The error is being caused by a virus. Please download the latest definitions for your antivirus program and clean your hard drives and any other removable drives. Also do the following steps,

  • Scan the registry and find  the words ‘resycled’ and  ‘boot.com’ and delete the keys. Take a backup of  the  registry before doing so.
  • Scan and delete all files that state boot.com in the folder  ‘C:\Windows\system32\dllcache’
  • Scan and delete all files  that state boot.com in the folder ‘C:\Windows\prefetch’ or clear the  folder.
  • Clear  the  temp  folder, cookies, and Internet cache.
  • Disable  the Autorun  feature before accessing any external drives (USB flash drives, cameras, etc.) and CD/DVDs or just hold down [Shift] for 15 seconds when plugging in the drives. This will prevent the ‘autorun.inf’ file from executing the virus.
  • Do not double click on the drive letter, instead right-click and select  ‘Explore’ to open it.
  • Delete all files and folders with names ‘autorun.inf’ and  ‘resycled’  from all drives and folders.

Always keep your antivirus program up to date when using shared external media or if you download unknown software often. Keep Windows updated using the automatic update feature.
