I have dabbled in Ubuntu but most people are fixed on Windows-I like the idea of going cold turkey from MS but I feel the learning curve might be to much for some. Kinda like the change from 3.0 to XP. At any rate is there a stand alone Firewall that does what we expect ? Or can we still expect hackers until the end of time ? Will Zorin OS build as a dual boot next to a Windows OS like Ubuntu ?If not does it take a complete HD wipe and fresh install ? Thanks so much for the help as some of the data is either left out or missed on tech talk for the average joe like me.
