betennis, It appears that your computer may have picked up a variant of the VBS.LoveLetter Worm. See the link below and you may want to post this in the Virus & Security forum.
I found all my pictures like the jpg files automatically turned into to the VBScript script files? I found the extention of the jpg. files had been added and changed to *.jpg.vbs format. I don't want to lose all my precious photos in my computer. If anyone can give me a tips or what I should do to get the files recover.
