Hello, webmaster.

I received it with my morning mail but it seems to me everything is yours.
Look and tell to delete it or don’t.

This version of malware itself doesn’t do much harm when looking to the activity. It will create a new file%Temp%\svchost [file and pathname of the sample #1], create a new service svchost.exe, add one Windows registry.
