We also use Trend AV for Windows servers (Officescan) and ServerProtect
for NetWare & Linux as well as ScanMail for Domino.  I've been quite happy
with their suite of products.

"In ServerProtect for Linux 3.0, the Kernel Hook Module (KHM) is open
source licensed under General Public License (GPL). This provides users
the flexibility to recompile the KHM when they upgrade their Linux kernel
versions without waiting for Trend Micro to release the official KHMs."
