Three years on and Conficker (also known as Downup, Downadup and Kido) is still the most common virus threat.

Since November 2008 it’s infected computers across the globe, consuming network traffic and opening a back door to other malware attacks.

Conficker exploits unprotected computers and weak passwords.  Today it’s often spread through infected USB storage devices.

To prevent infection, Sophos recommends:

  • Apply the MS08-67 patch
  • Disable file and print sharing
  • Strengthen your password
  • Turn off autorun for USB devices
  • Apply a device control policy
