I restarted it and so far it seems to be ok. I'll run a scan. Thanks.
What you saw was an advertisment. Not a genuine warning at all but a SCAM.. YOu call the number and they help you install a nasty bit of software and then charge you an arm and leg to remove it.
YOu did the right thing by NOT calling them.. The Ad has some code that basically locks up the computer so a RE-BOOT or in some cases the old 30finger bit (Ctrl-Shift-Escape) and kill the browser works.
But it is usually easier to force power off (Sit on the power button) and then re-start.
IT IS A SCAM. Micerosoft will not scan or monitor your computer (At this time)( unless you ask them to. and I'm not sure they can even then... In the near future this may change as Im told MS is changing their marketing.. but that is rumor).
