Please can someone help me urgently. I recently discovered a Trojan.Anserin virus on my computer and I'm not sure how to get rid of it. I am currently using 'Norton Internet Security 2005' and 'Spybot Search and Destroy'. Please can some help. Thank you in advance

You need to turn system restore off(My Computer>properties) and restart the computer. During the restart enter the safe mode, select administrator and run your antivirus scan. Make sure that you run liveupdate manually to make sure that NAV has the latestdefinitions. HTH

Thanx for the assitance I found this on a website, I'm not sure whether it is advisable to follow this or not. In addition if I remove the virus successfully is there still a chance of it coming back, if so how can I avoid this happerning The document I found is below: The following instructions pertain to all current and recent Symantec antivirus products, including the Symantec AntiVirus and Norton AntiVirus product lines. 1. Disable System Restore (Windows Me/XP). 2. Update the virus definitions. 3. Run a full system scan and delete all the files detected as Trojan.Anserin. 4. Delete the value that was added to the registry. For specific details on each of these steps, read the following instructions. 1. To disable System Restore (Windows Me/XP) If you are running Windows Me or Windows XP, we recommend that you temporarily turn off System Restore. Windows Me/XP uses this feature, which is enabled by default, to restore the files on your computer in case they become damaged. If a virus, worm, or Trojan infects a computer, System Restore may back up the virus, worm, or Trojan on the computer. Windows prevents outside programs, including antivirus programs, from modifying System Restore. Therefore, antivirus programs or tools cannot remove threats in the System Restore folder. As a result, System Restore has the potential of restoring an infected file on your computer, even after you have cleaned the infected files from all the other locations. Also, a virus scan may detect a threat in the System Restore folder even though you have removed the threat. 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 turn off or turn on Windows XP System Restore" Note: When you are completely finished with the removal procedure and are satisfied that the threat has been removed, re-enable System Restore by following the instructions in the aforementioned documents. For additional information, and an alternative to disabling Windows Me System Restore, see the Microsoft Knowledge Base article, "Antivirus Tools Cannot Clean Infected Files in the _Restore Folder," Article ID: Q263455. 2. To update the virus definitions Symantec Security Response fully tests all the virus definitions for quality assurance before they are posted to our servers. There are two ways to obtain the most recent virus definitions: * Running LiveUpdate, which is the easiest way to obtain virus definitions: These virus definitions are posted to the LiveUpdate servers once each week (usually on Wednesdays), unless there is a major virus outbreak. To determine whether definitions for this threat are available by LiveUpdate, refer to the Virus Definitions (LiveUpdate). * Downloading the definitions using the Intelligent Updater: The Intelligent Updater virus definitions are posted daily. You should download the definitions from the Symantec Security Response Web site and manually install them. To determine whether definitions for this threat are available by the Intelligent Updater, refer to the Virus Definitions (Intelligent Updater). The Intelligent Updater virus definitions are available: Read "How to update virus definition files using the Intelligent Updater" for detailed instructions. 3. To scan for and delete the infected files 1. Start your Symantec antivirus program and make sure that it is configured to scan all the files. * For Norton AntiVirus consumer products: Read the document, "How to configure Norton AntiVirus to scan all files." * For Symantec AntiVirus Enterprise products: Read the document, "How to verify that a Symantec Corporate antivirus product is set to scan all files." 2. Run a full system scan. 3. If any files are detected as infected with Trojan.Anserin, click Delete. Note: If your Symantec antivirus product reports that it cannot delete an infected file, Windows may be using the file. To fix this, run the scan in Safe mode. For instructions, read the document, "How to start the computer in Safe Mode." Once you have restarted in Safe mode, run the scan again. After the files are deleted, restart the computer in Normal mode and proceed with section 4. 4. To delete the value from the registry Important: Symantec strongly recommends that you back up the registry before making any changes to it. Incorrect changes to the registry can result in permanent data loss or corrupted files. Modify the specified subkeys only. Read the document, "How to make a backup of the Windows registry," for instructions. 1. Click Start > Run. 2. Type regedit Then click OK. 3. Navigate to the subkey: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon 4. In the right pane, set the value: "Shell" = "Explorer.exe" 5. Navigate to the subkey: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run 6. In the right pane, delete the value: "Shell" = ""C:\Program Files\Common Files\Microsoft Shared\Web Folders\ibm[random 5 digit number].exe"" 7. Exit the Registry Editor.

It should not come back. The problem with system restore is that Trojans/worms/viruses love to reside in those files. This is why every time you start the computer again the Trojan reappears.

Personally, I would like to thank you very much for your help, but do you reckon I should delete the value from the registry or not. and when i finish getting rid of the trojan shall I turn back on system restore or not? These are the instructions below: 4. To delete the value from the registry Important: Symantec strongly recommends that you back up the registry before making any changes to it. Incorrect changes to the registry can result in permanent data loss or corrupted files. Modify the specified subkeys only. Read the document, "How to make a backup of the Windows registry," for instructions. 1. Click Start > Run. 2. Type regedit Then click OK. 3.

I would follow Symantec's instructions. There is a chance that it may not be in the registry. If I did not see it, I would leave things alone. There are a few occasions that system restore can get you out of a jam. I do not have it turned on. If I did I would set the slider to 4-5%, instead of the default 12% to save space on a larger hard drive that most of us have now. After you think the system is clean, I would go to; http://www.kaspersky.com/virusscanner just to make sure it is gone. HTH

Thanks, one last thing what do you mean you will leave it alone if you did'nt see it. What do you mean, sorry about this I just don't want to make damage my laptop permanately. Oh and is that software you reccommended me good and is the software free Sorry for all the questions
