ContentBody{} FormattedBody{value='

 Problem

Ubuntu/Linux’s AppArmor may prevent access to file or directory causing Anti-Virus scanner to throw an error.

 Solution

Few ways to prevent this error:

1. Disabling AppArmor

   1. sudo systemctl stop apparmor.service
sudo systemctl disable apparmor.service

2. Set AppArmor to complain instead of denying access

   1. apt-get install apparmor-utils
aa-complain /path/to/your/scanner (e.g. /usr/sbin/clamd)
