It's no secret on the Forums i am on that i use Ubuntu Linux and i have found it secure and have no problems that i have found since changing from windooooows. It's not unusual to have other members have a go when i offer a solution to problems they may have with windooooows.
I wonder what they would say after i read about a computer in China that runs Ubuntu just like i do. OK it's a version in Chinese but the difference being this computer is twice as fast as the last computer that was the fastest computer in the world. After doing a quick search i have just fund that the top 10 fastest computer on the planet all run on Linux. So all these people who criticise me over window then just look at the link below from Wikipedia and the facts.
Of the top 500 the list below shows the operating systems and only windows are used on 2 out of 500 machines.
