Ooops, the affected file is aswsnx.sys, not aswsp.sys. I have modified previous post.
Btw, i not always get BSOD. After connection, when system is going to crash, the pointer get very slow fore several seconds, and then i get the BSOD or the pointer freeze and i have to force power down. As i said before, nothing of this was happening before upgrade.

Is there any way to revert to previous versión?

Thanks
