Virus Removal Techniques

Special Case: Removing Kinza virus

Initial Symptoms:
  • The removable drive (pen drive) with the windows explorer icon
Source Files at the system
  • %systemroot%\system32\boot.vbs
  • %systemroot%\system32\imapd.exe and its variants

Removal

  • Kill the process dxdlg, wscript, imapd from process explorer
  • Remove the entry boot.vbs, wproxp, imapd from the logon tab of tool autoruns
  • Remove the files
  • %systemroot%\system32\wproxp.exe %systemroot%\system32\imapd.exe %systemroot%\system32\imapdb.exe %systemroot%\system32\imapde.dll %systemroot%\system32\imapdd.dll %systemroot%\system32\imapdc.dll %systemroot%\system32\imapdb.dll %systemroot%\system32\Kinza.exe
  • Some variants of imapd are not deleted (giving the message access denied) but they can be renamed and delted afterwards
Alternatively
  • You can run these scripts from the command line
  • Make sure your system is Windows XP, otherwise these scripts will force you not to login the system once you run them and logout (esp. in Windows 2000 and 98)
