Explanation :

Locknut.E is a malicious SIS file trojan that pretends to be patch for Symbian Series 60 mobile phones.

Disinfection with two Series 60 phones

  2. Put the memory card with F-Locknut into infected phone
  3. Start up the infected phone, the application menu should work now
  4. Go to application manager and uninstall the SIS file in which you installed the locknut variant
