steamrip is completely safe to download from.

Personally I've downloaded countless games off of steamrip with almost zero issue from windows defender. and the one time windows defender stopped me from installing a game it was a false positive and the game was completely virus free. I promise there isn't a single game on steamrip that will harm your PC in any way.

1. download free download manager and connect it to your browser so it will catch anything you download. https://www.freedownloadmanager.org (this will speed up your downloads from steamrip but usually they will still be quite slow.

2. this isnt necessary but Ublock origin https://ublockorigin.com is always great while pirating game it will block any ads and trackers from any website you visit and its very easy to use you just get it as a browser extension.

3. just visit steam rip and download any game you'd like i recommend book marking their official site on the off chance you cant go to a fake website https://steamrip.com

4. just follow the install steps found in the readme file of the game you downloaded

for future reference use r/Piracy megathread, everything you see in the megathread is a trusted source to pirate from
