jjysp.dll

The jjysp.dll file is associated with a persistent RunDLL error that appears at startup on Windows systems. Users report a message stating "There was a problem starting jjysp.dll" and find the file referenced in the registry under HKLM\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Run with an unknown manufacturer. The startup item is listed as "sta" and runs rundll32 with jjysp.dll. Since the file is not widely documented online, it is often suspected to be unwanted or potentially malicious. Disabling the startup entry in System Configuration is a common first step, but users may need to scan for malware or manually remove the registry entry to fully resolve the error.
