Should I download Malicious Software Removal Tool or is it not necessary with Vista Security Protection?
There is no “Vista Security Protection” product. Even though Vista was designed to be a more secure operating system than XP, you still need an antivirus, firewall (the built-in Vista Firewall is fine for most people), and a non-viral malware scanner (the built-in Windows Defender is fine for most people). The Malicious Software Removal Tool is a limited program that searches for some specific forms of malware. It will not hurt you to run it.
