Velmi dobrý antivirus. Byl jediný, který detekoval virus, zobrazující neustále reklamy. Analýza je pomalá, ale účinná.

Wish it were faster

Very good antivirus. It was the only one that detected a virus that opened ads to me constantly. The analysis is slow but efficient.
It is a good application that does a lot.

I am not sure

Avira did not find any viruses, but Norton tells that computer is infected with 5 viruses. Whom should I trust?
Horrible way to push all products in Antivirus
Windows User
So It not only uses all of resources but also installs spam softwares without uses permission also few browser extensions. They are problem now not the solution.
Scammers

I worked with them , by mail, for 1 1/2 months with no results to my error code & I was unable to us4e my anti virus program. I finally had to delete it & download another product. And of course no refund. Terrible service !! And no working phone number !!!
Makes your PC very slow.
Windows User
Make your PC very slow. Nearly impossible to uninstall. I might have to reinstall OS to get rid of this nuisance.

They ruined it. It Became bloatware. Who the hell ask them to put all they have in something that expected to be ONLY Antivirus program. They don't leave me the choice to opt-out things that I don't need or want, like VPN (I'm using a different one) or Game Booster (I'm not a gamer) and Optimizer (easy way to destroy your system). So I decided to say goodbye to them. Sorry.
Ignore Don't Work
Windows User
Avira ignore feature is a mess that doesn't really work. If you are IT developer you should really keep away from it.
Accused As A Cyber Theft Criminal

Their Free Download Version Was Infected With PUP Malware That Forcefully Tries To Install Onto Your PC! Microsoft Had Blocked That One File Installation From Happening With Their Smart Screen Protection Filter!
Including, That “CBI Avira” Had Fraudulently Charged Me $100 For “Recurring Withdrawal” On 06/29/2021, But This Avira Company Had Quoted Within Email That They Did Not Have This Kind On Information On File! Now, I Am Asking For My Financial Assistance Group As To Resolve This One Financial Problem!
I Do Not Want Avira To Ding My Card Again!
