Hello, thank you for reaching out to Microsoft Q&A.
WSHelper is included in almost any software developed by Wondershare, the most popular one is Filmora.
Go to Settings > Apps > Installed Apps > look for Wondershare software like Wondershare Studio or Filmora (If installed) and click Uninstall. See if you're experiencing the issue.
If not, open the Task Manager, select the Startup tab, and disable the app from running at startup to prevent it from launching automatically when you turn on your computer.
