A technique that spyware, adwares, viruses, keyloggers etc use to go undetected is to drop files that have almost the same name as a legitimate file. WinDir.sachost is a warning that there is a file named sachost.exe located in %WinDir% on your system. The legitimate svchost.exe file is located in %SystemDir%. You might want to analyse %WinDir%\sachost.exe to verify it is something that you really want on your system. Do not delete %WinDir%\sachost.exe unless you are 100% sure it is a threats.

Note: %WinDir% is a variable (?). By default, this is C:\Windows (Windows 95/98/Me/XP) or C:\WINNT (Windows NT/2000).
Note: %SystemDir% is a variable (?). By default, this is C:\Windows\System (Windows 95/98/Me), C:\WINNT\System32 (Windows NT/2000), or C:\Windows\System32 (Windows XP).



If you have any of the files related to WinDir.sachost on your system, please send them for additional analysis. Generally, I have only analysed a few versions for each software component listed at this web site. With your help I will be able to look at both old and more recent versions of the WinDir.sachost software. Thank you very much for your time!
