I suggest that you install
Panda USB Vaccine for USB devices:
http://research.pandasecurity.com/panda-usb-and-autorun-vaccine/ and it can be run on any drive on your machine for removable devices.
You are given the option to "vaccinate" your machine, which means to disable autorun.inf malware from infecting your machine again (or in your case preventing further damage), and you can enable it again (although I wouldn't). Plus you can "vaccinate" any USB/flash or removable device so that it cannot infect your machine. This type of malware is easily transmittable because many people use USB's.
How to format or cleanse your USB / flash drive:
- Right click from Windows Explorer and do a full format to cleanse your USB flash drive.
You should also run the following:
1. Avast Boot-time scan after making sure your virus definitions are up to date.
2. MBAM (Malwarebytes)
· Download
free http://www.malwarebytes.org/ (the blue button) for an on-demand scanner.

o

· Once the program has loaded, select "Perform
FULL Scan", then click Scan.
· The scan may take some time to finish, so please be patient.
· When the disinfection scan is complete, a log will appear in Notepad and you may be prompted to Restart. (See Extra Note).
· Click the “
remove selected” button to quarantine anything found. You will find the infection details under the Quarantine tab.
· The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
