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)
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.

EDIT: I forgot to mention, but the average weather temp has increased to +30 Cº increasing GPUs temp +2 degrees approx. (the max values being 71, 71, 69, 59, 67, 65, 68)
