especially as this is the only way I can manage my miners remotely. it is beginning to cost me money.
You do something wrong. I have no problems on all of my rigs (around 40 rigs), all work normal. Deactivate windows defender complete, if you have problems -> must be done in the registry -> i have done this at the beginning of my mining journey.
I did nothing wrong - windows keeps adding it back as a trojan. I am not deactivating windows defender completely so that my system is 100% open and vulnerable - no thanks.
When this happens, have you tried to add Exclusions to allow specific processes and folders?
