What are the advantages of using an ad blocker?

Having an advertising blocker installed in our browser gives us many advantages, since in addition to being annoying and invasive, it compromises our private information by having a great possibility of containing malicious software within its deceptive windows. So using a blocker we will achieve:

Ad blocking

Blocking the ads brings us many benefits, the biggest of which is that we avoid exposing ourselves to this unwanted content and that also makes the loading of the page we want to visit slower , forcing us to wait for all the ads to load to be able to show us the true content of the page.

Script management

A Script is a command line that obeys the application that executes them, the scripts can be programmed to make changes on our computer, open new pages, click on other ads, they can even read all the information on the page we visit and As if that were not enough, there are also scripts that are capable of reading and storing the personal passwords that we type on our computer or mobile phone. Normally, when we visit a page that contains advertisements, they can contain these scripts that can cause us great problems if we are not able to control them.
