Hi could be silly but i have noticed that many antivirus do scan an excessive number of files for example on the same machine , clean install of windows 10 , 8 and 7 i have installed eset smart security 9 last version and tested all the settings of eset smart security 9 are the same ,and same hardware real time scanner same settings , extensions ->scan all files Disabled . scan extensionless files Disabled i said that are clean install of w10 ,8 , and 7 , in short the only software installed is the antivirus well i did boot and kept my pc idle for few minutes , 10 minutes (i have done the last test 1 hours ago) eset scanned more then 3200 files and continue to scan ,even it have scanned few minutes before under w8.1 and w7 around 600 files ok , i said it's sillly question but the point is have you noticed an eccessive antivirus activity ,real time scanned files under windows 10 compared to w7 or w8? it's not related to eset and windows 10 , but it's related to windows 10 and another antivirus thanks
