[QUOTE="BoraMurdar, post: 812518, member: 2291"] Microsoft has every possible mean to make it the best optimized, fastest AV solution on the market with all compatibility advantages and telemetry but it simply doesn't. I mean, everyone can test the performance by just downloading 10 random installers from Softpedia and put it in one folder. Then open Task Manager and open that folder. You will see the spikes in CPU and Disk usage. Scanning the folder by right click scan and opening it again doesn't improve accessing times or improves it insignificantly. So Windowd Defender caching is not something Microsoft can be proud of, especially in 2019. Scan upon execution is what Windows Defender needs in my opinion. [/QUOTE]
