QOTD - Schneier on AntiVirus

Antivirus software is neither necessary nor sufficient for security, but it's still a good idea. It's not a panacea that magically makes you safe, nor is it is obsolete in the face of current threats. As countermeasures go, it's cheap, it's easy, and it's effective. -- Bruce Schneier, Chief Security Technology Officer of BT Global Services
