Spyware / adware

The internet is great as a forum for people to share information and helpful programmes they’ve developed. Unfortunately something that looks helpful or fun like browser toolbars, weather programs and screensavers might be masquerading as a carrier for spyware or adware.

Spyware is software designed to spy on your online activity and ad ware is software designed to install pop ups and advertising on your computer.  Many of these viruses do both.

What is spyware / adware

At best, the spyware can be fairly harmless - it might collect information about your browsing habits and display advertising targeted to your interests (adware).  Even so, it does feel like an invasion of privacy and it may well slow down your computer.

At worst, spyware can be malicious, it may scan your hard disk to try and capture your personal information, such as banking details and passwords, and transmit them to criminals.  It may also try to shut down your anti-virus or anti-spyware programs.

Ways to tell if you have spyware / adware

• You see pop-up adverts (adware) even when you're not browsing
• Your browser's start page or search settings change without warning
• A new toolbar appears in your browser that you didn't expect or want 
• Your computer starts to run more slowly or crash more often

How to avoid spyware / adware 

If you follow this advice it will also help keep you safe against other online problems.

1.  Download and install anti-spyware protection

Microsoft offers a free anti-spyware program, Windows Defender, to Windows users.  Other software providers offer similar products - any reputable computer software supplier can recommend the most suitable one for your system.

Find out about available anti-virus/spyware software.

2.  Keep your software up to date

Make sure the software on your computer, particularly the operating system, is up to date.  If you're running Windows, you can download updates from the Microsoft security site.  You can use this site to allow your computer to receive updates from Microsoft automatically, so you won't have to remember to download them.

3.  Surf and download safely

• Only download programs from websites you trust.  If you're not sure whether a particular program is safe, you can enter the name of the program into your favourite search engine, to check if anyone has reported that it contains spyware
  
• Read all security warnings, license agreements and privacy statements associated with any software you download
  
• Never click 'OK'  or 'I agree' in a pop-up window on the internet unless you are sure what you are agreeing to
  
• Be wary of 'free' music and movie file-sharing programs and make sure you understand the software that comes packaged with these programs
