What it detects

This rule detects the NetSupport client binary client32.exe executing from an AppData directory, the location where the ClickFix campaign deployed NetSupport as a RAT. Although NetSupport is legitimate remote-control software, execution from a user profile directory indicates abuse for unauthorized remote access.
