Spyware: What It Is

What is Spyware?

Spyware is Internet jargon for Advertising Supported software (Adware). It is a way for shareware authors to make money from a product, other than by selling it to the users.

Do I have Spyware on my machine?

If you've ever gone on the internet with your computer, mostly YES, you have spyware on your machine. You can get it by installing certain software or just by surfing the internet.

Why is it called "Spyware"?

While this may be a great concept, the downside is that the advertising companies also install additional tracking software on your system, which is continuously "calling home", using your Internet connection and reports statistical data to the "mothership". While according to the privacy policies of the companies, there will be no sensitive or identifying data collected from your system and you shall remain anonymous, it still remains the fact, that you have a "live" server sitting on your PC that is sending information about you and your surfing habits to a remote location.....

Are all Adware products "Spyware"?

No, but the majority are. There are also products that do display advertising but do not install any tracking mechanism on your system. These products are not indexed in our database. Adware isn't necessarily spyware. Registered shareware without ads may be spyware. Purchased out-of-the-box software may contain adware and may also be spyware. Updates may change a previously ad-free version into an adware product. All this makes for a confusing mess and users need to be on guard when installing any type of software.

Is Spyware illegal?

Even though the name may indicate so, Spyware is not an illegal type of software in any way. However there are certain issues that a privacy oriented user may object to and therefore prefer not to use the product. This usually involves the tracking and sending of data and statistics via a server installed on the user's PC and the use of your Internet connection in the background.

The Bottom Line:

Avoid adware. If you're broke and can't buy a clean shareware product, find an ad-free, non-spying equivalent of the program you need. Avoid spyware at all costs. Install a firewall and pay attention to what is asking for permission to connect online.

What are the symptoms of spyware

Spyware can affect a PC or network in various ways. Here is a list of common symptoms to help you decide whether or not you have spyware installed on your machine.

For Consumers

  • Slower PC Performance. One of spyware's many effects is the significant slowdown of the performance of your PC. Your computer may seem sluggish, take longer to start when you turn it on, or take longer to get to the Internet. For example, a computer with as little as two adware applications could take more than 14 minutes to boot.
  • New Toolbars. Certain types of spyware such as hijackers can add new toolbars to your Internet Explorer that you did not knowingly install.
  • New Desktop Shortcuts. Some spyware may add new shortcuts on your desktop.
  • New Default Homepage. Browser hijackers change your default homepage to a different default homepage. Some homepage hijackers may prevent you from changing your browser's homepage back to its original default or prohibit you from visiting certain websites.
  • New Search Results. Hijackers can also change the results of a web search and point you to designated websites that you did not request in your search.
  • New Error Pages. Error hijackers will display a new error page when a requested url is not found. Excessive Full-Page and Pop-Up Ads: Adware can inundate your computer with targeted ads based on web surfing habits that have been tracked. Adware can slow down your PC to a crawl.

For the Enterprise

All of the above and the following:

  • Slow Network Performance. Spyware robs your network of speed and Internet access efficiency. For example, a computer with as little as two adware applications could take more than 14 minutes to boot. This can significantly affect employee productivity.
  • Congested Network Traffic. Spyware transmits and receives information across a network causing significant overhead and therefore bandwidth waste.
  • Modified or Deleted Files. If you notice that files have been modified or deleted for an unknown reason, this could be the result of spyware.
  • Lost Control of PC. Certain types of spyware such as RATs can take control of a PC or an entire network.
