It sounds as if you've picked up some malware/adware. Run a utility such as Malwarebytes or Spybot Destroyer. (Free Programs)
Also look for entries in your Add/remove programs that you don't recognize. Remove foobar, Gamevance, Yontoo, Shop at Home & Browse 2 Save if you show them listed.

Also, if you don't recognize a certain listing such as ShopAtHome in your Add/remove programs,
just Google it to find out information. When you've determined it's unwanted, remove it & reboot.
Some malware sweepers may not catch them. They will often come bundled with programs you choose
to download - always opt for a custom download when given that choice! - & could also be added
in program updates such as browsers, existing toolbars, and other auxiliary programs - always choose
to set these programs to "prompt me when updates are available!" rather than automatic updates.
These do not come from Pogo.com.
If you've recently downloaded a program, you could start there. Good luck!
