Help Severe Trojan Alert! Microsoft Security Essentials detected PWS:Win32/Ldpinch.gen

PortableAapps.com Platform version: 2.0 beta 1
As I had started the PortableApps.com Platform, the Microsoft Security Essentials froze the application and alerted me of a severe trojan. I don't know why but I didn't expect the PortableApps Platform could be performing trojan style commands and be a serious issue?

I hope someone here could help! I have copied and pasted the details of the trojan: PWS:Win32/Ldpinch.gen

Summary
PWS:Win32/Ldpinch.gen is generic detection for PWS:Win32/Ldpinch, a family of password-stealing trojans. This trojan gathers private user data, such as passwords, from the host computer and sends the data to the attacker at a preset e-mail address. The Win32/Ldpinch trojans use their own Simple Mail Transfer Protocol (SMTP) engine or a web-based proxy for sending the e-mail, thus copies of the sent e-mail will not appear in the affected user's e-mail client.
