The proliferation of virus is down to people not taking basic precautions such as installing anti virus software, and not opening suspect emails - especially those with attachments.
You will probably find it is not a bot that is trawling the site for email addies, as most if not all bots do not support session id's - which php based forums use. More than likely it is a site user who has the virus, and you happened to be in their address book - the virus sends itself to all addresses in the infected PC's address book, and everyone that opens it, if not protected by anti virus software, is infected and the process starts all over again.
Install anti virus software, keep up to date with virus definitions, and do not open suspect emails, or emails with attachments that you are not expecting - simple innit.
plus good old for a nice powerfull free firewall
