I inquired about this log entry on the clamav-users list and received acknowledgement that they are aware and will fix it.  Functionality is not affected.

I just received notice of the release of ClamAV 0.99.4.  Details here:

 It's a little bit buggy ... [8-)]

WARNING: Your ClamAV installation is OUTDATED!
WARNING: Local version: clamav-0.99.4 Recommended version: 0.99.4
DON'T PANIC! Read http://www.clamav.net/documents/upgrading-clamav

I noticed that too.  I should have tested it BEFORE announcing its existence.

No, please continue with the update information!

Here it just looks as if the string "clamav-0.99.4" is wrong, because in the previous versions there was always "0.99.x".

By

the way: I also find a version with OpenSSL 1.1.0 support (0.100.beta),

but the OpenSSL version used there is very old (v1.1.0c I think)
