Flash_Disinfector.exe creates a hidden folder named autorun.inf in each partition and every external drive connected which helps protect all drives from future infection.
Flash (usb, pen, thumb, jump) drive infections usually involve malware that loads an autorun.inf file into the root folder of all drives (internal, external, removable). When the removable media is inserted, autorun looks for autorun.inf and automatically executes another malicious file to run on your computer. When a flash drive becomes infected, the Trojan will infect a system when the removable media is inserted if autorun has not been disabled.
"Autorun" is the feature built into Windows that automatically runs a program specified by an "autorun.inf" file whenever a CD-ROM, DVD or USB drive is plugged into a Windows-based computer. Autorun is intended as a convenience to automatically start an installer when removable media is inserted into the computer.
Keeping Autorun enabled on USB and other removable drives has become a significant security risk due to the increasing number of malware variants that can infect them and transfer the infection to your computer. Read Danger USB! Worm targets removable memory sticks.
You can hold down the Shift key when inserting the drive into your computer until Windows detects it to keep autorun.inf from executing automatically. However, I recommend disabling the Autorun feature on USB and removable drives as a method of prevention. This should keep the malicious file from automatically running upon insertion and infecting your system while allowing you to safely perform a scan.
The easiest way to disable Autorun on a specific drive is to download and use Tweak UI PowerToy.
If needed, see Disable Autorun/AutoPlay in XP with Tweak UI" for instructions with screenshots.
- After installation, launch Tweak UI, double-click on My Computer in the tree menu on the left, then click on AutoPlay > Drives. This will allow you to change the system settings for AutoPlay/autorun.
- Uncheck the drives you want to disable AutoPlay on and click on Apply.
- Next, click on the Types in the left tree. This allows you to control whether Autoplay is enabled for CD and DVD drives and removable drives. You may need to restart Tweak UI if it closes after step 2.
- Uncheck the box to disable Autoplay for a particular type of drive.
- Click Apply.
Note 1: When Autorun is disabled, double-clicking a drive which has autorun.inf in its root directory may still activate Autorun so be careful.
Note 2: Disabling autorun/autoplay does not prevent you from accessing your media sources. They are still available by opening My Computer and accessing the source drive (CD, DVD, usb/flash drive or external hard drive). Pictures on a camera can still be accessed through My Pictures and selecting "Get Pictures" from a scanner or camera. Media can also be accessed via the program you normally use it with such as music CDs accessed via Media Player, blank CDs via burning software, image handling software provided with the camera, etc. I strongly recommend you leave the autorun feature disabled and get into the habit of accessing your media devices manually.
