how to remove hao123syspop_weather.exe

Although Norton has 'Blocked' a threat called

Filename: hao123syspop_weather.exe
Threat name: Trojan.GenFull Path: c:\programdata\toolsupdateplatform\download\hao123_sys_weather_0728\hao123syspop_weather.exe

It pops up again repeatedly slowing up my machine considerably.  I have located the file and tried to delete it - to the Recycle Bin - but as soon as it is removed, it reappears.

How do I permanently remove this threat please? 

Thanks you
