Avira Antivirus Engine: Update to new version required
As you may know, Sophos offers two anti-virus engines for the SG and XG firewalls. One is Sophos’s own antivirus engine, and the other is Avira’s engine.
This interaction will not change in the future, but Avira will discontinue support for an older version of its scan engine on 31 December 2019.
What you need to keep in mind
Sophos has already responded to this announcement. The XG v17.5 and UTM 9.6 versions already use the new Avira engine.
Anyone still working with older firmware versions of these products and using the Avira engine will simply have to upgrade to at least one of the above versions by the end of the year.
Cyberoam products now use only the Sophos scan engine, so all Cyberoam customers will need to upgrade to version 10.6.2 or higher.
