Hi there, how can u survive with 500MB of RAM???
I have 2GB n I am crying everyday... (too lazy to go buy more I guess)

Don't worry for security with LW, ur antivirus and FW have already prep it all; however, and when you will decid to open a file downloaded from any P2P, run the said file through ur antivirus.
Go to your LW saved folder, right click on the file, follow instructions.
