There should be a workstation edition of avast for Linux coming shortly. And it will likely have a free Home variant.
I'm not sure about BSD, though.
BTW if you only need the command-line scanner, you can use the one from the Linux/Unix Server edition. The command-line scanner works even without a license file.
Hope this helps,
Vlk
Thank you very much Vlk, that does indeed help, what i need is a cron jobbed scan and that is enough for me, system wide security is set to a level that is good enough so all i really need is a simple scan of home folders (should be quick) and a system wide scan about once every six months or so (after major updates).
Now, i only have a couple of more questions, thank you for your patience with me.
Where do i find the download for the on demand command line scanner and how do i get the definition updates?
I don't need instructions, just an adress to where will be fine.

Thank you.
