it was a post on the Yahoo Message Board, in between about ten thousand other garbage posts. Nobody even noticed before McAfee claimed it went viral.. Don't just copy anything this guy says.
Btw, what is this? Is McAfee watching his own stock price 24/7? And isn't it illegal for him to comment on share price movements on this twitter account? (you don't need to answer these questions, i know them already)
I noticed it only shows 96 likes and 23 retweets for the viral message. I thought when something goes viral it means everyone is passing the message around. I dont think thats what caused the drop if it only has 112 pass arounds.
