Install a Spyware Blocker
One of the best ways to prevent spyware is to install a Spyware Blocker. There are many free and paid Spy Blockers available for download, however if you’re looking for a trusted source consider Microsoft offers Windows Defender for XP onwards.
Prevention is the best cure. By taking the following precautions you can significantly prevent your PC from being infected with Spyware.
Firewalls
A firewall is a type of software that monitors data coming in and out of your computer to stop hackers from accessing your computer. If your computer is infected with Spyware, at some stage it will try to send data home remotely – A firewall with attempt to block this unauthorized transmission and alert the user.
Examine all downloads and installations
Most spyware is installed by downloading software from the internet that has the software hidden within the downloads content. You should deny any request to install software and web browser add-on unless you absolutely need it and it is coming from a trusted software vendor.
When something pops up on your screen you should always take the time to read it – we are accustomed to clicking the ‘OK’ button and often spyware can be install right in front of our eyes. If you are unsure, do a quick search online for the programs name and see what comes up.
It may sound obvious, but websites or peer-to-peer services that offer pirated software, music or movies are havens for spyware and malware.
License Agreements
You should be suspicious of any software that tries to install without prompted the license agreement. If you are worried about private companies recording your PC behaviour, then take time to read the agreement of any software downloaded. You should be extra cautious of free software downloads – they are often the culprit that installs unwanted search tool bars (a way of monetising their “free” software).
Pop-up Blocker
All the major web browsers such as Internet Explorer, Safari, Firefox etc can block web sites from launching pop-up windows. Modern browsers generally have this enabled by default and a warning message will appear at the top of the browser window.
Closing a pop-up window
Cancel doesn’t always mean cancel when it comes to spyware. The creator of the software may try and trick you into installing some unwanted program, so always click the X in the top right of the window in question to close or use the MS Windows keyboard short cut (Alt – F4).
Browser Security Settings
Since Internet Explorer is bundled with Windows it is the most popular browser, making up over 50% market share – therefore most spyware is targeted towards this medium. A simple way to protect yourself is to download Firefox or Google Chrome which are regarded to provide better protection. Older or out-of-date browser also dramatically increase your risk.
If you stick with Internet Explorer, put the security settings for the Internet Zone to medium or higher which restricts the amount of information a website can read and write to on your computer.
Always check for updates
Microsoft is very reactive to spyware and accordingly make many updated available. Windows 7 and Vista both allow you to set updates to download and install automatically – this is highly recommended.
