Just to answer your question properly, I don't think you need to reinstall your PC to get rid of it. Most games are now removing it through an update.

There's a thread on Reddit that collates which games are still using Red Shell and which have removed it: https://www.reddit.com/r/Steam/comments/8pud8b/psa_red_shell...

I think you can just uninstall the ones that aren't planning to remove it yet.

Also, you can opt-out from RedShell's website. Although it doesn't seem straight forward to me: https://redshell.io/optout

It would be nice if malware and antivirus scanners could find/remove it too. I'm kind of miffed that the antivirus software I pay for let this stuff remain on my Windows partition for months even after the software was known to exist.

Removing it will probably break the game (it's a DLL loaded by the game executable, and I'm guessing most game devs don't bother to correctly handle its absence).

People were suggesting the home remedy of adding redshell sites that the software reports to to your hosts list.
