! See, once your computer gets connected with the global net it faces various threats and attacks from unfriendly microelements walking freely through the cyber space and seeking for new victims. It doesn't help if you wash your hands before touching the keyboard; the little monsters called computer viruses could be defeated in their own methods. This is where the sword and shield aren't able to help your romantic tendencies and the only way to eliminate this gross injustice is to accept a battle with electronic weapons!

While computer viruses behave pretty much like biological ones, they need special treatment that admits no analogy in biological terms. As insidious as their biological correspondents, they infect every living cell and spread around in record time. Thus, if you really need a functional pc, you should procure some electronic pills to get your work safe.

In this case you cannot become a faithful guardian to your machine until you have installed an antivirus program skilled enough to detect viruses, worms and Trojan horses - all “trustful” members of a happy family! It is important to keep clear about the differences between these sorts of malware, in order to protect your computer from them all. Viruses, as we used to know them when first dealing with a computer are no more that widely spread since the Internet became popular. Once again: you need an antivirus that helps against viruses, worms and Trojan horses (not only viruses)!

See the slight differences in methods and effects:

Viruses intend to destroy your data. They act in sly movements and this is how the predominant negative effect of viruses is their uncontrolled self-reproduction, which wastes or overwhelms computer resources, until your cyber work space doesn't leave you room for your actions.

But since we've got Internet connection we have to deal with the most popular visitors from “out there”! Introduce yourself to malicious worms: worm uses a network to send copies of itself to other systems and it does so without any intervention, thus, you stay helpless face to face with it. In general, worms harm the network and consume bandwidth, whereas viruses infect or corrupt files on a targeted computer. Viruses generally do not affect network performance, as their malicious activities are mostly confined within the target computer itself.

And here is the moment when the masquerade starts: Trojan horse is a malicious program that is disguised as legitimate software. Trojans use false and fake names to trick users into dismissing the processes. In most cases the program performs other, undesired functions, but not always. The useful, or seemingly useful, functions serve as camouflage for these undesired functions.

While some of them are particularly benign or simply annoying, others are extremely harmful and deadly dangerous. In analogy, just compare a regular cold with pneumonia… no need to mourn for you computer! What it really needs is an anti-virus protection. Remember, they are active in this certain moment, when you're peacefully typing.
