Why is Linux/Ubuntu less prone to Malware/Viruses?

- Programs are run as normal user, not Root User.
- Vast diversity makes it difficult to reproduce flaws in a system.
- All software and drivers are frequently updated by Package Managers.

Why is GNU/Linux not as popular as Windows though it has so many advantages and benefits
It is known that technology particularly software has an element of addiction and people are unwilling to move to a 'new' environment requiring learning (also Newtons first law :-) ). this also adds to the 'lock-in' of the software. in an environment where proprietary software is pirated, it is already free (mufta) so no immediate economic benefit is seen in adopting public software.
The challenge is to explain to people that this is not about mufta but about mukta - that the learning resources we use (software is a digital tlm) must be publicly owned so that we all have the freedom to share and modify. If a private company owns them then our learning process is under the control of the vendor who can decide the access to the software. Hence this is a philosophical and ethical issue (rather than purely technological or economic) and like any other social change process (like fighting alcoholism for eg - the benefits of avoiding alcohol is known still it is not easy to give it up), change will be slow and gradual.
Also there are strong forces to keep us chained to proprietary software - hardware vendors who get commission on sale of the proprietary software (no commission on public software!!), proprietary software vendors who adopt unethical and illegal practices to push their products. and the willingness of many of us to stay ignorant :-) and avoid this debate/discussion on the ethics of using proprietary software on grounds of "convenience"
Gnu/linux is public software, intended for public use in all areas (not just education). it is our collective responsibility (all of us in society need to come together to insist that we will only use digital resources that are not proprietary), proprietising (privatising) digital resources and preventing their free sharing (which is so simple - copy/paste) is unethical and greatly harmful to society.
But there are many positive examples - in many countries (and states in India like Kerala), once many people start using GNU/Linux, it spreads fast. Specially if teachers use it, they can explain the benefits to students. So let us keep talking about the importance of software freedom, of the need for public software (like public education) for universal access... and supporting people to adopt it.. our efforts will surely give the result--
