Solution:

Identifying the Malware Program

To remove this malware, first identify the malware program.

1. Scan your computer with your Trend Micro antivirus product.
2. NOTE the path and file name of all files detected as WORM_XPBAGUIO.A.

Trend Micro customers need to download the latest virus pattern file before scanning their computer. Other users can use Housecall, the Trend Micro online virus scanner.

Terminating the Malware Program

This procedure terminates the running malware process. You will need the name(s) of the file(s) detected earlier.

If the process you are looking for is not in the list displayed by Task Manager, proceed to the succeeding solution set.

1. Open Windows Task Manager.
   • On Windows 98 and ME, press
   CTRL+ALT+DELETE
   • On Windows NT, 2000, XP, and Server 2003, press
   CTRL+SHIFT+ESC, then click the Processes tab.
2. In the list of running programs*, locate the malware file(s) detected earlier.

5. To check if the malware process has been terminated, close Task Manager, and then open it again.
6. Close Task Manager.

*NOTE: On computers running Windows 98 and ME, Windows Task Manager may not show certain processes. You can use a third party process viewer such as Process Explorer to terminate the malware process.

On computers running all Windows platforms, if the process you are looking for is not in the list displayed by Task Manager or Process Explorer, continue with the next solution procedure, noting additional instructions.
