What is Adware / Spyware? how to Prevent Adware / Spyware?
Are you a frequent Internet user? Do you download and use many free software and applications from internet? If YES, then be aware that your information may be stolen without your knowledge. Understand that those information that you willingly give may be sold to third parties.
Programs capture your personal information
Most of the free programs and software that you download from internet fall under any of the following Categories; Shareware, Demoware, Freeware or Adware. Among these Adware is usually the most doubtful and dangerous program. Adware stands for Advertisement + Software. Hence, if you install a downloaded program that is an 'Adware' then you will see many advertisements on your computer. And your personal information will be sent to these advertising companies by this adware automatically.
When you install these adware software it will bring you to that company's website to register with your personal information before you can use the software. This is called 'Registration for software activation'. To activate such software you HAVE to give your personal particulars. This information that you submit to such companies will be later sold to third parties.
Your information is stolen through websites:
Many websites and programs that you download and install will monitor your activities when you are connected to the internet. For example, details like which websites you frequently access and which links you click. Based on this collected information you will be judged and categorised and you will be sent SPAM emails that target your interest.
A frequent trick used by these softwares it to show a 1x1 pixel GIF image which is invisible to your eyes. But this GIF file will contain Scripting Code that does all these spying activities.
