SETI@Home A Security Threat, Says TVA

evenprime writes: "Richard Chambers, the Inspector General of the Tennessee Valley Authority, has declared that employee use of SETI@Home on TVA computers compromises computer security. I'm wondering why using SETI@Home on PCs with access to the internet would be a problem. As cheap as PCs are, you'd think that TVA would have separate internet/email PCs on every desktop, and so no form of malware could affect their machines used for power generation and/or managment."
