Hvis det er klez kan dette blive nødvendigt:
1. Download the FixKlez.com file from
http://securityresponse.symantec.com/avcenter/FixKlez.com.2. Save the file to a convenient location, such as your download folder or the Windows desktop (or, if possible, removable media that is known to be uninfected).
3. To check the authenticity of the digital signature, refer to the section The digital signature.
4. Close all programs.
5. If you are on a network or if you have a full-time connection to the Internet, disconnect the computer from the network and the Internet.
6. If you are running Windows Me or Windows XP, then disable System Restore. Refer to the section System Restore option in Windows Me/XP for additional details.
NOTE: If you are running Windows Me/XP, Symantec strongly recommends that you do not skip this step.
7. Restart the computer in Safe mode (all versions of Windows except Windows NT). For instructions, read the document for your version of Windows.
How to start Windows XP in Safe mode.
How to start Windows 2000 in Safe mode.
How to restart Windows 9x or Windows Me in Safe mode.
8. Double-click the FixKlez.com file to start the removal tool.
9. Click Start to begin the process, and allow the tool to run.
10. Restart the computer normally.
11. Next, you must reinstall NAV. For consumer products such as NAV 2000/2002/2002, follow the instructions in the document How to restore Norton AntiVirus after removing a virus. For Enterprise versions, contact your system administrator.
12. Run LiveUpdate to make sure that you are using the most current virus definitions, and scan the computer again. If NAV detects any infected files and cannot repair them, then choose to delete the files.
13. If you are running Windows Me/XP, re-enable System Restore.
NOTE:The removal procedure might be unsuccessful if Windows Me/XP System Restore was not disabled as previously directed because Windows prevents System Restore from being modified by outside programs. Because of this, the removal tool might fail. If W32.Klez.gen@mm was activated before you ran the removal tool, in most cases you will not be able to start Norton AntiVirus (NAV). The instructions for running NAV from the command line and reinstalling NAV are in the removal section of the W32.Klez.E@mm writeup.
When the tool has finished running, you will see a message that indicates whether the computer was infected by variants of W32.Klez@mm and/or variants of W32.ElKern. If an infection was removed, the program displays the following results:
The total number of the scanned files
The number of deleted files
The number of repaired files
The number of viral processes terminated
The number of viral services deleted
The number of registry entries fixed
The digital signature
FixKlez.com is digitally signed. Symantec recommends that you use only copies of FixKlez.com that were downloaded directly from the Symantec Security Response download site. To verify the authenticity of the digital signature, follow these steps:
1. Go to
http://www.wmsoftware.com/free.htm.2. Download and save the Chktrust.exe file into the same folder in which you saved FixKlez.com (for example, the C:\Downloads folder).
3. Depending on your version of Windows, do one of the following:
Click Start, point to Programs, and click MS-DOS Prompt.
Click Start, point to Programs, click Accessories, and then click Command Prompt.
Change to the folder that contains FixKlez.com and Chktrust.exe, and then type
chktrust -i FixKlez.com
For example, if the file exists in the C:\Downloads folder, enter the following commands:
cd\
cd downloads
chktrust -i FixKlez.com
Press Enter after you type each command. If the digital signature is valid, you will see the following:
Do you want to install and run "W32.Klez Fix Tool" signed on 5/16/2002 2:26 AM and distributed by Symantec Corporation.
NOTES:
The date and time that appear in this dialog box will be adjusted to your time zone if your computer is not set to the Pacific time zone.
If you are using Daylight Saving Time, the time that appears will be exactly one hour earlier.
If this dialog box does not appear, do not use your copy of FixKlez.com. It is not from Symantec.
4. Click Yes to close the dialog box.
5. Type exit and then press Enter to close the MS-DOS session.
System Restore option in Windows Me/XP
Windows Me and Windows XP users should temporarily turn off System Restore. This feature, which is enabled by default, is used by Windows Me/XP to restore files on your computer in case they become damaged. When a computer is infected with a virus, worm, or Trojan, it is possible that the virus, worm, or Trojan could be backed up by System Restore. By default, Windows prevents System Restore from being modified by other programs. As a result, there is the possibility that you could accidentally restore an infected file, or that online scanners would detect the threat in that location. For instructions on how to turn off System Restore, read your Windows documentation or one of the following articles:
How to disable or enable Windows Me System Restore
How to disable or enable Windows XP System Restore
For additional information and an alternative to disabling Windows Me System Restore, see the Microsoft Knowledge Base article Anti-Virus Tools Cannot Clean Infected Files in the _Restore Folder, Article ID: Q263455.
How to run the tool from a floppy disk
1. Insert the floppy disk that contains the FixKlez.com file into the floppy disk drive.
2. Click Start, and then click Run.
3. Type the following, and then click OK:
a:\fixklez.com
NOTES:
There are no spaces in the command a:\fixklez.com
If you are running Windows Me and System Restore remains enabled, you will see a warning message. You can choose to run the removal tool with the System Restore option enabled, or exit the removal tool.
4. Click Start to begin the process, and then allow the tool to run.
5. If you are running Windows Me, then re-enable System Restore.
NOTE: If you are using Norton AntiVirus (NAV) 2000/2001/2002, in most cases, after you remove the virus you must uninstall and reinstall NAV. For instructions on how to do this, read the document How to restore Norton AntiVirus after removing W32.Goner.A@mm or W32.Klez.gen@mm.
