Hello,
today i had the displeasure of discovering that one of my usb sticks was infected with a worm (strange considering it hasn't spent much time being plugged in into my PC). All should be good now, and the threats are removed. But that still leaves me with my files that are now unusable; i can't open them. Their thumbnails have changed to those of jpeg-files (they were regular folders), and the file extensions are now all .exe.
The worm was, i believe, called xoujaw (that was the only file whose name i didn't recognize).
Any help would be appreciated!
