I notice you have the shortcut keys enabled - I wonder if that may be part of it… I use that tool on a daily basis and have had no problems with it… My set up is the safe as yours AIS win 7 64bit

Same thing here, Avast! IS 5.0.667 on a Win7 x64 machine, no problems with the tools.
Even similar hardware:
Phenom II 955BE
4GB DDR3 Ram
Win 7 Ult. x64

Any other security software you may be using?

thank you !
it’s possible than the shortcuts are in cause, I want to try disable its. I do not remember having setuped its myself.
I have searched for a setup function in Avast to disable the shortcut keys but nothing found. Perhaps some windows functions ? You know what can disable shortcut keys in Avast ?
Thank you so much !

To disable the shortcuts, Open Avast! GUI, press Alt key, done.
