Local viruses have one peculiarity that is rarely found on foreign-made computer pests. A Virus or worm out usually make use of the internet for spreading. Another case with a local virus. Its creator is often designed so that the virus can reproduce through the mediation of the usb disk, be it a flash disk or portable hard disk. This may be because in Indonesia are generally data exchange via a portable medium much easier to do.
I myself had a chance to get acquainted with the two types of viruses that spread via the local usb disk. Fortunately both are relatively tame, unlike the famous ferocious virus Brontok. And more lucky again two types of virus that I encountered on other people's computers.
Both have the same transmission method: via flash/portable disk. The mode takes also the same, i.e., by leveraging the Windows autorun feature.

Both have the same transmission method: via flash/portable disk. The mode takes also the same, i.e., by leveraging the Windows autorun feature.
Autorun feature (or autoplay) is actually intended for medium such as CD-ROM or DVD, so that the computer can directly execute the program (usually installer) in the optical disc when inserted. Autorun feature is enabled by the computer infected with Autorun.inf file with writeINF to the flash disk. These files are hidden (hidden) contrived and converted its status becomes read-only.
File AUTORUN.INF contains commands to execute other files in the form of programs that are also entered by computer contracting. This Program can be written in Visual Basic (this means we can read your own code), or in the form of binary executable files. The second file is in charge of infecting other computers. Then when the USB disk is first plugged it into the USB slot, and the computer detects the file AUTORUN.INF he will read it and then run the command run the program penular. Of the two events I encountered an antivirus program that is installed does not warn the existence of viruses in the flash disk.
Remove and prevent virus
Treat your computer already contracted the virus rather troublesome. Fortunately cleared the USB disk and ward off penjalarannya on a computer that is still clean quite easily. In both cases I found this transmission mechanism when using a USB disk on a computer that is running a non-Windows operating system (in this case, Fedora 7).
So far Fedora 7 and other distributions of Linux (and Mac OS) are immune from the virus Windows. Because it is quite safe to use non-Windows systems for cleaning the virus from autorun feature that utilizes the USB disk. Open the AUTORUN.INF file..INF FILE using a text editor, and then from there find the file which will be executed automatically. Find and delete these files. The last delete Autorun.inf file too.
Penangkalan this virus on my computer Windows is quite clear: turn off the autorun feature. This will not fully guarantee transmission through computer immune from USB disk, but it will ward off But how?
Users of Windows XP can download Tweak UI, which is one of Microsoft's Power Toys utility from http://www.microsoft.com/windowsxp/downloads/powertoys/xppowertoys.mspx
Click TweakUIPowerToySetup file to install the utility. When you're done launches Tweak UI. In the left pane of the application window, select My Computer, and then select Types. Clear the box next to Enable Autoplay for removable drives, and then click Apply. If you want you can also disable the option Enable Autoplay for CD and DVD drives.4.5
