Packed Generic 200

I have detected this virus thru Norton Internet Security.  I have tryed to remove it using Spybot, SuperAntispyware and Malwarebytes, but the system will no allow these programs to open.   and I keep getting a popup, that looks like a windows firewall alert, but I think it is a adware program.   Occasionally there will be three porn related links that appear on the desktop. 

 

It killed my internet connection, but I finally got it back and working.

 

one of the files is backdoor.win.kbot.al

 

there are several others, but this is the only one I wrote down.

 

Any help?
