Fake Captcha Win + R

So I found a gym in the local area, clicked on their website through google maps, fake gym, fake captcha that I saw coming obviously. It asked me to do Win + R -> Ctrl V -> Enter, which I knew was suspicious but my keyboard shortcuts are too autonomous to stop myself that I followed through with it.

I managed to shut my pc off hoping to cancel the installation of whatever it did, but I know it’s not usually effective. The most obvious clue is that websites that I was previously logged into before the restart were now asking me to log in, when for the previous week they’ve remained logged in. Running a comprehensive scan now but…

Question is: will it be enough or do I still need a clean reinstall?
