=== Patent lawsuit ===
In 2008, [[Barracuda Networks]] was sued by [[Trend Micro]] for its distribution of ClamAV as part of a security package.<ref>{{cite web |url=http://www.linux.com/feature/126851 |title=Trend Micro patent claim provokes FOSS community, leads to boycott |publisher=Linux.com |date=2008-02-11 |access-date=2008-02-12}}</ref> Trend Micro claimed that Barracuda's utilization of ClamAV infringes on a [[software patent]] for filtering viruses on an [[Gateway (computer networking)|Internet gateway]]. The [[free software community]] responded in part by calling for a [[boycott]] against Trend Micro.
