Help with these viruses!!!!

Hey! Hope you can help me. First of all, dumb question..... is Symantech antivirus the same as Norton antivirus??

Anyway, I have these viruses winsystem.exe, cmgrs.exe, tsv2.exe, iemultjx.exe  but the updated Symantech Antivirus can't do a thing. I even manually quaratined some of them and still doesn't recognize them as Infected.

 

What can I do?
