![]() ![]() Even if you have disabled autorun options yourself, it is possible for registry software or tweaking programs to change the setting without your knowledge. Even if your own machine might be invulnerable to the Autorun virus threats, it doesn’t automatically mean other peoples PC’s are as well, especially if they are running a pure Windows 7 operating system. Other versions of Windows received a hotfix patch from Microsoft to behave in a similar way some time ago. Windows 7 and 8 have Autorun disabled by default for all devices except CD/DVD media although the slightly different Autoplay function can still be used on USB devices. It would come as no surprise to anyone that Autorun based threats have been one of the most common forms of infection over recent years. The ease at which these viruses can then travel from system to system with the aid of the unwitting user poses a major security risk. This is because of the ease at which the Autorun.inf can be replaced and then pointed to start a malicious executable, and begin the infection as soon as the device is inserted into a machine. With the invention of USB flash drives and hard drives, the Autorun feature has been the target of attack from viruses, Trojans and other malicious software.

For example, Panda Security's USB Vaccine can be set to "vaccinate" removable storage devices automatically, can auto-start on Windows reboot and has a resident mode, which means it can run hidden in the background. We were told the tool will be improved in the future, but for now it lacks features found in alternatives provided by other antivirus vendors. Fortunately, BitDefender researchers haven't yet identified any malware that attempts to recursively delete this folder from USB storage devices. The bad news is that bypassing this protection mechanism is as simple as removing the autorun.inf folder created by the tool. The reasoning behind this procedure is to prevent AutoRun malware from creating the rogue autorun.inf files which it requires for propagation. It contains a sub-folder and two empty files. This creates a folder called autorun.inf with read only, hidden and system attributes on the device. There is a drop-down list which allows users to select the device and press an immunize button. The second option offered by the program is to immunize removable storage devices plugged into the computer. ![]() Leaving the interface quirks aside, the computer immunization is achieved by modifying a special registry key to disable AutoRun for all devices except optical ones (CD/DVD-ROMs). ![]() Most people would presume that ON is for "yes, immunize my computer" and OFF is for no, but apparently it's the other way around because the switch refers to the state of AutorRun. The control to do this is a bit confusing because the user is asked if they want to immunize the computer and are presented with an ON/OFF switch. One is to immunize the computer, the equivalent of disabling the malware-abused AutoRun Windows feature. It comes as a single executable which provides a simple user interface. Romanian antivirus vendor BitDefender has released a free tool designed to protect computers and removable storage devices from AutoRun malware.ĭubbed BitDefender USB Immunizer the application doesn't require any installation.
