Windows Performance Adviser

Anyone come across this "Windows Performance Adviser" (window name is "Protector-wvdk" or variant)?

 

I've searched this forum but nothing comes up.  Googling also didn't have any Norton/Symantec related page.

 

As this came up on another non-Symantec protected computer (which have Avira Free installed), I am not sure as to whether NBRT will help (NBRT is still downloading def update in a very slow speed).

 

According to the posted date on http://www.bleepingcomputer.com/virus-removal/remove-windows-performance-advisor it seems to be a recent-new threat, and the date corresponds to the date this particular computer is infected with.

 

Any advise/update from Symantec on this threat?
