The Win 32/Kryptik Trojan horse slows down your PC's performance and can potentially collect and use your e-mail address for the purpose of spamming others. Removing the program requires a virus checker or manually deleting certain files.

Instructions

  1. 1

    Download PC Safe Doctor (see Resources). Run the downloaded program after installing.

  2. 2

    Select "Online Scan" to start the scan of your computer. After the scan is done, select "Remove" if the "Win32.Kryptik.FGR" file is found.

  3. 3

    Remove manually if PC Safe Doctor misses the file. Restart your computer and hold "F8" as it reboots. Select "Safe Mode with Networking" and start up your computer.

  4. 4

    Open the Windows Task Manager by pressing "Ctrl," "Alt" and "Delete." Select "Task Manager." Stop the program titled "Win32/Kryptik.NGH." Go to the Control Panel, select "Add/Remove Programs," and select "Win32/Kryptik.NGH" to uninstall it.

  5. 5

    Open the Registry Editor. Press the "Start" button and choose "Run." Type "regedit" into the box. Open the "HKEY_CURRENT_USER" folder and delete the following entries:

    "Software\Microsoft\Windows\CurrentVersion\Internet Settings 'WarnonBadCertRecving' = '0'"

    "Software\Microsoft\Windows NT\CurrentVersion\Winlogon 'Shell' = '%UserProfile%\Application Data\antispy.exe"

    "Software \Microsoft\Windows\CurrentVersion\Policies\ Explorer\Run"

    "Software\Microsoft\Windows\CurrentVersion\Policies\Attachments 'SaveZoneInformation' = '1'"

    "Software\Microsoft\Windows\CurrentVersion\Policies\Associations 'LowRiskFileTypes' = '.exe'"

  6. 6

    Open the "HKEY_LOCAL_MACHINE" folder. Delete the registries "SOFTWARE\Paladin Antivirus" and "SOFTWARE\Malware Defense." Search your registries for any "Win32.Kryptik.FGR" files, as it can hide in both the WIN.INI file and the strings "run=" and "load=." Reset your computer.

  7. 7

    Clean the temporary files from your Internet browsers. Run PC Safe Doctor to ensure all elements of the program are gone.
