Can you say your suggestion more clearly?

What exact part of disabling the optional autorun / autostartup items was not clear? I mean, the explanation could be a whole article by itself, depending on the level of the target reader.

That was part of the suggested test after reboot, and after 10 and 20 and 30 minutes; all of those with the optional startup items being disabled, leaving enabled only the essential ones.

The other suggestion was about a clean install of avast. That means REALLY cleaning up ALL previous installations and updates of avast, and only then installing anew the latest stable version. Are the steps of this suggestion not clear?
