Win32:Tibs-AGC (Wrm)

The above subject infection was found when I scanned my computer with Avast. however when i try to “delete” it or “repair” it or move it to the “Chest” the note under operation says “Error occurred moving the file to chest” or Error occurred trying to delete file" etc.
What do I do?? Is the COMPUTER STILL INFECTED??
