How do I remove malware I accidentally imported into PowerShell?

Running that line of code sounds risky, and you're right to be concerned! It's crucial not to run any commands that you aren't sure about. If you've visited the site mentioned, it might have downloaded some malware. The best option at this point is to wipe your system clean. I recommend doing a fresh install of your operating system after backing up your important files. Make sure to use a USB flash drive to reinstall, and avoid using the reset option in settings.

Yeah, it's pretty much game over. Wipe the whole system clean and install a fresh copy of Windows. Just make sure to back things up first, but be careful not to save any potentially infected files.

If you're worried you may have malware, don't try to run that command again! I've read that it calls a web request to download something malicious. I'd strongly suggest reimaging Windows or, at the very least, running a trusted antivirus program to scan your system.

I wouldn't even risk running any more commands. Just to give you a heads up, the script is designed to be sneaky and bypass detection. My suggestion is to format your hard drive and start from scratch; that's really the only sure way to clear everything out.

The clean install is your best bet. Just make sure to disconnect from the internet before you start the process. Once you're set up again, change all your passwords too, especially for banking and personal accounts. Always better to be safe!
