i scanned my usb device, then i got this result:
error: file is offline - it is currently not available (42006)
i can’t seem to do anything with it.
if you disconnect USB … and connect again … same error?
USB experts are notified…
Hi,
avast say:
E:\autorun.inf <— I can’t find it.
You have been probably disconnected the USB memory device while avast has preform scaning.
I recommend you to re-check that:
Check USB storage devices / removable drives
Download MCShield from one of the following links:
MyCity - Official download link
Softpedija - Mirror download link
[*] Double click MCShield-Setup to install the application.
[*] Wait a few seconds to MCShield finish initial scan.
Recommendation to under General and Scanner tab you click on Defaults button to choose recommended options.
[*] Connect your USB storage devices to the computer one at a time. Scanning will be done automatically.
When all scanning is done, you need to attach a logreport that MCShield has created.
Start → All Programs → MCShield → Logs
Attach here → AllScans.txt
Explanation: USB storage devices are all the USB devices that get their own partition letter at connecting to the PC,
e.g. flash drives (thumb/pen drives, USB sticks), external HDDs, MP3/MP4 players, digital cameras,
memory cards (SD cards, Sony Memory Stick, MultiMedia Cards etc.), some mobile phones, some GPS navigation devices etc.
all clean :-\
good. 
i recomend that you keep that tool MCShield … a special tool for USB malware
it is a install and forget tool, it auto updates and scan your usb device when you plug it in
