Top preferred antivirus for Android Phones.

The subject of security for the Android platform is far from straightforward. There’s some debate about whether you really need antivirus apps on your smartphone. Much depends on whether you sideload apps, but there’s no denying that malware has grown into a much greater concern since we first wrote this article back in 2012. Luckily, security apps have improved dramatically to keep pace with the new threats, so you have plenty of great protection to choose from.

The majority of Android security apps are actually packages that include a host of other tools from contact filtering to remote lock or wipe. We decided to take a look at the top five Android security apps and find out what they do. We are taking a look at these from a consumer point of view, so be warned that some of the “free” apps are only free for personal, non-commercial use.

• 360 Security (Free)

A major player in China, developer Qihu burst onto the scene and claimed the top spot in AV-Test’s September 2013 report with a virtually flawless detection rate of 99.9 percent, the highest of any of the security apps tested. In the latest November 2015 report, it achieved a detection rate of 99.9 percent. The focus with 360 Mobile Security is firmly on detecting and nullifying threats to your system. It has a very streamlined, elegant design. It’s extremely lightweight, and it’s completely free. A standard real-time scan will safeguard your device from malware, spyware, and the threat of infection. It’s also capable of detecting and fixing system vulnerabilities and cleaning up idle background apps to help your phone run more efficiently. There’s a privacy advisor and a tool to clear your usage history.

The latest version of 360 Security boasts a lot of extras, including a junk file cleaner, memory booster to free RAM, a power saving option, app management, privacy with encryption, and anti-theft tools for locating or remotely wiping your phone. For a good blend of usability and strong protection, you should think about 360 Security. It offers smooth performance and a host of extra features, so it is bound to appeal to many users.

• Avast! Mobile Security 

As a genuinely free app for the Android platform, Avast! Mobile Security is offering an impressive range of tools. It has antivirus protection, it scans your apps to provide details on what they are doing, and it has a Web shield that scans URLs for malware.

There are various additional tools in the package and the best of the bunch is the anti-theft component. The app is actually based on an old app called Theft Aware which Avast acquired. The anti-theft feature is hidden and allows you to remote control your smartphone using SMS. So if you lose your phone, you can remotely lock it, locate it, or wipe it. You can make it play a siren sound, lock down the SIM card, and prevent USB debugging as well. It’s a comprehensive solution for theft protection.

If you have a rooted device then there’s also a firewall that allows you to control network traffic. You can block access to Wi-Fi or the network for specific apps which is handy for security and potentially saving on battery juice as well.

According to the latest AV-Test report of 25 popular Android security apps, Avast is a solid option with an overall detection rate of 98.1 percent. Although it is not top of the charts in terms of malware detection, the extra functionality (including the anti-theft tools and a firewall for rooted devices) still make it worth considering. It has a light footprint with no discernible drain on battery life and no impact on general performance. It also returned no false positives.

The fact this app is completely free, has a wide range of features, and offers protection for rooted devices, makes it a strong contender. If you’re looking for a security solution for your Android smartphone, and your primary concern is malware and safe browsing, then this could be the right app for you.

Avast Marketing Director, Milos Korenko, has assured us that “There might be a paid version in the future but that won’t have an impact on the free version. It will continue to be available and loaded with features.”

• ESET Mobile Security & Antivirus

Eset deserves its place in our top five with a 100 percent detection rate in the latest AV-Test report and an easy-to-use interface. The basic app is completely free and it provides real-time scans of apps to detect malware and potentially dodgy apps trying to send texts or make premium rate calls.

The free version also includes a suite of anti-theft tools. You can remotely locate and lock your smartphone or tablet, and you can prevent anyone from uninstalling apps by using password protection.

If you want remote wipe or SIM guard capabilities then you have to spring for the premium version at $20 per year, but it also delivers anti-phishing protection, an app audit feature, device monitoring for unwarranted use of data, and advanced call blocking.

• Avira Antivirus Security 

With a 99.9 percent detection rate and no false positives, you can trust the free version of Avira to keep your Android smartphone or tablet safe. It has a light footprint in terms of performance and a sleek, minimalist design that fits in well with the Android platform.

Avira allows you to scan apps for potential trouble and it scans new apps or updates automatically. There’s also the usual batch of anti-theft tools, to help you find your device remotely, lock it, wipe it, or trigger an alarm.

There’s also an identity safeguard tool that can tell you whether your email account, or the email addresses of your friends, have been leaked or compromised. A decent range of blacklisting options rounds off this app, so you can block problem callers or nuisance spam.

There is a premium version that adds anti-phishing, more regular updates, and better support, but the free version covers enough bases for most people.

• AVL

Some of you are probably just looking for malware protection that’s as barebones as possible. If you don’t want anti-theft tools, or identity protection, or any of the other possibly superfluous features that come in many security apps then AVL will suit you.

This app scored a 99.8 percent detection rate with one false positive and AV-Test found performance was good with no undue impact on speed or battery life. AVL can scan a variety of file formats beyond APKs and it’s designed to be fast and efficient. It does also offer call blocking capabilities.

AVL - Android Apps on Google Play

Other options

The last time we checked 18 of the 31 apps tested by AV-Test in March 2014 scored 100 percent detection rates, a feat that only 4 out of the 25 apps tested between July and December 2015 managed. If you don’t fancy any of our picks then Sophos Free Antivirus and Security and Trend Micro Mobile Security & Antivirus offer free versions that are worth a look. Both scored a 100 percent detection rate and could easily have made the list.

From the big name security software brands, Kaspersky and Norton will attract many people because they are familiar names, but compared to some of the free options there’s really nothing there to justify the price tags. Same goes for the excellent Bitdefender Mobile Security & Antivirus. Bitdefender and Norton did score 100 percent in November’s test, but they are only free trials and will bug you about paying out an annual subscription.

And the winner is…

You can read about whether you actually need antivirus protection and run through some common sense ways to safeguard your Android device in the next two parts of this security series. However, if you do want to go ahead and get an Android security app, 360 Mobile Security is your best bet right now. It offers the functionality you’d expect from a premium app for free. If you’re not sure about 360 Mobile Security then we’d recommend ESET Mobile Security & Antivirus.

If you’ve tried any of these apps out or you have another Android security app you feel is worthy of a mention then post a comment and let us know about it.

SECURITY IN LINUX OPERATING SYSTEM

Five key factors underline Linux's superior security:

1. Privileges

Linux systems are by no means infallible, but one of their key advantages lies in the way account privileges are assigned. In Windows, users are generally given administrator access by default, which means they pretty much have access to everything on the system, even its most crucial parts. So, then, do viruses. It's like giving terrorists high-level government positions.

With Linux, on the other hand, users do not usually have such "root" privileges; rather, they're typically given lower-level accounts. What that means is that even if a Linux system is compromised, the virus won't have the root access it would need to do damage systemwide; more likely, just the user's local files and programs would be affected. That can make the difference between a minor annoyance and a major catastrophe in any business setting.

2. Social Engineering

Viruses and worms often spread by convincing computer users to do something they shouldn't, like open attachments that carry viruses and worms. This is called social engineering, and it's all too easy on Windows systems. Just send out an e-mail with a malicious attachment and a subject line like, "Check out these adorable puppies!"--or the porn equivalent--and some proportion of users is bound to click without thinking. The result? An open door for the attached malware, with potentially disastrous consequences organizationwide.

Thanks to the fact that most Linux users don't have root access, however, it's much harder to accomplish any real damage on a Linux system by getting them to do something foolish. Before any real damage could occur, a Linux user would have to read the e-mail, save the attachment, give it executable permissions and then run the executable. Not very likely, in other words.

3. The Monoculture Effect

However you want to argue the exact numbers, there's no doubt that Microsoft Windows still dominates most of the computing world. In the realm of e-mail, so too do Outlook and Outlook Express. And therein lies a problem: It's essentially a monoculture, which is no better in technology than it is in the natural world. Just as genetic diversity is a good thing in the natural world because it minimizes the deleterious effects of a deadly virus, so a diversity of computing environments helps protect users.

Fortunately, a diversity of environments is yet another benefit that Linux offers. There's Ubuntu, there's Debian, there's Gentoo, and there are many other distributions. There are also many shells, many packaging systems, and many mail clients; Linux even runs on many architectures beyond just Intel. So, whereas a virus can be targeted squarely at Windows users, since they all use pretty much the same technology, reaching more than a small faction of Linux users is much more difficult. Who wouldn't want to give their company that extra layer of assurance?

4. Audience Size

Hand-in-hand with this monoculture effect comes the not particularly surprising fact that the majority of viruses target Windows, and the desktops in your organization are no exception. Millions of people all using the same software make an attractive target for malicious attacks.

5. How Many Eyeballs

"Linus' Law"--named for Linus Torvalds, the creator of Linux--holds that, "given enough eyeballs, all bugs are shallow." What that means is that the larger the group of developers and testers working on a set of code, the more likely any flaws will be caught and fixed quickly. This, in other words, is essentially the polar opposite of the "security through obscurity" argument.

How Operating Systems Work

Within the broad family of operating systems, there are generally four types, categorized based on the types of computers they control and the sort of applications they support. The categories are:

Real-time operating system(RTOS)

Real-time operating systems are used to control machinery, scientific instruments and industrial systems. An RTOS typically has very little user-interface capability, and no end-user utilities, since the system will be a "sealed box" when delivered for use. A very important part of an RTOS is managing the resources of the computer so that a particular operation executes in precisely the same amount of time, every time it occurs. In a complex machine, having a part move more quickly just because system resources are available may be just as catastrophic as having it not move at all because the system is busy.

Single-user, single task

As the name implies, this operating system is designed to manage the computer so that one user can effectively do one thing at a time. The Palm OS for Palm handheld computers is a good example of a modern single-user, single-task operating system.

Single-user, multi-tasking

This is the type of operating system most people use on their desktop and laptop computers today. Microsoft's Windows and Apple's MacOS platforms are both examples of operating systems that will let a single user have several programs in operation at the same time. For example, it's entirely possible for a Windows user to be writing a note in a word processor while downloading a file from the Internet while printing the text of an e-mail message.

Multi-user

A multi-user operating system allows many different users to take advantage of the computer's resources simultaneously. The operating system must make sure that the requirements of the various users are balanced, and that each of the programs they are using has sufficient and separate resources so that a problem with one user doesn't affect the entire community of users. Unix, VMS and mainframe operating systems, such as MVS, are examples of multi-user operating systems.

It's important to differentiate between multi-user operating systems and single-user operating systems that support networking. Windows 2000 and Novell Netware can each support hundreds or thousands of networked users, but the operating systems themselves aren't true multi-user operating systems. Thesystem administrator is the only "user" for Windows 2000 or Netware. The network support and all of the remote user logins the network enables are, in the overall plan of the operating system, a program being run by the administrative user.

With the different types of operating systems in mind, it's time to look at the basic functions provided by an operating system.

Top programming languages you should know to be master in computer world.......

Knowing a handful of programming languages is seen by many as a harbor in a job market storm, solid skills that will be marketable as long as the languages are. Yet, there is beauty in numbers. While there may be developers who have had riches heaped on them by knowing the right programming language at the right time in the right place, most longtime coders will tell you that periodically learning a new language is an essential part of being a good and successful Web developer.

1. PHP
What it is: An open-source, interpretive, server-side, cross-platform, HTML scripting language, especially well-suited for Web development as it can be embedded into HTML pages.
Why you should learn it: Its particularly widely used. "High-speed scripting with caching, augmented with compiled code plug-ins (such as can be done with Perl and PHP) is where the future is. Building Web apps from scratch using C or COBOL is going the way of the dinosaur," said Duquaine.
Job availabilities: 1,152*

2. C#

What it is: A general-purpose, compiled, object-oriented programming language developed by Microsoft as part of its .NET initiative, it evolved from C and C++
Why you should learn it: Its an essential part of the .Net framework. "Learning C#, which is just Java with a different name plate, is critical if you heavily use Microsoft," said Duquaine.
Job availabilities: 5,111

3. AJAX (Asynchronous JavaScript and XML)
What it is: Though technically not a programming language, AJAX uses XHTML or HTML, JavaScript and XML to create interactive Web applications.
Why you should learn it: Ever since Google Maps put AJAX, well, on the map, the requests for AJAX-knowledgeable pros went through the roof. "The demand for AJAX knowledge is huge because its so damned hard to learn," said Huckaby. Of note, Microsoft announced recently plans to release a tool named Atlas that will make AJAX easier to implement. "If Microsofts Atlas tool is successful, it would bring the extreme complexity and annoyance of AJAX to the average worker," said Huckaby.
Job availabilities : 1,106

4. JavaScript
What it is: Not to be confused with Java, JavaScript is a an object-oriented, scripting programming language that runs in the Web browser on the client side. Its smaller than Java, with a simplified set of commands, easier to code and doesnt have to be compiled.
Why you should learn it: Embedded into HTML, its used in millions of Web pages to validate forms, create cookies, detect browsers and improve the design. With its simplicity to learn as well as wide use, its considered a great bang for your educational buck.
Job availabilities: 4,406

5. Perl
What it is: Perl is an open-source, cross-platform, server-side interpretive programming language used extensively to process text through CGI programs.
Why you should learn it: Perls power in processing of piles of text has made it very popular and widely used to write Web server programs for a range of tasks. "Learning some form of scripting language, such as Perl or PHP is critical if you are doing Web apps," said Duquaine.
Job availabilities: 4,810

6. C
What it is: A standardized, general-purpose programming language, its one of the most pervasive languages and the basis for several others (such as C++).
Why you should learn it: "Learning C is crucial. Once you learn C, making the jump to Java or C# is fairly easy, because a lot of the syntax is common. Also, a lot of C syntax is used in scripting languages," said Duquaine.
Job availabilities: 6,164, including all derivatives

7. Ruby and Ruby on Rails
What they are: Ruby is a dynamic, object-oriented, open-source programming language; Ruby on Rails is an open-source Web application framework written in Ruby that closely follows the MVC (Model-View-Controller) architecture.
Why you should learn it: With a focus on simplicity, productivity and letting the computers do the work, in a few years, its usage has spread quickly. As a bonus, many find it easy to learn.
Job availabilities : 210 and 54, respectively

8. Java
What it is: An object-oriented programming language developed by James Gosling and colleagues at Sun Microsystems in the early 1990s.
Why you should learn it: Hailed by many developers as a "beautiful" language, it is central to the non-.Net programming experience. "Learning Java is critical if you are non-Microsoft," said Duquaine.
Job availabilities: 14,408

9. Python
What it is: An interpreted, dynamically object-oriented, open-source programming language that utilizes automatic memory management.
Why you should learn it: Designed to be a highly readable, minimalist language, many say it has a sense of humor (spam and eggs, rather than foo and bar), Python is used extensively by Google as well as in academia because of its syntactic simplicity.
Job availabilities: 811
