Microsoft isn't too happy with the results of a recent test that found fault with its antivirus software.

Stuxnet, the sophisticated computer virus that attacked a nuclear enrichment facility in Iran two years ago, also inadvertently infected Chevron's network.

Reportedly created by the U.S. and Israel, the highly destructive worm was designed to infect Iran's Natanz nuclear facility.

The oil giant discovered the malware in July 2010 after the virus escaped from its intended target, Mark Koelmel, Chevron's general manager of the … Read more
