[virus] w32.kitro.c.rowm

[vandenhende]

Ik heb dit virus op mijn computer: w32.kitro.c.worm Ik heb Norton antivirus 2002 erop staan. Voorzien van laatste updates. Op de een of andere manier had hij auto-protect uitgeschakeld. Ik kan het virus niet in quarantaine zetten of verwijderen. Er zijn 2 bestanden geinfecteerd, nl: cristo~1.cpl en nog een vergelijkbaar bestand met zelfde extensie.

Wie kan mij vertellen hoe ik van dit virus afkom zonder mijn computer te formatteren, en
Wie kan mij vertellen wat die extensie .cpl precies inhoud. Deze ken ik nl niet.

Bedankt!

die heb ik ook net 2x binnen gekregen, maar Quick Heal X donderde ze er netzosnel weer af, maar de .cpl bestandjes staan in je temp-email directory en zijn als het goed is nog niet geactiveerd

gewoon ff met norton een scan doen en dan kwakt ie ze er wel weer af

Probeer eens of je die worm aan de hand van [url="http://securityresponse.symantec.com/avcenter/venc/data/w32.kitro.c.worm.html"]deze[/url] link kan verwijderen.

CPL = Control Panel Extension: dat zijn die mooie pictogrammen bij je configuratiescherm. Zoals tweakui, systeem, geluid enz enz

[url="http://housecall.antivirus.com/housecall/start_corp.asp"]http://housecall.antivirus.com/housecall/start_corp.asp[/url] misschien kan je het via die online virusscanner ook fixen.

Compromises security settings: deletes files necesary to certain AV products 
Distribution 

Subject of email: varies 
Name of attachment: varies 
Size of attachment: 236,032 bytes 


W32.Kitro.C.Worm arrives by email as an attachment with the .cpl (Control Panel Applet) extension. When executed, it does the following:

It copies itself to the root of the hard drive and to the windows folder (the windows folder is usually c:\windows or c:\winnt). The file name that it uses is a random number with the .cpl extension, for example 1708.cpl.

In order to run each time the machine is rebooted, it adds a value to the key

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run

The value refers to the file that it copied previously, for example

1708     rundll32.exe shell32.dll,Control_RunDLL C:\WINDOWS\1708.cpl

W32.Kitro.C.Worm collects email addresses of the user's MSN messenger contacts from the registry key

HKEY_CURRENT_USER\Software\Microsoft\MessengerService\ListCache\.NET Messenger Service

and attempts to send itself through the SMTP server mail.hotmail.com. The characteristics of the email message are described below. After successfully sending itself, W32.Kitro.C.Worm creates a copy of itself under the name zero.exe in the windows directory.

W32.Kitro.C.Worm uses temporary files named commfig.sys and k32.vxd and located in the windows directory during the manipulation of email addresses lists.

W32.Kitro.C.Worm also attempts to spread through the Kazaa peer-to-peer network. It tries to read the registry value

HKEY_CURRENT_USER\Software\Kazaa\Transfer\DlDir0

and if it can do so, it copies itself to the Kazaa share under one of the following names, thus making itself available for other Kazaa users to download.

In order to evade detection by some antivirus products, W32.Kitro.C.Worm manipulates data files and registry information. It modifies the registry value

HKEY_LOCAL_MACHINE\SOFTWARE\KasperskyLab\SharedFiles\Folder

to point to the windows directory and alters the value

PAV.EXE     C:\WINDOWS
in
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run

probably in an attempt to prevent an antivirus program from running on startup.

In addition it deletes the following files if they are present on the system:

C:\archiv~1\perav\pav.dll
C:\archiv~1\perav\per.dll
C:\program files\perav\pav.dll
C:\program files\perav\per.dll

and also the following files from the windows folder:

PAV.EXE
\bases\avp.set
\system\vshield.vxd
\system32\vshield.vxd
\vshield.vxd

W32.Kitro.C.Worm contains several possible email formats, using various subject lines and file attachments.

Symantec Security Response encourages all users and administrators to adhere to the following basic security "best practices":

Turn off and remove unneeded services. By default, many operating systems install auxiliary services that are not critical, such as an FTP server, telnet, and a Web server. These services are avenues of attack. If they are removed, blended threats have less avenues of attack and you have fewer services to maintain through patch updates. 
If a blended threat exploits one or more network services, disable, or block access to, those services until a patch is applied. 
Always keep your patch levels up-to-date, especially on computers that host public services and are accessible through the firewall, such as HTTP, FTP, mail, and DNS services. 
Enforce a password policy. Complex passwords make it difficult to crack password files on compromised computers. This helps to prevent or limit damage when a computer is compromised. 
Configure your email server to block or remove email that contains file attachments that are commonly used to spread viruses, such as .vbs, .bat, .exe, .pif and .scr files. 
Isolate infected computers quickly to prevent further compromising your organization. Perform a forensic analysis and restore the computers using trusted media. 
Train employees not to open attachments unless they are expecting them. Also, do not execute software that is downloaded from the Internet unless it has been scanned for viruses. Simply visiting a compromised Web site can cause infection if certain browser vulnerabilities are not patched. 


NOTE: These instructions are for all current and recent Symantec antivirus products, including the Symantec AntiVirus and Norton AntiVirus product lines.


1. Update the virus definitions, run a full system scan, and delete all files that are detected as W32.Kitro.C.Worm
2. Delete the value that looks similar to

rundll32.exe shell32.dll,Control_RunDLL C:\WINDOWS\1708.cpl

from the registry key

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run>
3. Also delete the value

  PAV.EXE     C:\WINDOWS

  from the regsitry key

  HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run

For details on how to do this, read the following instructions.

NOTE: Before proceeding, 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 outside programs. As a result, there is the possibility that you could accidentally restore an infected file, or that on-line 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

To scan for and delete the infected files:
1. Obtain the most recent virus definitions. There are two ways to do this:
Run LiveUpdate, which is the easiest way to obtain virus definitions. These virus definitions have undergone full quality assurance testing by Symantec Security Response and are posted to the LiveUpdate servers one time each week (usually Wednesdays) unless there is a major virus outbreak. To determine whether definitions for this threat are available by LiveUpdate, look at the Virus Definitions (LiveUpdate) line at the top of this write-up.
Download the definitions using the Intelligent Updater. Intelligent Updater virus definitions have undergone full quality assurance testing by Symantec Security Response. They are posted on U.S. business days (Monday through Friday). They must be downloaded from the Symantec Security Response Web site and installed manually. To determine whether definitions for this threat are available by the Intelligent Updater, look at the Virus Definitions (Intelligent Updater) line at the top of this write-up.

Intelligent Updater virus definitions are available here. For detailed instructions on how to download and install the Intelligent Updater virus definitions from the Symantec Security Response Web site, click here.

2. Start your Symantec antivirus software and make sure that it is configured to scan all files. 
Norton AntiVirus Consumer products: Read the document How to configure Norton AntiVirus to scan all files.
Symantec Enterprise antivirus products: Read the document How to verify a Symantec Corporate antivirus product is set to scan All Files.
3. Run a full system scan.
4. If any files are detected as infected by W32.Kitro.C.Worm, click Delete.


To remove the values from the registry:

CAUTION: Symantec strongly recommends that you back up the registry before you make any changes to it. Incorrect changes to the registry can result in permanent data loss or corrupted files. Modify only the keys that are specified. Read the document How to make a backup of the Windows registry for instructions. 

1. Click Start, and click Run. The Run dialog box appears.
2. Type regedit and then click OK. The Registry Editor opens.
3. Navigate to the following key:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run

4. In the right pane, locate the value that looks similar to the following example and delete it:

rundll32.exe shell32.dll,Control_RunDLL C:\WINDOWS\1708.cpl

5. Next, Navigate to the following key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run

6. In the right pane, locate the value that looks similar to the following example and delete it:

PAV.EXE     C:\WINDOWS

7. Click Registry, and click Exit.


 


Revision History: 

NOTE: Definitions prior to July 8th 2002 may detect this threat as W32.Duni.Worm.

Die hele uitleg staat ook in de link die Garfield al aangaf.

[Zeepoog]

geloof mij, ik word al maanden dood geëmailed met die mailtjes.. het is dat ik er nu vanavond 's naar ging zoeken op gathering.tweakers. die attachments zijn steeds 312 kb groot, en ze komen door de mcafee virusscan van hotmail heen. Ik heb bewust mijn norton geüpdate, en gekeken of 'r nu echt 'n virus actief was.. en ja hoor, ik downloaden en norton meteen: geen toegang tot bestand: virus gevonden.. Échhhht héél slordig van mcafee dat ie nog steeds door hotmail heenkomt!!!

Als je nu de het bericht van gpvelzen of de tekst in de link van garfield goed leest, dan weet je ook hoe je het virus moet verwijderen als dat niet met de virusscanner lukt.
