Files and folders in Flashdisk suddenly lost

Some time ago, I asked a friend to check that he said flasdisk data suddenly disappeared. Each open each folder so it will go back to the folder or openother folders in new windows, and the folder is always empty. After I scan the computer with SMADAV + ESET NOD32, finally found a lot of virus, and found the viruses that duplicate themselves with icon and name of the folder in question, so when you open the folder actually carry the virus. While the original folder is hidden. This can cause the computer to become infected because act of user who is not particularly careful with the flash storage media that have been exploring many computers.

Antivirus can only remove virus earlier but could not restore the files or folders are hidden, some antivirus software may be able to do this. To show hidden folders, not just through the Folder Options>View>Show hidden files and folders, but it should uncheck "Hide protected operating system files (Recommended)" and sometimes the menu is removed by a virus, so that we can not change it.

Once the folder is displayed, the icon will appear faintly showing files / folders are hidden if the right click>Properties, then Hidden option will not be changed (because of hidden system). To display it again can be done with the following steps:

1. Open Command Prompt (All Programs>Accessories>Command Prompt)

2. Find where the shared folder hide

3. Type command attrib *.* -S -H -R /S /D

4. To find out information about the order type attrib /?

After opening a Command Prompt window, it usually will appear as follows:

C:\Documents and Settings\ user_name

Then just type in the following

CD / and press enter.

C: \>

Next, find where the files / folders are hidden. If the drive E:, then just type the following command:

C: \>E: and press enter, so it will appear E: \>

After that type in the above command attrib *.* -S -H- R /S /D, which means that all files and folders on drive E: which is hidden will be displayed. If only a specific folder, for example in the folder D:\Data\Doc. Then the following steps:

1. Change the location to the drive D Command prompt, by typing the command D:

2. To reach the location D:\Data\Doc, then type the following command:

CD Data\Doc

3. Then just write the command attrib *.* -S -H -R /S /D
