I am trying to find a download for ClamXav 2.5.1 for Mac OSX Leopard PPC

I have an old PPC PowerMac G4 MDD.

I am trying to find a download link for ClamXav version 2.5.1-- the last version that is compatible with PPC Macs

running Mac OSX 10.5.8 Leopard.

So far I have no luck finding it on the ClamXav developer website.

But I found a download link on Mac.filehorse.com, but is Mac.filehorse.com a safe and legit website

to download older Mac software?

Any help or advice would be appreciated.

Thank you.
