There are two types of updates:

  1. Virus definitions (VPS): normal updates (2-4 times a day generally) and streaming updates (microautoupdates): http://blog.avast.com/2013/09/16/seeking-perfection/
  2. Program updates: major version (once a year) and minor ones (each two months generally).

Do you really think it’s too much?
On protection, everything resides on updates :slight_smile:
