Useful Information


Malware is a general title for all the different types of malicious programs that can inveigle their way into your computer. They are usually installed on your computer without your knowledge, and can cause a wide range of problems for you and your computer. The symptoms that you observe may range from slow performance to computer malfunction, (crashes, loss of data) to compromising of security, and even to complete loss of all data on your computer. The names for the main different types of malware are as follows:

Viruses, Worms, Wabbits, Trojans, Spyware, Backdoors, Exploits, Rootkits, Keyloggers, Diallers, URL injectors, Adware.

Here is a link to a summary of each of these types of malware.

Spyware and Adware

What are spyware & adware?

Spyware is similar to a computer virus, but it remains concealed on your PC and tracks your mouse clicks, text entries, website visits and so on. It can slow down your broadband connection, and, more importantly, can redirect anything you type (for example your credit card number) to somebody else who could use these details fraudulently.

Adware can also reside on your PC without your knowledge, causing unwanted advertising pop-ups, changing your default homepage, inserting strange icons onto your desktop or into your favourites, or resetting your chosen search engine.

How to get rid of spyware?

Prevention is better than a cure, especially as some of the worst types of spy- and ad-ware are very difficult, time consuming, and potentially costly to remove. Install anti-virus and anti-spyware software, a firewall, and keep your computer up to date with Microsoft Update.

If you think your PC is affected by this type of software, some anti-virus scanners can identify and delete some instances of this type of annoyance. There are also several free programs available which can scan your PC for spyware and remove it, for example at

We recommend the following free programs for spyware and adware detection, removal and protection:

Ad-Aware 2007 Free

Spybot Search and Destroy

Spyware Blaster

Other well-reviewed anti-spyware programs (but not free) include:

Be aware that there are also many websites out there promoting anti-spyware software which claim to clean spyware off your PC, but they can actually install their own spyware and disable any anti-spyware software they find. This website, Spyware Warrior has in depth information, and lists of trustworthy and also rogue/suspect anti-spyware products & web sites.
