Yes, sure all my drivers, softwares and OS are updated... That is second computer (not the same computer) where this error occured... The only solution is to desinstall avast... The other computers with the previous version of avast are working fine but the latest version brings up the 0xc0000005 error... unfortunately :-(
Here is the issue
https://www.avast.com/faq.php?article=AVKB268How can I resolve Behavior Shield issues?
Behavior Shield monitors the programs installed on your PC for suspicious behavior that may indicate the presence of malicious code. If this component blocks a program that you believe is safe, ensure that the latest version of the program is installed on your PC. Behavior Shield may treat outdated software as a potential security threat.
In some cases, Behavior Shield may display the error message The application was unable to start correctly (0xC00000e5) or stop an application from running and freeze your PC.
We are investigating these issues and working on a permanent solution. If necessary, temporarily disable Behavior Shield in Settings ▸ Components.
We strongly discourage permanently disabling Behavior Shield. When enabled, this protection component provides vital security for your PC.
