I purchased the anti virus last year installed it and it worked fine until a couple of days ago it just stopped working. so today several times I downloaded the avg 2015 and installed it. i have an icon on my desktop. when avg opened one time i selected the repair option and it ran fine. i clicked finish. when i go to the avg icon on my desktop and right click and run as administrator nothing happens. when i click open nothing happens.
i have a license.

this is frustrating.
