Microsoft Chairman Bill Gates said on Tuesday the software giant was boosting security measures after six employees were exposed to a letter that had tested positive for anthrax.
"Obviously, like all companies, we are beefing up the various things we do to try and keep our employees as safe as possible," Gates said at a news conference in Tokyo.
Six Microsoft employees were exposed to the anthrax-tainted envelope sent to the Microsoft office in Reno from Malaysia. All six have received a clean bill of health, but the United States remains on edge after anthrax-contaminated envelopes were sent to media offices in New York and Florida.
