This signature detects Taidoor Trojan activity on the infected machine.
The Trojan injects itself into services.exe if a %ProgramFiles%\Mcafee folder exists. Otherwise, it injects itself into the svchost.exe process.
The Trojan then opens a backdoor on the infected machine.
Complete system scan is recommended.
