Yes. It's been discussed on the wilderssecurity news groups. The general
consensus from users is favorable. I have not tried it, so what I am

I just installed it and it is running along with the new Grisoft AVG_7_Free_
Beta. Both seem to be running soothly. The Prevx is using 0 resources
and by appearanes it seem to be doing it's "thing".
