Threat Secured pops up every other minute

Hello there, I keep getting this "Threat Secured" pop up every other minute. Even after I "SCAN MY PC" and it says my PC is secured, it still pops up. I do not know what to do and it is annoying. 

The details is as followed:
 
Threat Secured
We've safely aborted connection on 198.144.189.68 because it was infected with URL:Blacklist

Threat name : URL:Blacklist
URL : http://198.144.189.68/fakeurl.htm
Process : C:\Users\Desmond Low\AppData\Roaming\WinSupport\client32.exe
Detected by : Web Shield
Status : Connection aborted

It is getting somewhat annoying and I can't get rid of it.

Please help.

Thanks,
Desmond.
