I Think I’ve Been Phished—What Should I Do Next?

Unfortunately, the command you ran is very dangerous. It downloads a script from the internet and executes it right away. It's likely that you've installed malware. The best course of action is to back up your important files and completely reinstall Windows to ensure your system is clean. After that, you'll need to change all your passwords, especially for any accounts you accessed on that machine.

You should definitely consider your laptop compromised. Reinstalling Windows is the safest option to wipe out any potential threats. After that, create a new admin account for setup but use a non-admin account for daily tasks. Just make sure to reset all passwords for any site or service you accessed from your device.

After running that command, assume your system is fully compromised. It's crucial to reset Windows and go through all your accounts to change passwords. The 'admin' account is for initial setup and troubleshooting, while the non-admin account is for everyday use to limit risks.

So, that command basically downloads content from a specified URL and runs it as if it were a script. It's a common tactic used in phishing attacks. Since you've executed it, assume that your machine is compromised. The recommended fix is to do a full factory reset or a reinstall of Windows to eliminate any malicious files.
