What is Spyware?

Differences between viruses and spyware?

While both are installed on a computer, without the owner's knowledge, and can both negatively affect a computer. Viruses act like a biological organism by infecting a computer and replicating themselves, then spread these replications to as many other computers as possible. Spyware, on the other hand, want to "move into" a computer and stay as long as possible, sending as much of the owner's personal information to an outside source.
 

Where do these types of malicious, and unwanted, software come from?

Any of these malicious types of malicious software through the Internet.

Spyware usually is installed through free software, such as file sharing, mainly by Internet.
 

Can I get malicious software without knowing it?

Yes! Malicious software can be installed through embedded script or program on a web site. Web pop-ups, that ask the user to download a file/program, can only be installed with the user's help. Yet if Windows is kept up to date and security settings are in no way reduced, infection chances are brought to a minimum.
 

Why is it important to view license agreements before installing software?

When visiting websites, do not immediately agree to download anything the site offers. If downloading anything, remember to review the licensing agreement. Look for anything that says that the user must accept advertising and pop-ups from the software company, or if the software will send certain types of information back to the software published.
