MScript.exe , usb shortcut virus ?!

Hi everyone,
I have this shortcut problem. I think it came from my flash drive. All the files on the flash are shortcuts, 4 shortcuts folders are there but they are not from me and they remain there even after a format. Also one of the shortcut folders appears in every general folder of my HDD. And all the shortcuts lead to this MScript.exe in my system32 folder and i cannot delete it…
Please help :innocent::innocent::innocent:
