Comparison of Free Vs Paid Internet Security Top 10 Free and Paid Products

First it is useful to point out who is choosing free software vs. paid programs. When new computers are sold, they are typically pre-loaded with at least one full featured security suite - available as a free trial for a month or two. This recommended paid product is optional and is made available for those who are new to computers, and may not be aware that alternatives exist, or where to go to find them - knowing that most who default into this category will opt to follow recommendations and stay with, and pay for the program.

On the other hand, if youve been around the block a few times, you have by now enough savvy to know that anyone will try to sell you anything. Youre likely aware of other options and programs available to achieve the same results - whether self taught, by word of mouth, or doing your own web research. Regardless, you still end up wondering how exactly can free internet security compare or compete with the paid versions?

Contents: Whats the difference?

Paid internet security suites are designed for optimal performance and dependability. They include all the components that make up a comprehensive package for maximum computer protection - and feature live, accessible customer service. These components are a combination of - anti-virus, anti-spyware, ad ware, anti-malware, a firewall, anti-phishing detection, and recently, some form of live, real-time protection - detecting any malware activity - which may already be in progress - by continuous scanning for anything out of the ordinary. Protection like this is found in the full-featured, all-in-one, or premium security suites.

Free versions are individual components used in combination with other free components to custom build a comprehensive security defense. The idea is that combining individual free programs - achieves the same level of protection found in the paid versions. For example, I may start with a free anti-virus, then add a free anti spyware, adware, and malware program, then consider a firewall, and some sort of real-time protection to expose suspicious activity unidentified by all the others. These components together essentially resemble what you will find in an all-in-one security suite. Though I may not have access to customer support, how often really will I need to contact them? Maybe only if their service is unavailable for some reason, which usually means its on their end anyway - and will soon be resolved.

Performance: Is one more effective than another?

The answer is - not by much. Ive reviewed various results published by reliable sources. The trend seems to favor the paid products, but only by about 1% to 10% average, regarding performance and dependability. Ive put together a list consisting of the most highly rated free and paid internet security software offers. According to most resources available, these 2 groups reflect the most commonly agreed upon results. They are not in any particular order - as they seem to vary slightly from year to year. The fact that they are or have been consistently highly rated, and remain in the top 10, supports their reputation. Keep in mind that most free versions of internet security, also offer paid upgrades as well - usually named something like Pro, or Premium. You can search and compare them on your own if interested in knowing more about specific features or details for each.

Free Internet Security:

1. Avast.com - Antivirus
2. Avira.com or Antivir
3. AVG.com Antivirus
4. ZoneAlarm Firewall - Checkpoint.com (formerly Zonelabs)
5. Adaware - Lavasoft.com
6. Microsoft Security Essentials - microsoft.com/security_essentials
7. Comodo.com
8. Threatfire.com - (compliments most other components with real-time protection)
9. PandaSecurity.com - Panda Cloud
10. SUPERAntiSpyware.com - Super Antivirus

Paid Internet Security Suites:

1. Symantec.com - Norton Antivirus
2. McAfee.com
3. Avast.com - Premium
4. Kaspersky.com - Kaspersky Lab Internet Security
5. Gdatasoftware.com - G-Data.
6. Bitdefender.com
7. PCTools.com - Internet Security
8. F-Secure.com
9. Webroot.com - Webroot Internet Security Essentials
10.Trendmicro.com - Trend Micro

There are very good reasons supporting both decisions:

The consensus seems to validate that free versions are as reliable as the paid ones. People who tend to know more about internet security and are more computer/internet savvy in general will recommend the free products hands down. But their preferences are based on knowledge that many of us neither have, nor are even interested in - which is a solid argument for: go ahead and pay - they know more than I do. So it really comes down to what kind of operator are you? Do you have work to do and dont mind paying for reliable protection and piece of mind? Or are you more inclined to decide for yourself which components to include in your customized defense? There will always be choices - free alternatives to just about anything you can install on your computer.

If you are an interviewer -- it really pays to ask well rounded questions to judge the real experience of the candidate as opposed to just relying on the number of years. If you are an interviewee -- You have no control over what questions will be asked in Java job interviews, but there are a few Java interview questions that are very frequently asked in job interviews, and it really pays to prepare for those questions. Here are a few such questions. This is based on some of my recent interviews. Brushing up on these answers will boost your success rate in Java job interviews.

The focus is on judging your experience. So, go through your resume and reflect back on your hands-on experience. Many of these answers will also serve you well in selling your technical strengths to open ended questions like -- tell me about yourself? , why do you like software development?, when reviewing others work, what do you look for?, what was your most significant accomplishment?, etc

Q1. Can you describe the high level architecture of the application that you had worked on recently? or Can you give a 100 feet birds eye view of the application you were involved in as a developer or designer?

A1. The purpose is to judge your overall experience. Here are a few links that will prepare for this most sought-after question, especially for the experienced professionals.

• 3 to n-tier enterprise Java architecture, the MVC-2 design pattern, the distinction between physical and logical tiers, and the layered architecture.The logical tiers shown in the diagrams for the above link are basically layers, and the layers are used for organizing your code. Typical layers include Presentation, Business and Data – the same as the traditional 3-tier model. But when  talk about layers, we’re only talking about logical organization of code. Physical tiers however, are only about where the code gets deployed and run as war, ear or jar. Specifically, tiers are places where layers are deployed and where layers run. In other words, tiers are the physical deployment of layers.
• high level architectural patterns and the pros and cons of each approach. Discusses a number different architectual styles like MVC, SOA, UI Component, RESTful data composition, HTML data composition, Plug-in architecture, and Event Driven Architecture (EDA). Also, covers a sample enterprise architecture, which is a hybrid of a number of architectural styles.
• knowing the difference between a component and a service. Covers the differences between components and services and CBA (Component Based Architecture) Vs, SOA (Service Oriented Architecture). Also, briefly covers single page web design and SCA (Service Component Architecture)
• Understanding of various types of application integration styles. Enterprise applications need to be integrated with other systems, and this post covers different integration styles like sharing the same database, feed based, RPC style (e.g. web services), and exchanging JMS messages.
• Good working knowledge of popular and sought-after technologies and frameworks like Maven, Spring, Hibernate, JSF, etc. Covers a number of tutorials using sought-after frameworks and technologies like like Spring, Maven, JSF, JDBC, and RESTful web service.

A4. 

• Know the SDLC and the best practices . Gives a high level overview of SDLC.

Q5: Can you write code? How would you go about implementing .....?
A5:  You will be asked to write a small function or a program. The interviewer will be looking for things like

• How well you analyze the requirements and the solution? Ask relevant questions if the requirements are not clear. Think out loud so that the interviewer knows that how you are approaching the problem.The approach is more important that arriving at the correct solution.
• List all possible alternatives.
• Write pseudo code.
• Write unit tests.
• Where required, brainstorm with the interviewer.
• Find ways to improve your initial solution. Talk through thread safety and best practices where applicable.

Here are some links to popular coding questions and answers.

• Java coding interview questions and answers:. Covers a number of coding questions with answers. These are some of the popular coding interview questions like reversing a string, calculating the Fibonacci number, recursion vs iteration, equals versus ==, etc.

Q6. How would you go about designing a car parking station?
A6.
Map out the requirements:

• The car park needs to cater for different types of car parks like regular, handicapped, and compact.
• It should keep track of empty and filled spaces.
• It should also cater for valet parking.

Map out the classes that would be required. Use a UML class diagram. Here are some points to get started.

• A CarPark class to represent a parking station.
• A ParkingSpace can be an abstract class or an interface to represent a parking space, and RegularParkingSpace, HandicappedParkingSpace, CompactParkingSpace, etc are subtypes of a ParkingSpace. This means a RegularParkingSpace is a ParkingSpace.
• A CarPark has a (i.e. composition) finite number of ParkingSpaces. A CarPark also keeps track of all the parking spaces and a separate list of all the vacant parking spaces.
• A Vehicle class uses a (i.e. delegation) ParkingSpace.  The Vehicle class will hold attributes using enum classes like  VehicleType and ParkingType. The vehicle types could be Compact, Regular, and Handicapped. The parking types could be Self or Valet. Depending on the requirements, the self or valet types could be designed as subtypes of the Vehicle class.

Q7: Can you design the classes that represent a restaurant?
A7: Very popular. Good understanding of OO design is vital to job interview success. Learn the SOLID design principles, know why you favor composition over inheritance, and dont under estimate the power of coding to interface.

• Java OO Interview Questions and Answers. A step-by-step tutorial explaining how you would go about designing your classes. The "Core Java Career Essentials" PDF covers more examples on SOLID design principles with working code.

How would you go about identifying thread safety issues in an application? How would you go about identifying memory leaks issues? How would you go about identifying performance issues?, etc to judge your experience. I am yet to work on a project that didnt face problems relating to thread safety, memory leaks, and performance issues. Hence, it really pays to market your skills and experience in fixing issues relating to these common challenges.


Q8. How will you go about fixing memory leaks in Java?
A8. Again, a very common problem, and a thorough answer will go a long way in securing your next Java job.

• Detecting and fixing memory leak issues in Java. Tools and techniques to detect memory leaks in Java.
• Memory profiling in Java. Tutorial on memory profiling a Java application.

Q9: How will you go about fixing performance issues in Java?
A9:

• Detecting performance issues in Java. A basic tutorial covering -- how to detect performance issues.
• Also, refer to the JMeter tutorials in this blog as to learn how you can put load on your application to simulate concurrent users.

Q10: How will you go about detecting and fixing thread-safety issues in Java?
A10: Debugging concurrency issues and fixing any thread starvation, dead lock, and contention requires skills and experience to identify and reproduce these hard to resolve issues. Here are some techniques to detect concurrency issues.

• Manually reviewing the code for any obvious thread-safety issues. There are static analysis tools like Sonar, ThreadCheck, etc for catching concurrency bugs at compile-time by analyzing their byte code.

• List all possible causes and add extensive log statements and write test cases to prove or disprove your theories.

• Thread dumps are very useful for diagnosing synchronization problems such as deadlocks. The trick is to take 5 or 6 sets of thread dumps at an interval of 5 seconds between each to have a log file that has 25 to 30 seconds worth of runtime action. For thread dumps, use kill -3 in Unix and CTRL+BREAK in Windows. There are tools like Thread Dump Analyzer (TDA), Samurai, etc. to derive useful information from the thread dumps to find where the problem is. For example, Samurai colors idle threads in grey, blocked threads in red, and running threads in green. You must pay more attention to those red threads.

• There are tools like JDB (i.e. Java DeBugger) where a “watch” can be set up on the suspected variable. When ever the application is modifying that variable, a thread dump will be printed.

• There are dynamic analysis tools like jstack and JConsole, which is a JMX compliant GUI tool to get a thread dump on the fly. The JConsole GUI tool does have handy features like “detect deadlock” button to perform deadlock detection operations and ability to inspect the threads and objects in error states. Similar tools are available for other languages as well.
