How Can I Remove the Sasser worm?

Follow these steps in removing the Sasser worm.

1) Disconnect your computer from the local area network or Internet

2) Terminate the running program

* Open the Windows Task Manager by either pressing CTRL+ALT+DEL, selecting the Processes tab or selecting Task Manager and then the process tab on WinNT/2000/XP machines.
* Locate one of the following programs (depending on variation), click on it and End Task or End Process

any process running with the "_up.exe" suffix

* Close Task Manager

3) Activate the Windows XP Firewall (if running Windows XP) or another firewall to prevent the worm from shutting your system down while downloading the patches. To activate the Windows XP firewall, follow these steps.

* Click on Start, Control Panel
* Double-click on Networking and Internet Connections, then click on Network Connnections
* Right-click on the connection you use to access the Internet and choose Properties
* Click on the Advanced Tab and check the box
"Protect my computer and network by limiting or preventing access to this computer from the Internet"
* Click OK and close out of the Network and Control Panel

3) Download and Install the patches for the LSASS Vulnerability and others

* Microsoft Windows NT® Workstation 4.0 Service Pack 6a
* Microsoft Windows NT Server 4.0 Service Pack 6a
* Microsoft Windows NT Server 4.0 Terminal Server Edition Service Pack 6
* Microsoft Windows 2000 Service Pack 2, Microsoft Windows 2000 Service Pack 3, and Microsoft Windows 2000 Service Pack 4
* Microsoft Windows XP and Microsoft Windows XP Service Pack 1
* Microsoft Windows XP 64-Bit Edition Service Pack 1
* Microsoft Windows XP 64-Bit Edition Version 2003
* Microsoft Windows Server™ 2003
* Microsoft Windows Server 2003 64-Bit Edition

5) Remove the Registry entries

* Click on Start, Run, Regedit
* In the left panel go to

HKEY_LOCAL_MACHINE>Software>Microsoft>Windows>Current Version>Run

* In the right panel, right-click and delete the following entry

"skynetave.exe"= "%Windows%\skynetave.exe"

* Close the Registry Editor

6) Delete the infected files (for Windows ME and XP remember to turn off System Restore before searching for and deleting these files to remove infected backed up files as well)

* Click Start, point to Find or Search, and then click Files or Folders.
* Make sure that "Look in" is set to (C:\WINDOWS).
* In the "Named" or "Search for..." box, type, or copy and paste, the file names:

* Click Find Now or Search Now.
* Delete the displayed files.
* Empty the Recycle bin

7) Reboot the computer and update your antivirus software, and run a thorough virus scan using your favorite antivirus program.

For Automatic Removal of Sasser, download the Symantec removal tool, you'll still need to download the patches above and install them, however this removal tool will stop the Sasser worm from running, remove the items in the registry, and delete the infected files.

word of warning, using regedit can cause problems, make sure you understand the instructions and follow them exactly (and maybe verify they are correct on other sites via google).

I really hope this works.
