W7 SP1 update: black screen and "circle" cursor


W7 update tool just installed SP1 and now when I login with my admin user I see only a balck screen and the "circle" cursor ...

If I login with my backup admin user all seem to work but clearly I miss my iTunes and others ...

Somewhere on the net, I found that this behaviour could be related to ZoneAlarm and they suggest to uninstall it ...

Any experiences here?

I've W7 Home Edition (with Italian Language Pack) on a Toshiba Satellite A500-1EK with i5 and 4GB of RAM.

Thanks in advance,

I've upgraded Zonealarm from 9.1.xxx to 9.2.xxx and now all works fine again ...

My best,
