Slowly but surely, internet security has become the top priority for anyone using a PC in the modern era, and antivirus programs keep evolving to deliver safety to their users.

Avast is a popular antivirus product that introduces what the development company calls a “Web Shield” – A feature that improves the user’s browsing safety in real-time.

This has proven itself to be a very useful addition to the already-existing traditional antivirus program Avast has been developing for years, but it sometimes fails to activate, which leaves users afraid and wondering what the problem could be.

Luckily, we’ve analyzed the situation and can help you solve the problem for good. All the answers are in the guide below, so without further ado, here’s what you should know.

The Problem Explained

Upon accessing the features menu in the Avast antivirus program, users can “toggle on” the ones they require. On this list is, of course, the Avast Web Shield.

However, there sometimes seems to be a problem when users try to activate the Avast Web Shield, and it just fails to start. This problem is confusing as there aren’t any error messages accompanied with it, nor an explanation about why this feature is not working as intended.

Because of this situation, users are afraid to continue browsing the internet as they feel vulnerable to threats without the Avast Web Shield.

Luckily, we managed to fix this problem using the multiple proven and tested methods below, so let’s take a look at them.
