Clam's product is free, by the way -- you rarely hear about proprietary, for-pay or for-fee programs issuing blanket challenges.
The company's AntiVirus Fight Club approach to getting the word out strikes me as both confident and dismissive at the same time.
Confident because they know their product and believe in it. Dismissive because they know their competitor's products and don't.
Sound familiar? Sure it does, anot just because it's redolent of the open source philosophy. It's also redolent of that classic SMB mix of faith and arrogance that's served so many businesses so well.
See you after the fights.
