Recently we have seen a couple of instances of updated AV software quarantining the eVo TD Service as a precaution.
Obviously it is not a virus but some of the repetitive file access projects particularly around PDF editing and optimisation look awfully like it.
We always state that the services, Program files, and Program Data folders together with any transactional folders should be excluded specifically in the Server AV configuration, or trusted.
The quarantine of a service being triggered simply stops the system, but even real-time inspection of files being read and written by Formate could significantly impact throughput due the server loading and delay inspection of the files by the AV suite.
