AVG and Avast were made for each other. Avast was trying to develop behaviour-based protection, which was... don't wanna bash, mediocre...at it's best.
AVG already had that. Avast didn't have the LinkScanner (back then), so AVG provided.
AVG didn't have effective definitions, which Avast had.
So the combo created a strong product.
I am unaware as to what Norton can take from Avira, but off the top of my head I see the following possibilities:
- Intelligence will be shared between the 2 companies about every newly-discovered threats. This will most probably start immediately after acquisition.
- Certain heuristics, as well as definitions will be exchanged between the two products. This will probably take few months after the acquisition.
- Avira has a cloud-detonation system, which will most likely be improved and then utilised by Norton. This will probably take few months as well, most likely will be finished H2 2021.
- Norton is currently offering a tune-up app, licensed by a third party. This will be most likely discontinued and the Avira Tune-UP will be offered instead.
- I am unsure to what will happen with the VPNs. Most likely Phantom VPN will replace the current Norton VPN.
These are my guesses over what will happen with the 2 products. Most likely Avira will use the Norton UI, just rebranded. We'll se next year.
