Today we detected via our monitoring stations a small number of emails generated by the mass-mailing worm W32/Forbot-FG. This worm was first detected in 2005 and is pretty much your typical bot with backdoor Trojan functionality and spreading capabilities either by exploiting network vulnerabilities or mass-mailing.
However, this case highlights the fact that old malware will always have a life and be an Internet nuisance with even just a single computer infected. It also highlights that security software is not just for today's, or this month's current crop of malware. Security software must continue to protect and guard against threats going back years and every day, that number just continues to grow.
