Anthrax: It's a virus even your computer can catch

The widespread paranoia surrounding anthrax has seen the return of a computer virus that arrives in users' inboxes purporting to offer invaluable advice on the killer germ.

The self-propagating worm is carried in an email which is written in Spanish, with the words 'Antrax Info' in the subject line, according to a report on Reuters.

When activated the worm will email itself to every address in the users' address book. However, according to anti-virus vendor Sophos it was around long before the current anthrax-related scares and major anti-virus vendors already protect against it.
