This notice is to inform you that effective June 1, 2016, ClamAV 0.97 (and all minor versions) is no longer supported in accordance with ClamAV's EOL policy which can be found here:
EOL for ClamAV essentially means that we will no longer be testing against that version when we write signatures, and we may break something with a future release. So, while signatures may work past June 1st, we are no longer testing that configuration, so you are on your own.
Please upgrade to the newest version of ClamAV, currently at 0.99.2, available for download.
Thank you for using ClamAV!
