The short of it, now that I'm totally an Ubuntu guy, I've been studying up on the O.S., lots of on-line reading from (Yahoo) & (Google). I'm very confused on something here, about 70% to 80% of the on-line materials I have seen, say that Linux systems do not require any type of (antivirus) software!?! Then on the flip side of the same coin about 20% to 30% of the material says Linux system operate best with (antivirus) software, and the pro (antivirus) people are saying that AVG is a hot pick for Linux based system!?! So what is it folks? Does Linux require or not require any type of (antivirus) programs? For almost a decade while using Windows 2000 based systems, XP included, I was a total security freak when it came to protecting my Windows O.S., I'm just wanting to know if I have to imply the same "security freak" methods with Linux? "Thanks for your time here folks, I'm just confused"!
