Smart defrag message on boot

My laptop uses Win Vista 32 bit. Every time it boots, I get the Iobit message: Iobit Smart Defrag v 2.0 is available. I have uninstalled all Iobit software (Malware Fighter, Uninstaller and Apps Toolbar). The message still appeared so I deleted the Iobit program folder (which the Uninstaller apparently missed). Auto Runs showed the Smart Boot Time.exe was active was active so I deactivated it. But the message still appears a boot. Any suggestions on what could be causing this?

 

Download and run Microsoft's Autoruns and use its Search function. You will soon find it and be able to disable it.
