Spyware is a type of software designed to break into a computer system to collect information about users' browsing habits and their computer without their informed consent or knowledge. A spyware blocker detects and stops such spyware from entering the computer. If the spyware is already in the computer a spyware blockers also clear them out of it.   

    The spyware blocker protects the computer in real-time. A spyware blocker is fully functional right from the moment you start the computer on to the second you shuts it down. Thus a spyware blocker sees to it that every file in the computer is scanned. The same applies to every bit of information the user accesses to and even to those already downloaded.   

    The capability of a spyware program depends on its programming. The programmer must have designed it to serve some specific needs. If programmed to track every operation done by the user on the computer, it will be done so. Hence, if you are unaware of what the spyware program is up to, it can even steal your identity thereby inflicting unimaginable damages to you and your computer.   

    A good spyware blocker will prevent any malicious software from being installed in your computer. Even if the spywares are smart enough to penetrate this defense, an effective spyware blocker will detect it and clean the system.   

    Most anti virus also have anti spywares with them. However, they are not as flexible as spyware blockers. They also take more time to detect and remove spywares as compared to spyware blockers. This is because spyware blockers are designed to immediate recognise and remove spywares, including the existing ones as soon as they are installed. Anti virus programs need to be updated to do this.   

    Users must update signature of their spyware blockers every two to four weeks. Only then can the spyware blocker function effectively. In case the program is not equipped with an inbuilt scan scheduling capability, it is better to perform scans by yourself and report it to the blocker.   

    The spyware blockers are constantly upgraded every moment in pace with the up gradation of technology. Hence, the battle against spyware is an ever-continuing one. Anybody who is in search of a good spyware blocker program will have a host of questions in mind. The challenges they will have to face are also equally numerous.
