Thank you.

I have reinstalled the AVG Internet Security 2015. After the Installation AVG Internet Security 2015 my OnlineBanking+ Program of Buhl GmbH (Germany) hangs-up after the password has been enterd. By deactivating AVG Internet Security 2015 the software starts without any problems. I have deinstalled the software OnlineBanking+ Program and reinstalled it. But the same thing happens at the login the program hangs-up and can only be terminated by the Windows-Task-Manager. The Implementation of using the Exception of Files or Folder does not help. My OnlineBanking+ still hangs up during login phase
A similar situation has occurred with the Belkin USB Network Hub. After I had defined the Belkin USB Network Hub in the Defined Network Section of the Fire Wall of the AVG Internet Security 2015 and added it to the Whitelist for IP-Adresses. The Belkin Hub identifies the USB Stick which I have inserted in to the hub. By pressing the button 'Connect' the hub displays the message box 'connecting' but no connection occurrs.What is the matter mit AVG Internet Security 2015?!!! All these Problems didn't occurr with AVG Internet Security 2014.
How do you propose to solve this problem?!
