Grrr, surely this has to be anti-competative?
Symantec owns Norton
Avast owns AVG
So that is 2 AV vendors gobbled in one go.
Broadcom own NortonLifeLock who in turn own Avira. This is mistakenly thought to be the same as Symantec Norton.
Intel own McAfee.
If you dig back on many of the smaller vendors you find they end up in the same place with one parent company.
