Same Company
Windows User
I don't understand how Norton could be competitor as Norton, Avira and Avast/AVG are now the same company.
Scammers
Windows User
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.
effective security for home
Android User
I liked the review, the Hungarian and the English one
it is a detailed one
I have used some AVs but Avira is the perfect one for me cuz of CPU usage and I use it every day
best free antivirus but I hated the ads so I bought Pro
I must recommend it for home security
I couldn't write much about cons..
its con is that it is less lightweight than the older versions
but in 2021 you must bring more features and services into the AV for your effective protection..
the password manager is an innovative thing maybe I will try in the future

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!

No protection against ransomware in Avia Prime, even though Avira claims "Ransomware Protection is on." Since October 2020 I am experiencing ransomware attacks, and as of April 2021, Avira is still not realizing that their software has a problem. Avira Support Team's response is limited to computer-generated correspondence and sometimes wrong advice. I have seen other Avira customers on Facebook complaining about ransomware attacks. I started looking around for better antivirus programs.
Very Good Antivirus
Windows User
It has protected me a lot and I never got a virus. For my personal choice, I think Avira is worth it Antivirus. Because I did some test on Virtual Machine and it detected many Viruses. I also watched some videos about Avira. So I recommend it. (sorry for bad grammar )
