News: We’re Losing the Virus Arms Race

This week’s New Scientist confirms what readers of this blog already knew about the growing imbalance in the virus arms race. Antivirus specialists, the mag says, are fighting a losing battle against malicious code like viruses and worms. Research undertaken at Hewlett-Packard’s labs in Bristol, UK, is the first to evaluate the effectiveness of antiviral software. It shows that the way we fight viruses is fundamentally flawed, because viruses spread faster than antivirus patches can be distributed. By the time the antivirus software catches up, the damage has already been done.
Hewlett-Packard researcher Matthew Williamson designed a computer model to mimic the way in which viruses spread, based on a model that tracks the spread of biological viruses. He then introduced parameters to represent the way the antivirus software responds to this spread. He found that even if a signature is available from the moment a virus is released, it cannot stop the virus spreading if it propagates fast enough. Should we be worried? Yes.
