I want to thank everyone who has brought to our attention the shortcomings of ClamAV at this time. We are aware of the issue, and we are diligently researching options. For SM 14, at a minimum we are planning on updating the packaged ClamAV to the latest version. As stated, we are also looking at possible replacements, if necessary.
Webio, I have added your suggestion of adding command line scanner results to the SM virus statistics to our features request list. Obviously, this option would have to be configurable because the various products do return different results.
I am changing this thread from a Question to a Problem and marking it as Being Fixed.
