Do I need to reinstall my whole OS after using brave to visit deep web?

Well, I know that brave TOR feature is just for convenience, but I went in hidden wiki and duckduckgo from deep web. I also did open a weird site selling paypal accounts from hidden wiki (I didin’t buy and will not buy anything, I was just curious). But the question is: Is my pc vulnerable now? I purged brave and then did a clean install, but is this sufficient?

If anyone with experience at deep web can help, would help me a lot
