Good morning everyone. I joined this forum today and I would try to give my little contribution.
I use Avast free and Malwarebytes Anti-Malware 1.75 free (installed by a few days) with all its functions PRO active for a few days. Unfortunately, since I updated Avast free from version 6 to version 7, my PC slows down a lot, and sometimes it seems stuck, especially when I start the database update MBAM.
If I disable the function "Block Websites" of MBAM, the PC back fast.
So I remembered that a long time ago I solved a similar problem by disabling the protection function "JS Javascripts" Avast in "file system protection". So yesterday I did the same thing, and the problem is solved. Unfortunately, doing it this way, the protection of Avast is less powerful, so I hope someone more experienced than me can find the correct solution.
I apologize for my English translated with Google
