Programs not responding.

[Stynche]

Hello!
So, I've encountered this problem few weeks ago and was searching for a solution since then with the mighty google, but, as you see, with no luck.
What happends:
I make any sort of program, none of the programs work. Console window pops up, but nothing gets written whatsoever. on top of that, 3 processes in task manager always come up and I cannot close them, even with external programs, I have to restart my computer in order to close them.
Here's a simple example of small code I put up just to show what I mean:
written and pressed "build & run":

after few moments:

after I closed it, made some edits and tried to compile it again:

Windows 7 x64 Home premium SP1;
Codeblocks version: 13.12
If there is a solution posted somewhere, I am truly sorry for wasting your time.
If anyone could help me, I would be thankful. Sorry for my english in advance.

Do you use an antivirus-software (probably avast) ?
If yes try what happens if it is disabled or your programming folder is whitelisted.

It worked! I am both happy and feel as an idiot, but, anyways, thanks! After disabling avast i can now manage to end processes and successfuly run code. Thank you a lot, it looks like I need to tweak antivirus a bit.
