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.

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.

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 Sad.
Windows User
Very Sad I paid and the the software does not open and very difficult to get help. I will have to change the virus protection Software
Avira is SCAM
Windows User
I used Free Avira for years and everything was fine but lately, it just doesn't work. Real-time protection is always disabled and when I click on fix issues it always takes ages and doesn't show anything. I tried to reinstall Avira 4 times over the course of a few months on my new laptop, but no longer. I am going to use Windows Defender now. Any idea why this might be? Can I have a virus that disables Avira? When I try to uninstall it, it says that Avira Antivirus is using it but I cannot uninstall that one either. I deleted all the Avira files from the computer but Avira made sure that it will remain on my laptop forever I guess :D
