Boycott Trend Micro Basically, Trend Micro is suing Barracuda Networks over their inclusion of ClamAV on Barracuda's firewall device. Removing AntiVirus software from network firewalls is a "bad thing" - you think spam and viruses are bad now? Just wait to see what will happen if Trend Micro succeeds. This is also yet another illustration of how the US Patent system is seriously flawed.
