If you use your computer everyday, or at least depend on it for important functions such as emailing and researching, then you at least need some basic know-how of anti-spy software. There are several manufacturers who claim that their anti-spy software can protect your PC completely, but do they really? Here's what you need to know.
Anti-spy software works by scanning the entire operating system for all of the suspicious codes that may be harmful to your data system. When the anti-spy program detects any piece of suspicious code, it then compares it to the stock codes that are known as signatures. These signatures are deleted in file under those already trapped spy programs. Signatures are contained in a signature base, a vital ingredient of an anti-spy software. Needless to say, the more signatures your anti-spy software knows and keeps, the more protected your computer system becomes.
When Anti-Spy Software is Not Good Enough
Like the police departments in all locales, anti-spy software watches out and prepares to trap the "outlaws." But there are still some spy programs that remain "at large." These days, more and newer spy programs are generated. There are signature-based spy programs recently created that can not be identified by average anti-spy programs. And, once the code is unknown to your current anti-spy software, it will not be able to protect your system from possible corruption.
The best that you can do is to update your anti-spy software as often as possible. Do your best to backup your data so that if your hard drive crashes because of an attack, your can still retrieve your files.
