Just because you use Linux, it doesn't mean your computer doesn't have viruses or worms. Virus is a catch-all phrase, and BitDefender's designed to catch them all - from executable viruses, script viruses, macro viruses, to backdoors, trojans, spyware, adware, diallers, and more.

While there is no excuse for inattention and lack of knowledge, the fact is that there are Linux virus's (viruses, virii?) and there will be more.

The total number of dollars rushing toward cloud computing is massive. The various top research firms - IDC, Gartner, et al. -- all have eyebrow-raising forecasts about the growth rate of cloud-based computing services. But are you seeing a lot of headlines about safety? No, not really, though the worries are out there.

Estimates vary, but generally it is believed that there are 100 to 500 Linux viruses out there. The tiny number of Linux viruses that do exist have never resulted in a significant outbreak. In comparison to the plethora of viruses and worms in Windows-based platforms, the volume of Linux viruses is insignificant. So this leads us to two questions: why are there so few Linux viruses and are Linux anti-virus tools necessary?

It's faster than Windows, it fights viruses – and it's free. Jimmy Lee Shreeve on the software that's bringing more power to our PCs....Linux makes your computer run quicker, it doesn't crash, it doesn't catch anywhere near as many viruses, and it's free. For a decade, it was available only for people to install themselves. But now, the geek's favourite is coming to the masses.

By default, the root account password is locked in Ubuntu - Canonical neither supports nor advocates enabling the root account. This means that you cannot login as root directly or use the su command to become the root user. However, since the root account physically exists it is still possible to run programs with root-level privileges.

These days, everybody is talking about cloud computing, and many people use it in one form or the other. But popular cloud computing services are provided by a third party, which means that you store you data on a server somewhere, so that you can access it any time, from anywhere. But there are cloud applications that any person can use to host their own private cloud, from their home.

With the lay public now moving their businesses and lives online, everything they do has an electronic component. But, being lay people, they’re using the most antiquated, bug-ridden, security-deficient, poorly-implemented solutions and services possible.

Now comes a new rallying cry: software wants to be free. Or, as the tech insiders say, it wants to be “zero dollar.”

A growing number of consumers are paying just that — nothing. This is the Internet’s latest phase: people using freely distributed applications, from e-mail and word processing programs to spreadsheets, games and financial management tools. They run on distant, massive and shared data centers, and users of the services pay with their attention to ads, not cash.

While such services have been emerging for years, their rapid adoption has been an important but largely overlooked driver of the $44.6 billion hostile bid that Microsoft made to take over Yahoo this week.
