McAfee Finds Security in Foundstone (The Motley Fool) The Motley Fool - Shortly after we came back from our big vacation overseas in May, my Apple (Nasdaq: AAPL - News) PowerBook was hit with a computer virus. I can't tell you which one, but it was enough to cripple my Microsoft (Nasdaq: MSFT - News) Office for the Mac software. Symantec's (Nasdaq: SYMC - News) Norton Anti-Virus found the bug, and then eradicated it by exterminating my entire in-box. (Thanks, guys.)
