Hello, Aliaksandr.
This is new to us. Could you provide a screenshot (http://avgclick.me/getscreenshot) of the PDF document's icon that you are opening?
Since installed, AVG Secure Browser has become my standard PDF viewer, too (i.e. it opens a PDF file when double-clicked), though my usual viewer (PDF xChange Viewer free edition) is still marked as standard in Open With - Select a program window from the drop menu, as well as in Windows standard program manager. How can I deactivate this feature and start my usual viewer by double-clicking a PDF file?
We are glad to hear that the issue is resolved.
Yes, it might just required a reboot to load the software.
I appreciate your time and co-operation.
