One thing I’d like to know is why Avast needs to be updated so often. I don’t mean regular updates to its virus database, but a new version apparently. I had just restarted my laptop after doing a Windows update, and then Avast indicated it needed updating. So I clicked on it to make that happen, and it took about a half hour to download 3 parts of the newest version. While this was happening, my computer ran very, very slow which kept me from doing anything else. After it was done downloading, it said I had to restart the computer again.

Is there a set amount of time that goes by before a new “version” comes out? Is it even necessary to upgrade to a new version, or do updates come out automatically for the older ones too?
