Microsoft is maker of well known operating systems and it has many best selling units of OS modules in the market. The experts always argued that MS is not the company for masses. Its operating systems are buggy and are unstable. While Unix has proved its worth and some of the derivatives do not cost anything except installation cost. During recent surveys and trade shows, many experts argued over the validity of anti-virus market. It is surprising to see that Microsoft knows well that its OS is vulnerable to virus attacks and despite the well known facts, Microsoft chooses to turn blind eye, Its operating system comes without any warrantee or committed features. You have to spend money to secure OS and there are anti-virus makers who are earning great sales volumes just because OS makers do not want to fulfill the obligations of securing their own software. Software for masses must be secure and should not cost much money. There are many nations which can not spend money on software and hardware licenses. Many non-profit organizations also need the solutions which are cheaper. There is no interest from commercial ventures so far.
