Software Security – Preventing Malware Attacks

If you plan to do anything online, then you must accept the fact that Malware is not going to go away, and that new forms of malware are simply going to keep surfacing on a regular basis.

The two main ways of dealing with malware are:

  1. Stay informed and up-to-date
  2. Secure your computer against viruses, spyware, and malware.

Staying Up-To-Date

If you are interested in staying up-to-date with the latest malware threats, you can visit threat update pages from reputable security companies like the ones listed below:

Securing Your Computer

Making sure that your computer is free of spyware, malware, and virus infections is vitally important to your online security. There’s no point securing your WordPress site if a keylogger is installed on your computer and can send your password and login details to hackers.

Antispyware / AntiVirus Protection

Anti-spyware programs combat spyware by providing real-time protection, scanning, and removal of any spyware software found on your computer. Antivirus software performs a similar function, but it looks instead for viruses, worms, and trojans, mostly sent to you via email.

Tip: Make sure that any antispyware programs you install on your computer are authentic. Unfortunately, some programs marketed as free spyware detectors will actually install spyware on your computer. It’s best to stick with antispyware software from reputable and trusted manufacturers.

Below are some of the most widely-used and trusted computer protection software programs available to help keep your computer free of malware, spyware, viruses, etc…

Some of the programs listed below are available as a standalone software package, and others are available as part of an integrated security solution. Many security companies offer free or trial versions of their products

We recommend investing in a reliable commercial antispyware/antivirus program for maximum protection against malware and to prevent and eliminate spyware and viruses from infecting your computer system.

Microsoft Security Essentials

Microsoft Windows has a free security program called Microsoft Security Essentials that works in the background to protect your PC. It checks for updates automatically a few times a day and doesn’t slow your PC down while it works …

The program is easy to use and allows you to see if your computer is secure from threats using a very simple system – if the icon next to your computer clock is green, everything’s good; if it’s red, then something is wrong and needs immediate attention …

Clicking on the icon will then open up an alert window notifying you of the problem, and giving you options to fix the issue or potential threat …

Microsoft Security Essentials is available as a free download …

Lavasoft’s Ad-Aware

Ad-Aware is one of the world’s most downloaded security software programs.

Firewall Protection

Firewalls are an important part of your overall online security strategy. A Firewall analyzes traffic data (known as ‘packets’) before it is allowed into your computer and makes sure that it is not malware.

A firewall is like a security guard standing outside a busy nightclub. Its main job is to check everyone coming in while also keeping any undesirables out.

To learn more about using firewalls, see the relevant section in the tutorial below:

Below we have listed a number of software-based firewall programs you may want to look into for protecting your computer from external attacks. Most simple two-way firewalls ask you to allow or deny Internet access to unknown programs. Many automatically allow trustworthy apps and remember your decisions to become silent over time.

Windows Firewall

Microsoft Windows comes with a built-in firewall program. We recommend choosing an alternative firewall solution, however, as these tend to offer easier control of outbound protection and additional features.

If you plan to install a third-party firewall solution, make sure to disable the Microsoft Firewall first, as having two firewalls running simultaneously will create problems.

To do this, click on the ‘Start’ button (the Windows icon located on the bottom left-hand corner of your screen) …

Choose ‘Control Panel’ …

Click on ‘System and Security’ …

Click on ‘Windows Firewall’ (or ‘Check firewall status’) …

From the menu, select ‘Turn Windows Firewall on or off’ …

Here you can turn Windows Firewall on, or off (not recommended unless you are installing a third-party firewall program) …

Note: Some security programs will override your system’s default settings to prevent conflicts from happening. Depending on the security product you have installed, you should see a notification that your security settings are being managed or overridden by the program you have installed …

Norton By Symantec

We covered the Norton security products earlier. As well as antivirus protection, Norton products also provide a Firewall program.

To learn more about Symantec’s range of security products, visit the site below:


Comodo is a robust firewall software solution that consistently scores highly in security tests and security expert reviews.

Comodo includes a “memory firewall” (protects against buffer overflow attacks) and a “sandbox” component that limits unknown applications and new software installations from affecting your computer. If an unknown application attempts to enter your computer via the firewall, Comodo will deny the application and ask you what to do. Comodo’s firewall software application for Windows is available as a free download.

To learn more about Comodo Firewall, visit the site below:


ZoneAlarm is a simple and user-friendly firewall application. ZoneAlarm is currently installed on over 80 million computers and offers advanced firewall protection that monitors programs for suspicious behavior spotting and stopping new attacks that bypass traditional anti-virus protection.

ZoneAlarm offers a free download of the software with certain conditions (e.g. individual and not-for-profit use).

To learn more about ZoneAlarm, visit the site below:


Private Firewall is a feature-packed firewall solution made available as unrestricted freeware. It provides a multi-layer security solution that includes behavior blocking technology, standard firewall protection, virus, spyware, and malware protection, process and application security, registry protection and more.

Additionally, there are many configurable settings, allowing you to set different security levels for Internet access and computer network security (ie. file and printer sharing) and configure different profiles (e.g. Home, Office, and Remote). Private Firewall is a very effective firewall program, but it is aimed primarily at slightly more advanced users.

In addition to the products listed above, we recommend that you search online for user and technology reviews and do your own thorough research and due diligence before investing in a security software program.

As well as enabling firewalls on your computer and other devices in your network, you can also add a firewall to your WordPress site, using plugins.

You can search for WordPress Firewall plugins inside your WordPress dashboard (Plugins > Add New), or the WordPress Free Plugin Directory …

(WordPress Plugins – Firewall)
