When Adware.Sheldor is executed, it does the following:
- Displays the error message:
"E47250: Incorrect MPEG Data format"
- Copies itself as %System%\Shellexpl.exe or %System%\shellexp.exe
Note: %System% is a variable. The Trojan locates the System folder and copies itself to that location. By default, this is C:\Windows\System (Windows 95/98/Me), C:\Winnt\System32 (Windows NT/2000), or C:\Windows\System32 (Windows XP).
- Adds one of the following values:
"Explorer"="%System%\Shellexpl.exe"
"Explorer"="%System%\shellexp.exe en.."
to one of the following registry keys:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
so that the Adware runs when Windows starts.
- Creates one or more of the following configuration files:
- %System%\Hndldt.ini
- %System%\Winhndl.ini
- %System%\windll.ini
- Modifies the Hosts file (located at %SYSTEM%\drivers\etc\hosts in Windows XP and 2K and %Windir%\hosts in Windows 98/ME) by adding the line:
64.237.37.47 auto.search.msn.com
which redirects searches to Adware.Sheldor's search site.
Note: %Windir% is a variable that refers to the Windows installation folder. By default, this is C:\Windows or C:\Winnt.
