Strange Folder created on July 27, 2099 !

Today, i was busy trasferring all my hard-Disk data to DVDs. After completing my transfer work, i was getting error in deleting my Song folder"mixws".
Checking the properties i found that my folder is created on July 27, 2099 ! That's quite strange....
It looks like there is some worm or virus behind this strange Creation Date.



Anyway, i m formatting my hard-Disk and reinstalling windows. So, it will not be a trouble for me anymore.
