Can anyone tell mewhy I have to see a window when I start up from avast asking if I want it to make any changes to my programmes before I can go online. If I don’t need to see this, how do I stop it from happening ???

I don’t see this, can you attach a screenshot of the notice.

What avast version are you using free/pro/AIS/Premier ?

Avast 9.0.2006 is the newest.

Just released a few minutes ago.
