this way they'll be easily available to people who want to be helpers as well as people who want to self-help themselves and are looking for the fix.
I just recently learned that canned responses are responses that are already premade. So, they can scan a Hijack This Log, find the problem, and paste the solution (already prettied up with BBCode Tags and all, so it has bullets and color, and fun stuff) without having to type it over and over for the same spyware/virus problem. I think they are kinda sexy....
