My OS is windows 10 pro ( 1903) with latest updates.Not seeing any speed issues here. I'm sure the AG team will need info, e.g. what Windows are you using? Any antivirus/antimalware software? If so, what? What web browser(s) are you using? How fast is your connection usually?
Thank you for your advice. I excluded applications each other and i think it is now better. concerning WFP driver, is not important to turn it off.@Omarzwy
To get started, you should add applications to each other exceptions (AdGuard and Kaspersky).
You should also try turning off the WFP driver and checking the connection speed.
Please send screenshots from these two sites fast.com & speedtest.net (with protection on and off).
