Windows 10 not closing down properly

I use several AVG products. I am experiencing major problems working with my computer. Programs are not loading (timed out). When I shut down in order to reboot, an error message reports that a private security program is preventing the computer from closing down. Is this a bug in AVG?

@James: The problem is last Antitrack update. Lots and lots of users are having the same problem. Same for me.

Just:
- Uncheck "run antitrack at windows startup" on the antitrack options (for not having to do the next 2 steps each time you turn on your computer)
- Close antitrack from the system tray
- Kill "avgantitrackfilter.exe" proccess in the task manager
DONE. You will have your internet connection working perfectly again.
And the MOST IMPORTANT step: DEMAND AVG FOR REFUND, as they sold you a completely crappy software. Maybe this way they think twice before releasing a crappy update, with a HUGE BUG in it.
