Why flash disks to spread a computer virus? For more able to find out why the media often become the target virus FD course because of all the external data storage media progress, FD is the most dominant and most famous. The negative impact of this development can still be felt, the more frenzied penyebaranya virus mainly by the media. In a virus spread through the media is very easy, without having to run a virus infected file, the virus will spread automatically when the flash disk has been plugged into the computer.
Local virus did spread through the FD with the two techniques, the first technique to work when a file is opened by a user's pseudonym, and the second technique works automatically use the autoplay function in windows.
In the second technique, the virus makes a file autorun.inf on target FD. Autorun.inf is a file needed by windows to perform the function autoplaynya autoplaynya so if the function is active the automatic windows will read the autorun.inf and run the commands in the file.
Facilities autoplay on windows is a kind of facility that allows the call to automate the identification and initial program on removable media. This facility allows an Interactive CD to directly run the program early so the CD is inserted on the computer. Gap convenience is what ultimately used by viruses to spread themselves automatically.
Early Prevention Tips
How to prevent virus transmission by the second technique is actually very easy, that is by disabling windows autoplay facility. How can you read here:Enabling / disabling Windows AutoPlayHow-To Tuesday: Disable AutoRun on Windows!Disable Autoplay Windows 2000/XP
Moreover, it can use a program like tweak ui tweak windows or PowerToys for Windows.
However, this way my view is not an effective way, since most people leave windows autoplay function is active with a variety of reasons. Therefore, I think about how so I can know about the transmission of the virus in my flash disk. Finally I got the idea to put the first autorun.inf file on my UFD before the virus to use it. Be an early detection tool transmission of the virus on flash disk.
The steps to create an early detection tool is as follows:Open Notepad ProgramType the following command:
[Autorun]
icon = icon.ico
label = yourname
Yourname ** indicate the name of our FD, please be filled in accordance with the wishes, as well as Icon is the icon file you want to display, place the file in the root directory icon.ico FD.Save As with the File Name: autorun.inf Save As Type: All FilesStore in the root (outside the directory) UFD.Fox attributes we become readme file autorun.inf, hidden, and archive, the way to right click on the name autorun.inf file and select PROPERTIES, then Check the boxes for writing read-only, hidden and archive. Attribute SETTING IS IMPORTANT!
1.Alat early detection have become, now living doing the tests. Restart your computer, then plug the FD which already contain autorun.inf. Symbol icon and label on the flash disk will change according to what we have been setting.
You actually can do other variations on the autorun.inf commands, such as to run a program automatically on the UFD as in this article:
How to make a Windows AutoPlay CD
or use the autorun generator like this:CDInterface StudioAutorun Creator
Please do improvisation itself, probably by googling you find more variations.
How does this early detection tool? The way it works is very simple. If there are other autorun.inf file that will go to the UFD, then the computer system will issue a warning that the file will be overwritten as follows:
Answer NO, for the autorun.inf file is not overwritten with the new. Another sign of change is the autorun.inf on the drive icon will change by itself (not in accordance with what we are setting).
This is the function of early detection in fact, that if the warning appears, we must be careful because of the possibility of infiltration by a virus. But this does not apply if we are to install a program that contains autorun.inf like PortableApps Suite on the UFD.
Limitations of this tool:If the user answered YES to the file replace the warning, it will be replaced with the autorun.inf autorun.inf created by the virus. To overcome this there is a suggested use to make autorun.inf file but not as a folderMaker could have done a social engineering viruses so that does not appear to change the autorun.inf, to overcome this using Disk Utility USB utility software can give your immune FD.Cache icon on windows cause you can not find autorun.inf file changes quickly through the icon has changed. The operating system must be restarted in advance to eliminate the cache.There are automated programs windows version is a USB DISK SECURITY please download at: USB DISK SECURITY program prevents autorun file directly into your computer.
