@leocg I trust more antivirus than Opera. Opera as a quality product died along with version 12. Now it's garbage full of ads and bugs. And it's requiring dubious permissions to connect to dubious sites.
I have not received an answer why Opera is trying to access this site. Although I found a description in Google that this is related to a web camera. Are they trying to watch me without my knowledge?
As Google writes, I'm far from alone with this problem. It started about 7 months ago.
