I am currently using an HP Pavilion laptop... Windows 10... with ESET Smart Security, 2016 Edition. At some point, with the notifications that pop up to ALLOW or BLOCK a process or application, I evidently was too cautious and inadvertently blocked my Webcam. I checked my Camera settings and all the apps appeared ON. I know what I know... and in knowing that, I also know what I don't know. I don't want to mess with this issue too much and make it worse. I would think that it shouldn't be TOO hard but, as I just mentioned... I know what I don't know. Would love to hear some encouraging words of a relatively easy remedy. Thanks!
