BT Busts Zombies

Silicon reports that BT has launched a new 'spam buster' system which it hopes will clamp down on junk email within the telco's broadband network.

The Content Forensics system, which was developed by StreamShield Networks, is designed to combat professional spammers as well as botnets - rogue software that infects computers and transforms them into spam-generating networks.

According to Gartner, 80 per cent of email on the internet is spam, while security software maker Trend Micro estimates that around 6.5 billion separate items are sent per day
