To properly answer this question you have to know a little bit about spyware and what it actually is. Spyware programs are computer viruses that infect your system for a number of different reasons. Quite often a spyware program is designed to 'spy' on the information you keep in your computer. They can also be used to harvest that sensitive information and report it back to the virus inventor. Spyware can also be used to obtain specific patterns associated with common keystrokes that are being used and to establish online browsing habits. Most people are unaware of how common keystroke information and online browsing habits can be harmful to them.
If a spyware program is installed on your computer and is successful in retrieving the common keystrokes you use a computer programmer that knows how to decipher this information can then attempt to determine what passwords you have set up for the different programs and accounts you have on your computer. Your browsing habits are just as important to a virus creator. They establish specific patterns for your online habits, which websites you visit more frequently than others, what types of products you buy, how much money you spend while shopping online, they can even be used to determine how often you monitor your bank accounts and actually take notice of your account transactions history. All of this information can be harmful if placed in the wrong hands.
So, the question remains, “Can you permanently remove Spyware with an Anti-Spyware removal tool or program? The answer to this question is still complex. On the one hand you can permanently remove any known Spyware definition that the Spyware protection software is aware of and has the information necessary to locate, isolate and remove. On the other hand, Spyware programs are no different from any other type of virus in that there are newer versions being created all the time which are then launched and distributed containing new virus definitions or malicious code, which has not been updated into the existing anti-spyware program, which in turn will leave your computer exposed to the possibility of infection from these new viruses.
The biggest problem associated with a computer catching a spyware virus is the person using the computer in the first place. Bad Internet habits are the root cause for the continuation of virus infections. People are either too busy to practice good browsing habits, have no idea what good browsing habits are or they simply elect not to use them because they have an antivirus program on their computer so they have become lulled into a false sense of security. There are several steps each of us can take to limit the amount of risk we allow our computers to be exposed to.
Open source networks, such as social networking sites, video and file sharing websites, and live streaming video websites all pose a potential threat to any computer being used on their network. Avoiding these types of websites altogether will seriously reduce the risk of a virus infection; the problem is that almost everybody on the Internet has a Facebook profile, either for personal or business purposes or both. It has become a very useful advertising tool, for legitimate companies as well as for virus creators. Using extreme caution when accessing your profile on any of these types of sites will also reduce the risk of virus infection. Don't download any type of file that has been shared over these networks. Anybody can access them and attach malicious computer code in the form of a virus definition and re-share them on their profile page, before too long the virus has infected not only your computer, but the computers of your family and friends. Installing and properly using an anti-spyware program will increase the amount of security your system has; however developing good common sense browsing habits is just as important if not more so.
