is z-library safe? Am i infected after running pdf from there?

Specificially https://en.z-lib.gs/

I downloaded some pdfs from there and according to virustotal and some pdf online scanner i tried, they have something possibly malicious going on in them. I already deleted them but i opened them in firefox pdf reader. I dont have acrobat installed.

Scanning my system with malwarebytes now, but nothing is finding anything wrong and I havent seen any suspicious activity.

Here is the analysis itself.

I'm starting to panic, please help if you have any advice

Thank you all, you are wonderful people
