I just scan my usb with stinger and found trojan, however when I opened the folder there is "the folder is empty" message. Note however that in the explorer, the usb message that there is almost 50% files. Is there any way to retrieve the files?
Try the below steps and check to see if it helps
Open Folder Options > Control Panel > Classic View - Small Icons > Folder Options > Select View tab > Make sure that Show hidden files option is checked. Also uncheck Hide protected System files.
Re-insert Flash drive to see if you able to view your files. If yes copy the important files to your Hard Disk > Change the attributes that the files can be read ( Uncheck Hidden / Archive option) > Format your Flash drive after making sure you grabbed all important files. Re-copy the files that you had already.
Now the files will be visible in all machines and even though Show Hidden files options is Unchecked.
