Spyware is basically any piece of software that is installed in your computer without your knowledge. They can do a number of things like for example, taking over a part of your system, say your internet browser and always bring you to their site whenever you type an address. There are multiple versions of these kinda programs. Another common one keeps track of what you do online and offline and sends this information to its own company, or sells them to other companies.

Spyware is installed without your knowing. It is able to change your homepage, give you massive porno ads, change your WALLPAPER (I know a friend that it happened to) and slow down your computer. Get rid of it using ad-aware. Also see saten, evil, geeks malware and adware

Microsoft Windows - You don't even know about it because it is in the OS. When installing Windows 10, it show a window where you can turn the spyware off. But they made it look like something that will help you, so many people are still spied on.

A Program that is created to steal personal information that is on your computer. Spyware is also used for advertising (Pop-Ups). The Best Adware/spyware Remover is "Ad-Aware" Its Free And you can get it from Download.com

The crap we find in most pop up blockers (believe it or not!) Gator E-Wallet and other things.
Let me explain what spyware is. First, it is a myth to say it that spyware is made to harm your computer, though I will explain why it eventually does. It is simply a tracking tool built into another piece of software, and by itself is harmless, though arguably, an invasion of privacy as it tracks your trends to report them to various marketing statistics companies. Fine, fine, we can all do a small part to help the economy this way.
However, with about a dozen or so pieces of software on your computer infested with spyware, all trying to track and submit marketing statistics at the same time, your computer becomes slower and slower. This is the harm that it does, and for some people their computer is an annoyance to use. Programs may take a minute to open, the computer takes minutes to load, and multitasking may cause the computer to freeze. The problem of spyware became a harmful problem, I believe, in the past year when many software companies added spyware to their software around the same timeframe. It was hard not to find software without spyware.
HERE ARE THE MAIN FACTS:
Spyware can track your Internet activity.
Spyware can change your search page.
Spyware can change your homepage.
Spyware can change your "not found" page.
Spyware can slow down your computer.
Spyware installs itself within another piece of software.
Spyware is not included in all software.
Some spyware is harmless while another can take more advantage of your computer's processing capability.
It is not the end of the world to have spyware on your computer as long as you are able to delete it.
Spyware is commonly found in (some) pop-up blockers, (some) browser toolbars and (some) other addons.

Spyware is also the common cause of dreaded infinate pop-ups. This happens when you find a link, click on it, and are spammed with "Page Not Found"s. The main way, and what I believe is the best way, to delete it is to use a Swedish (it uses English, but it was made in sweden) called Ad-Aware 6.0. The program is free unless you want an internet watcher with it. It takes only a minute or two to scan and the first time I scanned, I deleted over 500 files of multiplying spyware on my c: drive!
ALL computers should get scanned at least once a week, because I find my spyware multiplies 5 times a day.

software that collects personal information about the user be that mining one's workstation or monitoring one's behavior

voluntarily using such software makes it no less spyware

spyware is malware

gay shit made by assholes that will hopfully go to hell for their greed (if there is a such thing as hell)

fuckers who try to trick you by putting ads on webpages saying they will actually help your computer with their software when really they want you to download it so they can get info about you and fuck you and your computer over. and some people are dumb enough to believe them.

but sometimes they can get in your computer manually. spyware usually hides itself in photos, internet pages, ads, and videos. oh and if an ad suddenly appears while you're surfing, and has no title and tells you that you have spyware on your computer, that's spyware and you have it on your computer.

don't download that program. use real programs to delete that trash, programs such as adaware spybot prevx1 etc.

Piece of shit programs designed to track you down and collect personal information.
Hijackthis! and AdAware pounds it to dust! Yay!
