So far, these are the issues. And the only solution I gave was this.
I also have found another simple solution. It may apply to those who can't open the cmd for i-don't-know-the-reason, or those who have difficulty to understand what I wrote back then (though I think I wrote it simple and plain) that they can't get the same result as the other had.
First, open the NOTEPAD. Then, type,
attrib -s -h /s /d *.*
Then save it as whatever-name-you-desire.bat (eg: unhide.bat).
You'll have this kind of file.
It is better to save and locate the file into the infected folder/ usb drive or you can save it somewhere else and then copy the file to the infected folder.
After that, double click the new batch file and... MAGIC!
Just for reminder, don't copy the file in your system folder or else, when you run this file, it will cause all the suppose hidden folders to be shown. It is safe to save & keep it in the desktop.
Aaand, some credits go to certain readers. Thanks for sharing your thought about this matter ~(^.^~)(~^.^)~
Say, this did not work the way it's supposed to, then you can either download any softwares to recover hidden files such as Altap Salamander ~I used this, long time ago, you can rely on it~, iReset ~i never try this~, or whatever software which I believe you can find if you search for it or format the drive ~as last resort~.
P/S : Seriously, my blog is full of crap!
