Why Is It Important to Remove Malware Files?^

It is imperative that you delete malware-associated files as soon as possible because they can be used - or are already being used - to inflict serious damage on your PC, including:

  • Disrupting the normal functioning of the operating system or rendering it completely useless.
  • Hijacking valuable private information (credit card numbers, passwords, PIN codes, etc.)
  • Directing all your Web searches to the same unwanted or malicious sites.
  • Dramatically slowing down your computer.
  • Gaining total control of your PC to spread viruses and trojans and send out spam.

How to Remove yahoo.xml^

  1. To enable deleting the yahoo.xml file, terminate the associated process in the Task Manager as follows:
    • Right-click in the Windows taskbar (a bar that appears along the bottom of the Windows screen) and select Task Manager on the menu.
    • In the Tasks Manager window, click the Processes tab.
    • On the Processes tab, select yahoo.xml and click End Process.
  2. Using your file explorer, browse to the file using the paths listed in Location of yahoo.xml and Associated Malware.

  4. Click Yes in the confirm deletion dialog box.
  5. Repeat steps 2-4 for each location listed in Location of yahoo.xml and Associated Malware.
  6. Notes:

    • The deletion of yahoo.xml will fail if it is locked; that is, it is in use by some application (Windows will display a corresponding message). For instructions on deleting locked files, see Deleting Locked Files.
    • The deletion of yahoo.xml will fail if your Windows uses the NT File System (NTFS) and you have no write rights for the file. Request your system administrator to grant you write rights for the file.

Deleting Locked Files^

You can delete locked files with the RemoveOnReboot utility. You can install the RemoveOnReboot utility from here.

After you delete a locked file, you need to delete all the references to the file in Windows registry.

To delete a locked file:

  1. Right-click on the file and select Send To -> Remove on Next Reboot on the menu.
  2. Restart your computer.

The file will be deleted on restart.

Note: In the case of complex viruses that can replicate themselves, malware files can reappear in the same locations even after you have deleted those files and restarted your computer. Exterminate It! Antimalware can effectively eradicate such viruses from your computer.

To remove all registry references to a yahoo.xml malware file:

  1. On the Windows Start menu, click Run.
  2. In the Open box, type regedit and click OK. The Registry Editor window opens.
