I installed ESET NOD32 10 trial today and I made a SysInspector snapshot. To my surprise, it showed a ESET module and Windows Memory Compression process as "5:unknown". It also shows clrcompression.dll in the Windows Store apps as "9:risky". Flagged ESET module "em042_64.dll" is related to Network Protection. clrcompression.dll were from Solitaire and Photos app. It's a newly installed Windows system setup on 19th. I was running Windows Defender on it earlier.
