I have absolutely no idea, I just know the people in this thread and the other one who've indicated they have a problem, and a good buddy of mine in kentucky's having a problem.
so I can conclude, based off their reports, and your indicating to the contrary, that theres a false positive in the system for some reason or EVERYONE who uses both avast and amazon would be blowing a fuse.
just cause person a is having a problem doesnt mean person b will.
