@CraigB: It worked mate. I did a clean installation i.e. uninstalled Avast via add/remove and used the avast uninstall utility. I then had to manually disable windows defender settings from the task manager and from the windows defender security center and after that re-install Avast. I came across few issue/concern. Upon installing Avast it opened up the Avast GUI and it said finishing avast installation 0%-99% (See attachement avastgui.jpg). It seems to get stuck on 99%, but when i closed Avast and re-opened Avast the percentage was gone so i assumed it finished the installation. After that I restarted my laptop manually. After that I opened up the Avast GUI again and went to the subscription tab to enter my email address so I can register it, but I didn't see the register form but this one appeared (see attachment subscription.jpg). In this new version don't we have to type our email address anymore?
