No sirve, no muestra datos de las webs y se queda colgado por largo tiempo para la configuracion

There is no point in getting any antivirus like avast because you should already have one installed onto your computer called windows security

Avoid this kind of useless AntiVirus extensions that in facts can spy what you are looking on the internet, it's just collecting informations on you to profile you and similar customers to finally target ads/products/services. That's desguished spyware in counterpart to provide you a pretended nice service for free.

And just about the service provided: this kind of extensions (lots of similar exist like this one) can modify the webpages on-the-fly and also can censure some parts or search results to guide you to buy to a specific shop/information site/etc... instead of a concurrent. And guess who is paying the extension editor to do that? Sellers? Governments? ...?
Just look at what this extension is requiring at the Permissions part...

Mind again before adding browser extensions!

WILL NOT UNINSTALL!!!!

Da errore facendo anche sono una ricerca su google

avast is trash

pożytek niewidoczny, utrudnienia dokuczliwe

Have been caught selling user data per verified internet reports. Have had intrusive default behavior from Avast Security Suite in the past with Shopping component automatically looking at web purchases i was making and offering me "price comparisons" before I turned it off. Hard to trust at this point.
