The AV product works as advertised. I had no issues with it.
The Phantom VPN Pro, however, product does not work well. In fact, issues I experienced required that I uninstall the product and re-install it from the Mac App Store several times. (Yes, I ma running on a MC with OS X 10.13.6 .)
But the worst issue was the quality of support received from Avira's so-called Customer Service Engineers. I am in North America in the Mountain Time zone. I am calling before noon and the number for support of Canada and US customers connects you to Germany. I was having an issue trying to upload a file to their FTP server in support of a month-old ticket. When I reached a person on the line, I was informed not his call:
1. That he didn't have MacOs X knowledge or experience.
2. That he could not refer me to anyone at Avira with such knowledge or experience.
3. That he had neither a supervisor or manager to whom I could speak to try to get some kind of support.
4. That the purchase of license was analogous to purchase of a car. Avira could not tell me how to drive it!
5. By implication, purchase of a license from Avira did not include support and I was basically on my own.
I have never had a CSE ever speak to me in this way. He even offered a complete refund for their VPN Pro product which I gladly accepted. When I indicated that I would not want to continue with their AV Pro product, he offered to refund that as well. I have accepted both refunds.
In over 40 years of working in IT, I have never encountered support from any company...and I've used a number of them. I have certainly never purchased licenses and received such dismal support.
Consequently, I cannot recommend Avira to anyone.
