Can't get AVG Internet Security icon to open

Used to be, when I inserted a thumb drive, AVG automatically opened and offered to scan it. Now, AVG does nothing. And I can't figure out how to ask the program to scan it.
Any help will be appreciated!
Thanks

Hi Dan,

We're glad to look into this & help you.
Please let us know the version of AVG installed on your computer (Open AVG - Menu - About). 
Also, clarify whether you're able to scan the USB drive manually through the contextual menu (right click on drive & scan using AVG).
