Hi all. the last couple f days I've seen the overall Mh/s amount diminishing (mining ETH at nanopool). I moved from an average of 192.4Mh/s to 190.7Mh/s. (x7 rx570)
That is because more people are mining ETH do to the rise in price, so the difficulty is also rising and your effective hashrate drops.
The only significant issue was that Windows Defender (windows 10) all of a sudden decided that EthDcrMiner64.exe was a severe thread and put it on quarantine. I fixed that setting the file and the process on the exclusion list. I may be wrong, but I'm pretty sure that the decrease on speed was before the incident.
I don't know if the incident is related to the lose of speed, or some other external factor is affecting production, and I'd appreciate any input on the problem.
Setting an exception for any miner in an AV is normal. If your miner gets blocked, it does not affect the speed, but just prevents you from restarting it.
