I have a notebook with specific software to my needs, updated avast to the latest version, restart the computer and after that unistalling software to pass the computer to another person.
I find if allways start explorer from the taskbar icon, always crash and restart the entire explorer process( the taskbar is refreshed).
To rapid revolved the problem i choose to reinstall Windows 8.1 from the begining(format and reinstall only the essencial software), then i get another problem, avast always failed to load the ui
From the web i try the recomended choices to resolved, verify avast services are running in automatic, enable remote desktop, reinstall; in the order suggested of priotity
In the main computer, i was getting another problem wich i do not associated to avast but perhaps related, ussually the first start the computer i was getting avast not loaded(red x), upon restart got responsive anb loaded
The only choice remained was unistall avast and install another antivirus, the best of the problemwas ocurring in the lasth 2 month of my subscriptions( to no renovated)
