Does AVG Protection block third party access to computers they protect?  This is a new computer and has never had any third party legitimately access my computer but it appears that someone has accessed it and from time to time, scrolls without my touching a thing.  It happens when connected to the internet.  I have run several AVG whole computer checks but found nothing.
