Manual Removal Instructions
To remove this virus "by hand", follow these steps:
Apply the MS03-039 patch (includes MS03-026 patch)
Terminate the process msblast.exe
Delete the msblast.exe file from your WINDOWS SYSTEM32 directory (typically c:\windows\system32 or c:\winnt\system32)
Edit the registry
Delete the "windows auto update" value from
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\
Windows\CurrentVersion\Run
Here's the patch download page.
Right-click on the takbar to get into taskmanager, and highlight the msblast.exe process, and terminate it.
When you search for the msblast.exe file to delete it, also search for teekids.exe and penis32.exe and also delete them if present. You have to end the task beforehand (as stated above), or it will not allow you to delete it.
To edit the registry, select 'Run' from your start menu. Type REGEDIT in the box. Or, you can go to the command (c:\) prompt, and trype regedit from there.
When you find the "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\
Windows\CurrentVersion\Run" branch of the tree in the left pane, the "windows auto update" should appear in the right-hand pane. Highlight it, right-click on it, and select 'delete'
Reboot.
You will have to dowload the patch from another machine that is clean, but it's small enough to fit a floppy.
