Thanks for reply Jx,
Yes you’re right, I’ve install the BP managed version, over the Avast PRO 6.0.1203.
The problem will be fix with the other relase, or I must do a clean install?

I’ve another problem:
I use on two PC Skype with Philips Voip 321.
With this relase Philips Voip 321 driver can’t communicate with Skype.
With Avast PRO 6.0.1203 I haven’t no problem.
Is the problem solvable?

Thank’s a lot

edit
with a clean install the first problem is solved
