More Information
Troj/StartPa-MN is a Trojan which modifies the Internet Explorer Start-Page and changes the Search options.
When run the Trojan creates two helper files system32.exe and mspxs32.dll in the Windows system folder and runs system32.exe. The following registry entries are created so that the Trojan may auto-start on user logon or computer restart:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run
Win32 Explorer = %SYSTEM%\explorer32.exe
HKCU\Software\Microsoft\Windows\CurrentVersion\Run
Win32 Explorer = %SYSTEM%\explorer32.exe
Troj/StartPa-MN also lowers the Internet Explorer security settings allowing running of scripts and downloading of files.
