You have to stay above all this( I hope it is the right english phrase). Your startuplist shows that you do not start much or useless Software, one thing you could try is to temporary disable you firewall to see if it disturbs with Avast. If not, you should use an other Scanner for your on access protection and use Avast only for on demand.
It is not easy to say what happens on your system, but if you can make Avast responsible for your problem, change your on-accessprotection, wait for a new release. Thats it!
