Many people wonder what adware is, how it gets into their computer systems, and what its effects are. If you are an Internet user, your computer is most likely to have been infected by an adware program. Furthermore, if you have downloaded freeware or shareware from the Internet, it is almost certain that you already have adware installed on your computer.
These forms of adware are generally harmless and are sometimes required for certain programs to run. However, adware can also include spyware components, which make it a dangerous presence on your computer.
Without help, there is no way for you to prevent the installation of adware n your computer. Some older antivirus programs do not detect the presence of adware simply because they do not consider them a virus or worm. You will need newer antivirus programs to specifically target adware and spyware. Today, there are also adware filters available for sale or download.
Adware filters are essential to computer security. They automatically remove programs that attempt to install adware into your computer. They also block the download of programs that contain adware.
Some Internet service providers offer adware protection to their customers by providing them with a built-in adware filter, which is activated when the user is browsing the Internet. However, to take advantage of these filters, customers will need to upgrade their anti-adware programs and keep their anti-adware signatures updated.
Most adware cannot be installed without your permission. However, certain software may trick you into clicking a link that will download adware to your computer. Links that install these adware and spyware programs can be very misleading, so you have to be extra attentive around them. The only way to prevent infecting your computer with adware is to install software from trusted sources or those you know to be adware-free.
