Help me figure out if i downloaded something shady, please

Hi everyone, i'd like to start off by saying that i've been pirating for a while and have always stuck to sites that are reccommended on various megathreads and considered safe. Sorry for the long winded explaination.

So i was downloading a game from gamdie (which i have before with no issue) and one from steamrip (i don't remember any issues there) and the gamdie file was almost immediately flagged by WD as trojan. i didn't even make it in time to click anything that all these other trojans started popping up and WD closed on its own. i panicked and deleted the files and tried to run malwarebytes which i thought was installed already (but apparently not) and it turns out i can't even install it, it says the app can't run and to check different versions. I checked on taskmanager and it seems nothing immediately fishy was there, WD gave me back a list of the trojans it found and i deleted them, firefox has acted weird a couple times (duplicating tab instead of opening new one, or opening settings instead), and some of my login info is gone from my browser. i still can't install malwarebytes, and i'm kinda not handling this well, so any help is appreciated.

i couldn't read what all the trojans are and WD won't tell me what they are now, but i remember having seen trojan wacaca (or somehing) and trojan malmar (or something like that). Thank you!

Edit: thank you to everyone that replied, between your advice and the sources I found here (linked below) I apparently found a cryptominer and it seems my system should be clean now. I'll run some extra stuff to be sure and hopefully that will be that. Have a nice day!
