Fortunately users of computers and, more specifically, the internet are becoming much more aware of the threats posed to the security of their systems.
And so they should.
That is because as many as 80% of computers may have their systems infected with spyware.
If you think about it that is a huge number of infected PCs and, what is more, most of those users are blissfully unaware of what is lurking on their hard drives.
This is hope, however, in the form of antispyware if only the uniformed knew that they needed it in the first place!
Antispyware prevents spyware from damaging your computer in two ways – prevention and solution.
In the ideal world antispyware prevents spyware from ever being installed on your system in the first place.
Some antispyware tools achieve this by scanning every piece of information that passes through your computer.
Everything it finds is then referenced against a database of all currently known spyware to see if their is a match.
This means that if any known spyware attempts to enter your system it will be immediately thwarted.
This disadvantage of such a preventative technique should be obvious though – if it ain’t in the database it ain’t gonna get detected and spyware does evolve quickly, just like viruses do.
A second preventative measure utilised by antispyware is to limit the activities of certain programs and applications that are known to be used in distributing spyware, one such example of which would be ActiveX.
This method means there will less chance of spyware entering the system surreptitiously.
Antispyware tools are also able to deal with spyware that is already resident on a system as well via regular scans.
When found, all traces of the spyware are then deleted.
From a programming standpoint solutions are much easier to incorporate than preventative measures because of the fact that most spyware is introduced into systems via common processes that are natively employed by the computer anyway, such as via Flash which has many quite legitimate uses.
For that reason you wouldn’t want to disable Flash and so antispyware has many constraints to work around.
The only other real means of limiting spyware, besides the software solutions, involve cutting oneself off from local and external networks.
Can you imagine not being networked or connected to the internet in today’s age?
Didn’t think so!
So, as you can see, preventing spyware is not perhaps as easy as you may have first imagined but you can prevent it with the right tools.
More on those later…
