[QUOTE="SeriousHoax, post: 914314, member: 78686"] Yes that's common for AV with HTTPS scanning. I had seen more or less similar usage for Kaspersky, Bitdefender, ESET but Bitdefender use less on average as it doesn't do HTTPS scanning on most trusted pages you would visit regularly but one thing I have noticed that Bitdefender scans scripts really early. Even earlier than adblocker extension like uBlock Origin while Kaspersky don't/can't scan scripts that are blocked by uBO which is the expected result. I forgot how ESET does it. Now comparing CPU usage while browsing with Windows Defender which doesn't do HTTPS scanning is much lower. With "Network Protection" enabled via ConfigureDefender, both "Antimalware Service" and "Network Realtime Inspection Service" use 0.5% CPU on average so 1% usage combined. This may result in longer battery life on laptops if the main thing the user do is browsing. This is my basic observation only so that's why I wish there were professional tests which showcase this impact. [/QUOTE]
