Where is this Nodejs.exe located?
Do you have the path in the registry?
Or did you search on the disk?

This scheduled task seems a bit suspicious:

What is in this folder C:\Users\ffame\AppData\Roaming\Boken\?

In the "Run" field, type notepad and hit OK.
Copy/Paste the following into it:

Reboot:

Once the text is pasted into Notepad,
Menu "File" then "Save As",

On the left, go to the Desktop,

In the bottom field, enter the file name: fixlist.txt
Click on "Save", this will create fixlist.txt on the Desktop.
