How to immunize your computer - viruses can be beaten at their own game
Malicious computer viruses could be stopped in their tracks by immunity software that spreads faster than the virus itself, says a team of computer experts from Israel. Their proposal relies on setting up a network of shortcuts through the Internet that only antiviral programs can use, allowing them to immunize computers before a virus arrives.
Eran Shir of Tel Aviv University began thinking about the problem when the infamous Blaster worm spread across the Internet in 2003. "It really got me annoyed," he recalls. "Conventional antivirus software just couldn't keep up with its spread.".... "The software companies just regard the Internet as a sophisticated FedEx service," Shir says. "Our focus is to immunize the whole network, not to clean individual computers or fix what is already broken." This means using the malicious code's own techniques to distribute immunity. news @ nature.com - How to immunize your computer - Model shows viruses can be beaten at their own game.
