Make the USB Flash Disk immune virus


Most malware now spreads via USB flash disk. What happens if you insert a USB flash disk to your computer? with the autorun is active every time we insert the flash disk to the computer we will always show the dialog box that contains some examples of menu options such as open folder to view files with any posts underneath using windows explorer. You should note the options that you want to click or see all the options there. If there are strange like that have any posts using application, Start My Apllication. using the program provided on the device under the open folder to view files that means you should be suspicious that the USB flash disk you have terjangkiti malware, and what happens if you run, or click any posts have ascertained your computer akan terjangkiti or malware is contagious.
That is one of the methods used to spread malware with USB flash disk. A program can run automatically when we insert the USB flash disk to the computer because in the flash disk is a file called autorun.inf. Malware will make it to transmit or spread themselves to a computer USB flash disk dicolok. But with a few tips from pcplus this, one of the spread of viruses via USB flash disk can be prevented.

The steps are as follows:


1. Create ekplorer windows that display all files, including files that are hidden. By using the facilities to Tools> Folder Options> View and then clear the Hide Extentions for known file types.
2. Open the USB flash disk (make sure it is free of virus) and delete the file called autorun.inf.
3. Create a new folder with the name autorun.inf
4. Open the folder you just created and create a txt file using notepad with the name of any kind. Then rename the files using characters from Japanese, Korean or Chinese
5. If you have installed Ms Office is on your computer Click Start> Programs> Accessories> System Tools> Character Map. Then select the font Arial Unicode MS, Scroll down until you find the character of Japan, Korea or China is.
6. Ganda click on the selected character as much as about 5 characters, and then click copy.

How Safe?
Because malware can not make a autorun.inf file in a folder in the windows, may not have the same file name is not it? autorun.inf file because we already use. In addition, malware can be removed from memory because most malware is not ready with the condition that we have created earlier so that there were "unhandled exception error" which will be removed from memory by windows. Making a text file with file names using characters from Japanese, Korean and Chinese are not without reason, as malware often does not support Unicode characters so that these characters are considered fixed and malwarepun Windows will fail to delete the text file.

The hope that useful.
