NAV not blocking b.exe which appears in task manager

Hi

 

I am having exactly the same problem as others on the board. There is a "b.exe" that shows up on my task manager and broadcasts radio/ads on my speaker. Dont know what else it does, but looks like it sent some messages to all contacts from my Yahoo messenger. Norton AV - with updated definition and running full system scan - doesnt seem to be removing or blocking this.

 

There seems to be a a.exe, b.exe and c.exe and a.dat in my user-AppData-Local-Temp folder. I have deleted these but they seem to keep returning after restarting the computer. 

 

Can someone please help? I am on Visa Home Premium and NAV 16.5.0.134

 

Regards
