and some file become hidden..?
and the file can't be restore to normal after viruses have been clean..?
try this manner maybe can fix your problem.. I hope it works..
1. if you confuse about using attrib in cmd, see the help with write
help attribin cmd (Windows command line)
2. Now go to the flashdisk directory and just write
attrib -R -A -S -H /S /D
and wait a moment..
all the hidden file will be restore to normal.
*) why using (-) ..?
--> just because it mean to be restore. the plus (+) mean to make the file to be hidden, be a system file etc.
