WINDOWS LOCK after viewing online streaming site(s)

Hi

I have a PC running Vista Business (32bit). All my Power Options are
switched off, and I have no screensaver set.

However, if I watch a video on youtube, BBC iplayer, or any website that
streams video, every 60 seconds the PC will lock.

When I say lock I mean the Windows Lock utility that can be accessed by
pressing the WINDOWS KEY + L. But in my case, I am not using this key
combination.

If I dont visit a streaming website then the PC will happily stay 'open' for
me all day, but once I visit just one website.............every 60 seconds
the PC locks itself.

Can anyone please direct me where to look in order to stop this?

I am only noticing this on a Vista PC which is why I have added it to this
Forum. An XP that I have used to view youtube videos works fine afterwards.

I look forward to the replies on this one as its been bugging me for weeks
now(!)

Thank you

Do you have checked virus or Trojan horse ？
