what are spywares? How do they afffect the computer's performance?

Answer 1

spyware/adware look at what you are doing and report it to whatever company and they may give you pop ups of what you like or however else they want to get their product across to you. Then there are some that even send personal information. These programs run and you dont even know it and make your computer slow. That's why getting a good spyware program is a good idea. The free ones are ok, but not good enough. If you use free ones i would use 2 or 3 of them. Spysweeper is the best out there hands down, but you have to pay for it per year. its not expensive either and comes with virus protection too and stops it before it evens gets to your computer, unlike the free ones...

Answer 2

Spyware" has come to be a generic term used for unwanted software that is installed on your computer while using the Internet. The earliest "spyware" (and where the name comes from) would keep track of your Internet usage, and sent that information back to the creator of the spyware. That info could be used to sent you spam or popup ads related to things your surfing showed you were interested in. (If you go to music sites, you would get music spam and popups).

Newer ones can cause popup ads to appear on your PC, steal other information about you (passwords, credit information, etc), give you non-stop false virus warns and try to sell you the "cure" for their own program and redirect your browser so that it continually goes to the spyware owner's web site.

They can slow your PC (the more programs running, the slower the PC), slow your Internet connection (because they are using it to send their information), cause non-stop popup ads, and even steal information (and money) from you.

Answer 4

Spyware is computer software that collects personal information about users without their informed consent. The term, coined in 1995 but not widely used for another five years, is often used interchangeably with adware and malware (software designed to infiltrate and damage a computer respectively).
