How to remove FUN.XLS

This is another popular article of mine from my previous blog that I brought back. I brought back my some of my previous posts to continuously help computer users recover from a virus attack.

What is FUN.XLS.EXE? This worm gets into your PC through other malwares dropping it. It usually infects removable drives. When this program is executed it drops a copy of itself as ALGSRVS.EXE and MSFUN80.EXE in the Windows system folder. This worm also copies itself as MSIME82.EXE in the Windows folder. This worm drops a copy of itself as FUN.XLS.EXE in all removable drives and It creates a line fo code to the file AUTORUN.INF in the same drives to automatically execute the dropped copies when the drives are accessed.

Follow these steps to remove this virus. Before you perform any cleaning instructions I advised you to first turn off the system restore feature of your operating system for the cleaning to be more effective.

Terminating the Malware Program

This procedure terminates the running malware process.

  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 processes:
    • algsrvs.exe
    • fun.xls.exe
    • msfun80.exe
    • msime82.exe
  3. Select the malware process, then press either the End Task or the End Process button, depending on the version of Windows on your computer.
  4. To check if the malware process has been terminated, close Task Manager, and then open it again.
  5. 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. If the malware process is in the list displayed by either Task Manager or Process Explorer, but you are unable to terminate it, restart your computer in safe mode.
