Spyware is the term used for software which is secretly installed on a computer, without the user's informed consent. The software then intercepts the user's interaction with the computer.
Adware automatically displays advertising material, such as pop-ups. It's easy to get confused between spyware, adware and malware, as many of the concepts overlap.
Although the term spyware suggests that the software merely monitors the user's behaviour, spyware may do much more than just that. Spyware programs can redirect your browser, install additional software or divert advertising revenue to someone else, as well as collecting your personal information.
A large number of companies provide anti-spyware software. Running effective anti-spyware software has become an essential element of computer security for Windows computers.
It is essential for your privacy that you eliminate spyware and adware from your computer. These programs also slow down your PC by cluttering up your hard drive and using memory. You should see an immediate improvement in the speed of your computer when you eliminate spyware and adware.
There are a number of programs available which will search your hard disk for spyware and adware, and will remove it for you. But it is better to not allow spyware and adware to be installed in the first place.
A computer firewall program is an effective way to prevent spyware and adware from being installed without your knowledge. These programs usually pop up a warning whenever new software is installed.
As 24/7 Internet access becomes more usual, it's more likely that your computer will be exposed to spyware or adware. A good firewall program will prevent programs from installing themselves without your approval.
