Title said it all. My download speed is literally measured in kilobytes while BitDefender is active, as soon as I turn off the protection shield it comes right up.
I tried reinstalling BitDefender and even reinstalled Windows but nothing changed (also reinstalled/updated my wificard drivers, this problem happens with the internet cable plugged in aswell).
The thing is that if I disable Windows firewall entirely half of my download speed comes back. What should I do? P.S. I am using BitDefender free edition with a fully up to date Windows 10 copy
