Frequent Antivirus warning on System Files

[hakah]

I have closed my System Restore and have the whole system scanned by my Antivir Premium and MBAM respectively. There were files detected by both and were totally removed thereafter. But there is still one file left behind in MBAM quarantine area which cannot be removed.
The File is found in C:\Documents & Settings\funshion\historytorrent\十三刺客.mp4.fsp and is detected as Adware Funshion.
(that file is Chinese movie which I remembered have been deleted recently)
There is no way I can remove this file and hope Forum member can give a hand on it. Thanks for the kind assistance!
