naelmedhatyou're in the wrong place.

This forum is for the Microsoft Forms application.

What you see there is a malicious piece of software that is likely running as a service on your computer.

Svchost (that's actually contraction of 'servicehost') is the operating system component that's responsible for hosting (running and protecting) system services, that's why you see that one. Rundll is another system component of similar nature - that means whatever you're fighting has taken root and is actively using multiple metods to ensure you DON'T root it out.

The simple/cheap/fast route advice? Rely on your backup (or on your cloud copies of files) and get your PC wiped completely - reset it to factory settings by formatting the hard drive/reloading from image. In many cases, that's gonna be faster than trying to sort out what malware you picked up and how to remove it.

And then, have a think what potentially unsavory site you were on recently, and don't go there ever again.
