but this solution seems not to be working!!

Its that obvious. Thanks, I didn’t have to do the reinstallation of the program with extra junks I don’t need. Also, earlier avast didn’t have such problem with the same setup configuration during installation as with the present one. So, it may be due to some coding issue and I hope they look into it further, assuming other users are affected the same way (which needs confirmation as only 3 of us had actively confirmed with another 15 votes).
