Your software is too much obtrusive. It try to connect to download.XXX.avast.com where XXX is a changing number.
I understand that your software try to connect to your servers in order to be up to date. But it tries to do that every 15 s. It’s unbearable.
I am using the home version of avast (the last one)
It doesn’t do so on mine, avast checks for updates when a connection is first established and then every 4 hours if you remain connected.
What this sounds like to me is the update is being blocked and if avast can’t connect to one of the download servers it cycles through the ones in the servers.def file.
What is your firewall ?
Does it allow avast.setup internet access ?
- If it does delete the entry for it and do a manual update and reconnect to the internet, this will force the firewall to ask permission again.
avast checks if there is an available connection each 40 seconds (not 15).
If there isn’t, wait more 40 seconds to check. Checking does not take more than one second and, of course, does not use the Internet band.
If there is a connection, check for an update. If there is not any new file to download, wait 4 hours to start checking again. If there is an available update, start it and install it. Again, wait 4 hours to check the next time.
Some of this settings could be configurated different, I posted the default values of the avast4.ini file.
The updates are incremental.
Anyway, you can set the update to manual if you want that avast stop check for updates.
