I think I downloaded a malicious extension to my MacBook Pro

well it finally happened, I fell for a pop up that looked just like a “[insert website] wants to send you notifications - block or allow” pop up you’d see on Google chrome. It opened into a website that then seemed like Google chrome was suggesting an extension program that would block unwanted ads. I installed it and then realized ~wait this isn’t on a valid google website~ and automatically removed the extension, deleted it etc. I ran a virus scan that told me that website was malicious. It would’ve told me the extension was malicious too but I no longer had it installed. Nothing weird has happened… I did a full scan of my mac and it found no malware in my computer, and I’m updating to the most current mac software after reading its ability to scan & remove malware. What do you guys think, is everything okay? Should I do anything else? Thanks for your help.
