A persistent, reproductive trojan

Hi,

Every time I plug in my USB flash drive onto my desktop machine, AVAST (home edition) will find the file called autorun.inf contains trojan. I deleted that file but just 3 seconds later, that file come back again which still contains trojan ( AVAST will pick up ).

It seems some process in my desktop system contains some hidden process which will produce autorun.inf file to removable disk persistently. AVAST (home) seems not find that process.

I am asking for help that is there any solution from AVAST can detect which process is persistently producing such viruses (producing specific file to specific location) and which file will create such a process then I can delete that real virus source.

Thanks
