I initially was intrigued by Linux/Ubuntu because I thought it was totally impervious to viruses and malware .... silly me. I haven't had a problem with either since installing Ubuntu. But I've only had Ubuntu on my machine for about 3 days.
The question comes to 'Screenlock.' I currently have it set up that when my Screensaver comes on Screenlock activates. When Screenlock activates does that stop anything coming through the internet connection? Is it like if someone would try to break into my computer from the Internet would my computer act like a proverbial or should that be 'virtual' brick wall?
Have a Great Day,
