Hi! Does anyone have any information on any issues that might incur if an AV program doesn’t exceptions for DM files/folders? I had an experience with Symantec where it had a problem with some DLL files but if anyone has some more technical information that would be great. Thanks!
Hi Luis,
Two things can happen. First of all, the antivirus can consume more system resources by scanning log files and database files which all change a lot on a DataMiner node. Secondly, and this is more worrying, the antivirus can inject their DLL in to our processes. In case of Symantec, that would be UMEngx86.dll.
The consequences of the DLL injection could be a lot of different things, and others might be able to give more examples, but I’m thinking about slowing down certain actions or even completely blocking them. This can result in RTEs (runtime errors) or memory leaks, and it can even cause crashes of threads or even complete processes!
Because of the nature of the DataMiner product, we do have a lot of network communication, and therefore an antivirus, especially with heuristic or behavior analysis, inside the DataMiner processes is not a good idea and needs to be avoided at all times.

Not sure if it is relevant in this thread, but I also heard about situations where there was an issue with the AV scanning all in and outgoing network traffic. And as this can be quite considerable for a DataMiner node, this causes the AV to consume a lot of CPU capacity.
