The caller claims to represent Windows and says there is something wrong with my computer. Don't believe them! I've checked with my computer geek and he says they are not for real. They have never had access to my computer and won't unless I follow their instructions an inadvertantly give them access. Don't be fooled. The caller has a thick, hard to understand Indian accent. They called asking for me by my maiden name, so they must have gotten my name off a really old data base.
