Antivirus mode on server
We do not recommend to use antivirus software on server in automatic mode.
If you want to use any antivirus, you should install the software and then disable it, for example windows defender setting (Figure 1).
You can run scan when you do not have customers. You can just chose any scan option and then click on "Scan now" (Figure 2).
Note: If you use automatic scan, it can start lagging when customers are playing.
