As far as I know, Avira has also discontinued their linux product.
We have augmented clamav with the sanesecurity signatures.
I just read about the interesting YARA project and am looking into 
adding these rules also.

Also we block .js and the old microsoft office formats.

Up to now this seems to work quite well, we do not see anything relevant 
get through.
On our customer's mail servers we partly run the kaspersky mail scanner 
which works very well.

HTH, Jakob
