Hi all,

My netbook has started to turn itself off. It does so correctly, as if 
I'd hit alt+f4 from the desktop, then enter on Shut Down. the problem is 
that it shuts off when I'm in the middle of doing something, and I don't 
always have time to hit the Escape key or tab to and enter on Cancel. 
I've already checked my power manager, and it seems okay. Now I'm trying 
to run a virus scan and am unable to do so.

So my questions are these:

What may be going on?

How can I scan my computer from the web?

Here's the problem, which started yesterday. I was writing an email when 
the computer shut down for the first time. I thought I must have 
inadvertently hit one of those magical key combinations that is supposed 
to make Jaws crash. I powered up and wrote a few more emails without any 
problem. Then again, in the middle of an email, it started to shut down, 
only this time I was able to stop it by hitting Escape or Cancel (don't 
remember which). Half an hour or so later, while I was arrowing around a 
work website, the computer tried turning off again, and again, I was 
able to prevent it from powering down.

Over an hour later, I went to the BARD website, started the download for 
three books, and read some more email. After a little while, I closed 
the email program so the computer could just download in peace. I sat at 
my desk another ten minutes doing this and that. Then I left. Fifteen 
minutes later when I returned to check on the downloads, the computer 
was off. When I turned it on again, I noticed the books had been 
partially downloaded.

This morning I decided to get to the bottom of the problem. I checked 
the power manager, which was exactly as it had been before. Then I tried 
running a full virus scan with Microsoft Security Essencials. Both times 
I tried it, the computer shut down about a minute into the scan. I'm not 
sure what to do to get a good virus scan.

Any help would be greatly appreciated. I'm running Windows 7 Ultimate 
and Jaws 13 Professional.

Ciao
