Anyone know what is the difference between “Normal” and “High” in the Web Shield? Couldn’t see any changes in the settings…
Technically there isn’t, however it is very customizable, if you are willing to do it manually. (URL blocking etc).

Why is there a “Normal” and a “High” setting then 
If there is no difference
Lars, every avast provider has this option - you can also change this setting for all providers at once (when “show more details” option is not selected). Maybe in the future even in webshield this option will have it’s special effect, but for now we choosed to provide the user with the possibility to finetune webshield manually via the Properties pages.
