infected files

My avast just found two infected files:
C:\ProgramData\Microsoft.…\mpcache-376274EF804D3609509B0F94E18CC52D63211E0D.bin.VF and
C:\Users\Anja\AppData\Local\Google\Chrome\User Data\Default\Preferences~RF1d5a40.TMP

As it is not possible to repair them, does anybody know whether they may be destroyed withoung harming my system?

I am really not sure >:(
Thanky :smiley:

Is there really nobody who may tell me whether can delete the files? It would help me a lot!! :-X

Are these files detected as Win32:Flufferminer-D?

If so restore them: http://www.avast.com/en-eu/faq.php?article=AVKB21#artTitle
