I have had a couple of recent popups regarding ‘Avast has detected privacy issues’.
There are several items listed, including:
My location is exposed.
My IP is exposed.
MY ISP may be tracking me.
It would be great to know if it was true. However Avast cannot even tell that I am already using a professional VPN service. So the items it claims are at risk belong to my VPN service, not my PC or my ISP.
Get a grip, Avast! This would be funny, if it wasn’t so sad … 
That’s an ad, you can remove SecureLine.

No SecureLine installed here. Only File, Behavior, and Web shields are active.
If that is an ad, it is cleverly disguised as an actual detection. It is declarative of false status and detections, so it is treading precariously close to ‘scareware’ tactics. Not a class act!
Post a screenshot.
I would if I had one, but I was taken by surprise and didn’t do a screen grab before closing the window. Will do if I see it again!
So far it has occurred once on each of the two machines I have running the latest version of Avast.
The reason that I know it was not a static ad is that it contained the actual IP address I was connected to, and the city of the virtual VPN location I was currently connected with (3rd party VPN).
The only way it could do that was to run a script to see what my current IP was, then do a lookup for that IP location. That’s a bit more than a static ad is capable of, don’t ya think?
