A few changes to the file shield that I did is exclude read/writes for image/video/text files because if im using them as image/video/text files there should be no risk
You are wrong. image and video files can also spread malware.
The only other excludes are my steamapps folders (no need to scan huge gigabyte files) and some trusted programs, especially ones that I never update even, so their safe in their frozen states.
Wrong again. Those can get infected too.
I have malwarebytes and avira and others
Wrong again. Never have 2 (or more) av's at the same time at a system. Malwarebytes and avast = ok.
And really the only things avast ever picks up is false positive keygens or cracks
So, you are using illegal software. That makes you a thief.
I've used computers for more than a decade I know how to not get infections
No you don't know how to prevent infections. Wow, more than a decade... I only since 1983 when I build my first computer with transistors, resistors and other electric components.

You disable things that help prevent infections and you claim you know how to prevent infections?
You are using illegal software and such and you claim how to prevent infections?

You don’t know anything at all when it comes to prevention.
