Discovered on: January 19, 2004
Last Updated on: April 26, 2004 03:06:30 PM
Symantec antivirus products exclusively use the virus name Bloodhound.Packed when a potentially unknown virus is found using Symantec Bloodhound technology. Bloodhound technology consists of heuristic algorithms used to detect unknown viruses. The actual file detected under Bloodhound.Packed is likely to be infected with a new, packed, 32-bit Windows virus.
Bloodhound.Packed is detected only in Portable Executable (PE) files. Bloodhound.Packed can detect any threat within a packed file.
Type: Trojan Horse, Virus, Worm
Infection Length: various
Systems Affected: Windows 2000, Windows 95, Windows 98, Windows Me, Windows NT, Windows Server 2003, Windows XP
Systems Not Affected: DOS, Linux, Macintosh, OS/2, UNIX

Submit samples detected as Bloodhound.Packed to Symantec Security Response so that these new viruses and variants can be identified and assigned specific names. Then, we can analyze them and provide more information about their nature.
To learn how to submit a file, read the document for the type of Symantec antivirus product you are using:
Consumer products: If you are using a Symantec antivirus consumer product, such as Norton AntiVirus 2004, click here.
Enterprise products: If you are using a Symantec antivirus enterprise (corporate) product, such as Norton AntiVirus Corporate Edition 7.0, click here.
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.
The following instructions pertain to all current and recent Symantec antivirus products, including the Symantec AntiVirus and Norton AntiVirus product lines.
Disable System Restore (Windows Me/XP).
Update the virus definitions.
Restart the computer in Safe mode or VGA mode.
Run a full system scan and delete all the files detected as Bloodhound.Packed.
Clear the Temporary Internet Files folder, if required.
For specific details on each of these steps, read the following instructions.
1. Disabling 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. Updating 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 on U.S. business days (Monday through Friday). 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. Restarting the computer in Safe mode or VGA mode
Shut down the computer and turn off the power. Wait for at least 30 seconds, and then restart the computer in Safe mode or VGA mode.
For Windows 95, 98, Me, 2000, or XP users, restart the computer in Safe mode. For instructions, read the document, "How to start the computer in Safe Mode."
For Windows NT 4 users, restart the computer in VGA mode.
4. Scanning for and deleting the infected files
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."
Run a full system scan.
If any files are detected as infected with Bloodhound.Packed, click Delete. If infected files are detected in the Temporary Internet Files folder, you may not be able to delete them. In this case, write down the full path and file name. Then, after restarting in Normal mode (see next step), follow the instructions in section 5.
Restart the computer in Normal mode. For instructions, read the section on returning to Normal mode in the document, "How to start the computer in Safe Mode."
5. To clear the Temporary Internet Files folder, if required
Log onto the computer using the name that was shown in the path that you wrote down in step 4c.
For example, if the path was:
C:\Documents and Setting\Linda\Local Settings\Temporary Internet Files\qrwmqczd.dll
log onto the computer as Linda.
Start Internet Explorer.
Click the Tools menu > Internet Options.
In the Temporary Internet Files section, click the Delete Files button.
Check "Delete all offline content," and then click OK.
Additional information:
What are Portable Executable (PE) files?
Portable Executable (PE) files are files that are portable across all the Microsoft 32-bit operating systems. The same PE-format executable can be executed on any version of Windows 95, 98, Me, NT, 2000, and XP. All the PE files are executable, but not all the executable files are portable.
A common example of a PE file is a screen saver (.scr) file.
