What is that add-to-post virus . . . .

. . . and how to get rid of it

I searched around for about an hour, and remember seeing this here at one point. There is a virus that, when someone posts on a php forum, it adds spam text to their post, like

example.com :-)
example.com :-)

They can edit it out, but every original new post or reply drops it in.

I know someone who has it and can't find the links to the description. It's not me, really. :-)

Possibly, but I suggested he run AdAware and it killed it when his AV software did not. So I'm guessing it was something else? The posting effect was the same though. Thank you!
