Choosing the best PC security software can seem very difficult at times. We are doing more information sensitive activities online such as banking and e-mail so keeping your PC secure has never been more important.

There is a massive variety of ways of securing your computer. Information security software can be used to protect the confidentiality of data and many companies offer computer security services. Although services like these may be too expensive and unnecessary for home users and small businesses. In this article we hope to show you the basics of what you need to do to keep your computer secure.

Computer security basics

The security of computers can be breached by malware such as viruses, loggers and other piece of illicit software, collectively known as malware. Several years ago all this software wanted to do was to destroy or interrupt the users experience of the computer.

Nowadays the aim of the game has changed dramatically. Most modern malware wants to detect passwords, usernames and information which can be used to access bank accounts, register services and other crimes using your information and details.

Therefore, you may not be able to tell if you've been infected until you see an erroneous debit on your bank statement. The best PC security software will be able to work in the background to prevent this happening in the first place.

How to choose your PC software


There are now many different types of software including firewalls and scanners which are free. If you have nothing currently installed on your computer then installing one of these will increase your security.

However most the time you do get what you pay for. Paying a one-off or monthly fee may offer you with better updates, additional scanning functions and a more optimised experience. It may also offer additional features such as being able to set a timer for when your software will run.


I'd expect all security software to offer functionality such as virus scanning and firewalls. Additional features may include real-time scanning including scanning sites such as Facebook, searching e-mail software for viruses and spam, and even unrelated features such as accelerating your Internet experience.


I define the effectiveness of a piece of security software, as how well it does its job. For virus scanners this will be what percentages of viruses it will find, and for firewalls the percentage of attacks it repels. There is no easy metric to measure the effectiveness of virus scanners, so search Google for an up-to-date comparison of security software as various sites often pit virus scanners against each other on identically infected computers. This is often the only real way of comparing virus scanners on a like-for-like basis.

You should now be able to choose the best PC security software for your needs. Whether you decide to use specialist tools such as information security software or computer security services to specifically help with your situation may be necessary if you feel the risk is high.
