Eset NOD 32 MBR cleaning problem

I'm using Eset Nod 32 antivirus, Windows 8.1 64 bit. Today I found w32.Sality virus from an USB drive, it looked like the virus affected the MBR (Master boot record). I tried all the antivirus softwares and they detected the virus, but they are can't clean it. I must repair the drive MBR by myself. Is there a good Antivirus program that can prevent/clean the MBR virus from Windows? Is there any GUI tool for repairing MBR for USB?
