AV Scan Error: "Could not check /var/lib/lxcfs/..."

On the first scan after install (on a newly installed & configured Ubuntu 16.04), I received a whole slew of errors like the following:

"Could not check /var/lib/lxcfs/cgroup/pids/system.slice/tasks (virus scan failed)"

All of them begin with the same path("/var/lib/lxcfs/cgroup/") and branch from there.

At first glance this seems to be an access issue, but I installed SAV as root and ran the scan as root as well, so I don't know why there should be an issue. In fact, I don't even know if this is anything to be concerned about.
