Hi. A few days ago, on powering-up IE8 and clicking on Identity Safe, I had a warning message that Identity Safe wasn't switched on & that I was at risk.

I went to setting and it was shown as switched on. I rebooted and it was back on.

But now, I'm having problems referred to in KB894278 - http://support.microsoft.com/kb/894278:

I get the "Serious error has occurred" and also my PS automatically restarted.

I followed the instructions in that KB article but there is no trace of the spyware referred to.

(1) What caused Identity Safe to be switched off eg could it have been a trojan that NIS failed to stop?

(2) Could my KB894278 issue have been caused during this "at risk" period.

(3) Should I start another thread re the issue? and finally

(4) I received an email from NVIDIA a few days ago saying their website had been compromised and that they recommended I change all of my passwords. This is a hell of a big job and I'm doing it bit by bit. Could this be the cause of my current problems?

SOS!!!

Thanks
