I don't see nay BB or antiransomware module in avira
I wouldn't doubt they have a anti-ransomware module but I'm betting it's just not very effective. Never seen any kind of behavioural detection by Avira though.
perhaps they implement somwthing on their cloud only for paid versions? free version's cloud probably lacks something
According to them it's the same cloud scanning for both free and paid versions.
I don't know if they have a license for metascan 8, 12, 16 or 20 engines to improve the detection rate on the cloud like zemana does
As far as I'm aware it's just their own technology powering their cloud analysis. Never seen or heard any mentions of multiple engines.
Regardless, even if it does have all this technology built in it doesn't really matter if Avira doesn't do a good job at protecting its consumers. It's signatures are obviously good and its cloud scanning is decent but the fact that its mechanistic protections are almost non-existent stops me from recommending it.
