How to open files from unknown developers without a warning in OSX

anti-viruspasswordSecurity

I believe I have too much security on my mac. Whenever I try changing a file name or install a program I have to enter my laptop's password. Moreover, I cannot quickly access downloaded programs because they are from unidentified developers, and I must right-click > open in order for me to run them. That is really frustrating.
Do I need to my laptop to be THAT secure (due to recent malware attacks on Macbooks ? ) Can I chance the settings to have it a bit more flexible ?

You can disable Gatekeeper in System Preferences:

This removes the warnings about opening files downloaded from the internet:

defaults write com.apple.LaunchServices LSQuarantine -bool false

It doesn't affect the dialogs about opening applications for the first time though.

You can run Finder as root with osascript -e 'quit app "Finder"' && sudo /System/Library/CoreServices/Finder.app/Contents/MacOS/Finder, but it's not really meant to be done permanently.
