I've swallowed my pride and installed Avira Antivir 3 for UNIX. It was a bit of a faff to install but once done it was groovy. However there's no GUI for it so avoid if you're scared of the CLI.
It's really, really good and bugger is it fast

(I'll post a howto if anybody wants it)
====================================
Ok here's how I installed Avira Antivir on my openSUSE 11.2 system.
Requirements:
- GCC Compiler
- Kernel Sources
- Dazukofs kernel module (pref. version 3)
If these aren't installed by default on your system, go to your package manager to install them - they're all fairly standard.
===========================================
Go to Avira and download the AntiVir (UNIX) package.
Copy the archive file antivir-workstation-pers.tar.gz to the /tmp directory- jim@linux:~> cd /tmp
jim@linux:/tmp> tar -tar -xzvf antivir-workstation-pers.tar.gz
This will upack the archive to a folder in /tmp called antivir-workstation-pers-<version> according to what version number you download.- jim@linux:/tmp> su
Password:
Instead of typing out the name of the folder, type the first few letters and then press tab - the full name should then appear- linux:/tmp> cd /antivir-workstation-pers-<version>
linux:/tmp/antivir-workstation-pers-<version> >./install
Press enter to view the terms and then press q to exit.- Do you agree to the license terms? [n] y
