Surely it doesn't take a block list for you to stop visiting that site ?
It doesn't take porn to land on a site that portends to supply you the information you want from google. And it's a bad idea to commit these to memory. Google returns what it returns. The number of sites I visit are legion.
I'm supposed to remember the good from the bad?
There is no such one click button function - If you can't trust to memory:
You can add the site to either your firewall (?), HOSTS file or add it to the Additional Protection, Site Blocking, URLs to block.
Yes. For 15 years I've been maintaining a modified hosts file. Further, I know how to do add it by hand in other ways. The problem is that there really should be a quick "block in the future?" popup, or similar option. Avast is a powerful tool providing ways of 1. detecting malware and blocking malware, and 2. blocking websites.
That they don't connect the two concepts quickly seems odd. RIGHT AT THE DISCOVERY of the malware is WHEN I KNOW FOR SURE that I have found a website to block.
