Overview

This is a virus detection. Viruses are programs that self-replicate recursively, meaning that infected systems spread the virus to other systems, which then propagate the virus further. While many viruses contain a destructive payload, it's quite common for viruses to do nothing more than spread from one system to another.

Aliases

• Neworld.PHP

• PHP.Newworld

• PHP_NEWWORLD.A

Characteristics

This is the second known PHP virus to be discovered. PHP is a server-side scripting language used to generate dynamic Web page content.

When a script containing the virus is run, it may display the following message:

Neworld.PHP
Welcome To The New World Of PHP Programming

This script virus is coded to look in the path C:\WINDOWS for host files of these extensions: .php, .html, .htm or .htt. If the files are not read-only, they are considered viable to the script virus.

Symptoms

When a script containing the virus is run, it may display the following message:

Neworld.PHP
Welcome To The New World Of PHP Programming

The script also contains these comments which are not displayed:

Method of Infection

This script virus is coded to look in the path C:\WINDOWS for host files of these extensions: .php, .html, .htm or .htt. If the files are not read-only, they are considered viable to the script virus.

Each file is opened and checked for the string "neworld.php" - not finding this string, the script attempts to insert a server-side include at the end of that file which instructs PHP to serve the content of the original viral file at the end of that file.

Removal

All Users :
Script,Batch,Macro and non memory-resident:
Use current engine and DAT files for detection and removal.

PE,Trojan,Internet Worm and memory resident :
Use specified engine and DAT files for detection. To remove, boot to MS-DOS mode or use a boot diskette and use the command line scanner:

Additional Windows ME/XP removal considerations

Users should not trust file icons, particularly when receiving files from others via P2P clients, IRC, email or other mediums where users can share files.

AVERT Recommended Updates :

* Office2000 Updates

* Malformed Word Document Could Enable Macro to Run Automatically (Information/Patch )

* scriptlet.typelib/Eyedog vulnerability patch

* Outlook as an email attachment security update

* Exchange 5.5 post SP3 Information Store Patch 5.5.2652.42 - this patch corrects detection issues with GroupShield

For a list of attachments blocked by the Outlook patch and a general FAQ, visit this link .
Additionally, Network Administrators can configure this update using an available tool - visit this link for more information .

It is very common for macro viruses to disable options within Office applications for example in Word, the macro protection warning commonly is disabled. After cleaning macro viruses, ensure that your previously set options are again enabled.
