Threat Details:

  • trojan

Win32.Soundmix copies itself as soundmix.exe into the system directory and pretends to be a soundmixer. It starts itself in autorun as "soundmix" without user consent. It also adds itself to the exefile shell open command so that it will be started synchronously with every other exe file.
Removal Instructions:


Please use Spybot-S&D, RunAlyzer or msconfig.exe to remove the following autorun entries.
  • Entries named "soundmix" and pointing to "<$SYSDIR>\*.exe".


Important: There are more files that cannot be safely described in simple words. Please use Spybot-S&D to remove them.


You can use regedit.exe (included in Windows) to locate and delete these registry entries.
  • Remove "soundmix" from registry value "" at "HKEY_CLASSES_ROOT\exefile\shell\open\command\".
  • Remove "<regexpr>([ \t\n\r\f][ \t\n\r\f]) " from registry value "" at "HKEY_CLASSES_ROOT\exefile\shell\open\command\".
If Win32.Soundmix uses rootkit technologies, use our RegAlyzer, RootAlyzer or our Total Commander anti-rootkit plugins.
