Blocking ads using Mikrotik

Hi, I’ve followed some guide for blocking youtube and google ads using firewall with this command
add action=drop chain=forward comment=“Drop sites from Adblock” disabled=yes
dst-address-list=adblock

My issue is when that I can’t access google.com and youtube. I tried with adding these websites in static DNS, but CPU is getting at 90% almost all the time. Router is RB951G.
What list should I use and where to put it in the Mikrotik? Thank you.

Maybe this would be a better idea… use it as your dns server
