COM surrogate error

If you are using a Microsoft Windows x64 operating system (Windows 7 or Windows Server 2008 R2), along with Kaspersky security software (Kaspersky Anti-Virus 2011or Kaspersky Internet Security 2011), you have probably faced an issue with Windows Picture Viewer, at which you experience unresponsive Windows while opening image files, having Kaspersky software running (KAV 2011 or KIS 2011).

In order to permanently fix this issue, if you use KAV 2011, go to “Settings > Detected Threats and Exclusion Rules“, click “Settings” (under Exclusions) and add dllhost.exe in the Trusted Applications, which is located both in “C:\Windows\System32\dllhost.exe” and “C:\Windows\SysWOW64\dllhost.exe“.
