@katyblessings It is a good question because nowadays it is hard to find good antiviruses and it can be only my opinion. But there are some antiviruses that are good and can really protect your PC from infection. As for me, I like the only antivirus software - Norton. I like that it does not overload the system, does not make each minute checks and I like the interface. It is enough for me. Also, I have found such information as Norton security rating 2020 and I'll continue using this antivirus after it.

You can try to follow such steps. I've enabled dark mode in Youtube in a reverse way. Login to your YouTube account using Opera and Click View and select Show Developer Tools.

Try to find some if this code var cookieDate = new Date();

cookieDate.setFullYear(cookieDate.getFullYear( ) + 1);

document.cookie=”VISITOR_INFO1_LIVE=fPQ4jCL6EiE; expires=” + cookie Date.toGMTString( ) + “; path=/”;

I use it to run dark mode on Youtube. I've just added this code to the Console.
