in my pendrive, all folders & files turns into hidden files & folders ( which I can't see through enabling option in "folder search option" due to some sort of virus. avast cleaned some viruses, but hidden file problem remain intact.
then I used recovery software, & as a result i got back my files back with some virus file too & then avast av clean some files.
BUT my question is why I had to use recovery software & why avast av failed to sort out hidden file problems ??
