Funny that Avast Free says one of my vulnerability's is my webcam and there is no webcam attached to this computer, nor built into the monitor.
Interesting, was this after running a Smart or other Avast scan ?
I tend not to run on-demand scans, especially the Smart (not so) scan as i find this is more a vehicle to promote other avast products.
So even though I have a camera embedded in this laptop Covered with a very expensive solution, a piece of a sticky PostIt note
I have never had one of these notifications.
