I didn’t go any further with your Hijack this log other than to note you have NAV and Avast running.
They will conflict with each other and cause problems.
If you search this forum you will find many posts about NAV and how to completely remove it.
Perhaps a boot-time scan with Avast afterwards and another Hijack this log file might help us to help you better.

Forgot to welcome you here, very remiss of me :o
