This is a big question that many people ask and how does it affect the registry of the computer it installs itself on? Any software that secretly assimilates information about the computer it is installed on and uses the Internet connection of the computer to transmit this information to it's host computer is Spyware. Spyware usually downloads itself onto a computer through the Internet along with some other download that the user chooses. This is intentionally coded into the download for malicious purposes. The Spyware installs itself on the computer and runs in the back ground with the operator knowing it. Usually the only indication of Spyware on the computer is through free Spyware removal programs.
What does Spyware do?
Apart from slowing the system, as mentioned earlier Spyware programs are typically bundled into a program that is available as free ware and are hidden components in the downloaded program. Once the download is complete the Spyware installs itself onto the users computer and begins to monitor all the activities of the user. These can include recording the user name and passwords that the user uses or the kind of sites that the user likes to visit. Spyware always works in the background of the system and so it slows down a computer a great deal. Especially if the resources of the computer are low such as the RAM or disk space. Anti Spyware components are sometimes built into registry cleaners such as the windows registry cleaner or the PC registry cleaner. These programs scan the registry for malicious Spyware as well as for broken links and redundant data. They then clean the registry of this data and leave the computer running more efficiently and fast.
Unfortunately Spyware is not illegal in many parts of the world. So, nothing can be done to the company or person who is responsible for putting it there in the first place. At lease it the information is not used to damage you. The only way is to get some good free anti-Spyware software such as Microsoft Spyware removal tool and clean the system. The process is really simple. When the system has been scanned with some free anti-Spyware or Spyware removal program the Spyware can be removed.
