Hello Apostolos Dimopoulos
Thanks for getting back to us.
The new dump file is pointing to the cause of a driver left memory allocated, which can destabilize the system. This also point out that the faulting driver is aswNetHub.sys, which is also a driver from Avast.
May I know if this happen after you reinstall Avast?
Please let me know so we can work on this together.
