In the good old days easily detectable worms and viruses were the main threat for your Computer and the data you keep on it.
Meanwhile a new, more harmful and less easy detectable threat has been developed.
This menace is called spyware.
Although viruses and worms are still a major harassment for your Computer, you should pay particularly attention to spyware, because most programs capable of removing spyware also remove viruses.
The reverse is not always guaranteed.
But what exactly is spyware and why do I need to remove it from my Computer? Generally the term spyware refers to programs that get installed on your computer without you noticing it and then transmitting data about your surfing behavior or even whole documents to servers that could be anywhere in the world.
Later on that data gets analyzed and is used in harmful cases to optimize websites in regard to place advertisements.
In unfavorable cases confidential documents, which you keep on your Computer get in the wrong hands and one just can imagine, what might happens then.
The good news is, that you can protect your Computer thoroughly and efficiently from unauthorized access.
There is plenty of software on the market, which you can use to detect and remove any spyware that might have gotten installed on your PC.
The only problem is to find an easy to use but still effective anti-spyware system.
The most important reason why you should focus on convenience when buying an anti-spyware software is, that after a little while you will get annoyed by adjusting and updating the spyware detection and so the protection will be less efficient.
Thus when buying an anti-spyware software keep in mind, that automatic scanning for spyware and updating the database should be more or less automatic.
