Spyware by definition is any program which tracks users and sends data on their computer usage to an unauthorized host. These programs may track typing, ("keyloggers," which can record any information, including passwords that might be sent over encrypted data streams) browsing habits (which can be sold/given to online advertisers to give you targeted ads) or information contained within your computer's software. What makes spyware particularly dangerous is the way in which it often infects systems with no warning at all to the user.
A misconception about spyware is that it spreads from computer to computer in much the same way as a virus--which is to say, through e-mail or communication between computers. Instead, spyware is typically installed through deception, as spyware producers tack their programs onto legitimate files which are then run in tandem when the user activates the legitimate file. Spyware can also be found on the net, as certain sites have been set up to exploit browser vulnerabilities and force the download of spyware on users who don't realize their computer is downloading the file.
Note that Internet Explorer is extremely vulnerable to these attacks, although Microsoft has recently made an effort to curb the vulnerable reputation of their browser. Regardless, I recommend using a different browser with less susceptibility to spyware and script attacks, such as Firefox, Opera, Safari, or Google Chrome. For even more protection, install an adblocker--"Adblock Plus" for Firefox, "Adblock" for Chrome; one can block ads on Opera manually or by downloading block-lists, though nothing similar to the extensions listed for Firefox and Chrome exist at this time for Opera to my knowledge.
By and large, the biggest problem with Spyware is that few people recognize how dangerous and frustrating it can be while engaging in unsafe browsing habits. As long as you understand how spyware works and take minor actions to avoid it, you should easily be safe. And the best way to stop the attacks of spyware, try this great security tool. It willl help you.
