Windows media center

I would send a screenshot if I could.  I can't get screenshot to vcome up on my computer. The only thing I can get is the 'WINDOWS MEDIA PLAYER' screen.  I understand there is a virus that that name.  You think that's what I have?  Why didn't AVG stop it?

This program has my pc locked up(well....almost. I can get to my emails, but that's about all).  I am using Windows 7 Home Prem.  When I try to access AVG the 'windows media center' pops up.  Can anyone help?

 Every time I try to go to clipboard or paint to get the screenshot it just comes up as Windows Media Center.  I'm stuck.
