I got it !!
Sorry for blaming VTD, Nod32 was indeed the sw that caused it.
A google on the name on the tempfiles was pointing me in the right direction.

Whats needs to be done is to tell Nod32 IMON part to exclude VTD Agent and VTD Video and hey presto no tempfiles.
Sorry again for beeing quite stubborn and making you spend time on this.
Now I just need to see if VTD is up to the task in watching over my boat, waves can be a bugger...and tripping motion sensors.
