I have set up a local Elasticsearch instance with two nodes. I have Logstash sending documents every 15 minutes. Today one of our IT members warned me that there are some "viruses" on the Windows server I was given. When I checked 8 .dim files in the indices of one of the nodes have been identified as "a variant of leronim.512 virus". I have searched for a similar post on the discussion forums but it seems like there aren't any topics related with ESET. Below is a screenshot from the virus protection.
Has anyone seen a similar behaviour?
Edit: I know they are not viruses. Hence, I used quotation marks.
