Think I've got a problem on one of my pc's. First had a msg saying Windows Defender User interface problem, I went into Control Panel / Windows Defender and the pc closed down. I restarted and noticed if I select Security Centre, nothing happens. If I select WIndows Defender again, the pc gets a bluescreen and closes down again.
Nothing on this particular pc - I was relying on Windows. I do have a multi-pc Norton licence, I've downloaded & installed NIS2010 but the initial full scan has been running for a 2-3 hours - is it spinning its wheels?
