I can only see wallpaper!

Hello, some days ago I got a virus, and 2 anti virusses I didn't know I had popped up in my start menu, and it was total chaos. Every time I tried something to stop it, a bar popped up saying "Panda.exe is infected" or something like that, so I shut down the computer and now when I open again all I see is the wallpaper, and NO I cannot open explorer.exe, sfc /scannow does not work, and I CAN'T find where the system recovery tool is.
Any help will be gladly appreciated.

Some more info :
It seems that although the majority of my files are missing I seem to be able to run E-mail and Internet Explorer, although IE cannot visit any sites, it just comes up with a message that it cannot open the site.
Ironically, my E-mail can both send and retrieve messages.

I can also run diffrent games and programs with no lagg or problems at all.

I would love to see answers.
Thanks!
