Test: Symantec Norton Internet Security 2010

Norton Internet Security 2010 from Symantec is the new version of the world's probably most well-known security package. This year has trimmed the software package further, and brought several smart features to protect against new threats that come from the Internet.

Security companies have been asked to start thinking about when they build their antivirus software. Viruses do not work at all the same today as it did a few years ago. In 2003 they found about five new viruses a day. Today it released about 25 000 different types of viruses, trojans, worms and other dangerous code - every day! Viruses write about themselves and create new versions automatically, to make it more difficult to identify them.

In order to offer better protection against today's dangers on the Internet is no longer just relying on the so-called definition lists , or signature files. These are databases containing information on all registered viruses. In order to keep their antivirus software needs to continually update this list. Are we a couple of years back in time this took place about once per day. Norton Internet Security 2010 update itself about every five minutes.

But this is not enough. Therefore, antivirus programs today are increasingly moved towards the work in the cloud. By this means, briefly, the program communicates with the manufacturers' servers, thereby exchanging user information about files that are downloaded from the Internet. This is done automatically and there is nothing you need to worry about, but it gives you just simply a much safer and better protected.

Symantec technology called Quorum. Today there are tens of millions of Norton users worldwide sharing of information. Loot a dangerous file by a user in Costa Rica, another user in Säffle be protected against this in minutes. This is totally the way to go.

Increase the battery life of our laptops: you can, with some changes

• 

Although the technology is always great strides, the problem of battery life remains and will always, inevitably, a big problem that will probably only if inventing, science fiction, air batteries.

Each user, in fact, know something about. As prestantissima, highly efficient and modern, the battery in our laptop sooner or later you download, and happen well after a year, is inborn in us the fact that, ultimately, our intellect would ponder why it is spent so little time since we started our work session last recharge.

Miracles, it is clear, you can not. But a little 'with the help of the integrated features of the latest operating systems to promote energy conservation, and a bit' with the help of a few tricks you can do so much. And just a few simple trick, like those that we present today.

1) Lower the screen brightness can be the most immediate measure. Consumes more than a 200 watt bulb (and somehow never becomes increasingly rare to find them, thankfully!), Or 40 Watt? The answer is clear .. And what an example might be a bit 'rough when we fail to illuminate the whole house with the light of the laptop, we will certainly sin.

2) Disconnect the devices connected to your laptop, if possible. It 's a simple but rare thing: how many times we leave the USB stick attached to the computer even if it does not serve us? Everything is connected to the pc, draws energy from it. The consequences are implied.

3) Remove unnecessary programs and close automatically since those not in use. The number of open software affects the battery life of a laptop. Close programs that do not serve us, is a great way to save energy.

4) Use the hibernation (most of the stand-by) if for a limited period of time we do not need the PC. If we make a phone call, for example, should certainly not turn the PC on which it is working. But if you use a tool to limit consumption to a minimum while leaving unchanged the status of the notebook, what harm would we do?

5) Turn down the sound when necessary, and prevent the opening of multimedia content, wherever possible. Unless the neighbor is not quarreling with his wife, you must rinsordirci with loud music or videos that start even see? Seems not to consume, but these files virtually "kill" our battery.

6) Recharge the battery before it "dies" completely. Our battery lasts longer if the reload is low but not when scarichissima. The modern battery models have more memory effect, and not necessarily that we have to wait for them to load completely exhausted.

Many others, then, the devices can be smaller, sometimes indirectly. Examples of this kind are defragment the computer often to improve performance and timing of the computer, expand the RAM to use less SWAP, lower the graphics capabilities of the operating system when not needed, clean the vents of the notebook, clean the contacts of the battery.

Ecologists, savers .. but most users do not remain, as they say, "walk" for improper use of the computer. This also, unfortunately, sets of characteristics of good requirements-user laptops. Let us treasure, never wrong.

Compendium on how to buy a relatively cheap laptop

How to choose a notebook of this type? It is not always simple. Draw in some general guidance on how to evaluate the hardware in your laptop to buy. First, the motherboard. Unfortunately, disentangling the myriad of cards that produce today is difficult, sometimes even for those handling hardware for many years.

Not to mention that for notebooks often the information on this component must be specifically requested and usually the large chains (ipercoop, Euronics, mediaworld etc.) most often do not provide accurate data because they consider them indispensable to their customers or many times have employees with knowledge to provide comprehensive explanations ...

In fact, the motherboard is essential and it may depend on the quality of the purchase that we are going to do. For the average user, we can say that it is good to consider the possibility of expansion provided by the motherboard, such as the number of slots for the ram, in case you want to expand it, and the maximum capacity for each slot (for example, some cards support up to 1Gb per slot, others up to 2GB), memory for those who do not know that the slot is the single slot where a card is inserted ram.

It 'also important to know the types of ram that can support, for example some motherboards give ample opportunity to frequencies (without getting too technical in the frequency depends on the speed of the ram), others allow only a few, such as for DDR2 we find the DDR2-400, DDR2-533, DDR2-667, DDR2-800, DDR2-1066 (the latter less common because normally goes on to DDR3 technology), the index is a numerical factor that represents, even if it is a method assessment somewhat 'simplistic, the speed of the ram.

We should also carefully choose the motherboard based on the choices of frequencies supported ram, the more it expands better choice. Another important feature that we consider, depending on the motherboard prerogative in our notebooks, is the presence of an integrated video card (shared memory), or the possibility of having a dedicated video card (better performance).

Last thing to consider is the type of processor that your motherboard can support, especially linked to the type of technology, such as a dual-core processor will definitely not be implemented in a motherboard that supports monocore classic, and also in the case of similar technology there will be limits of performance (processor installed) well defined in the technical details of the motherboard. We will discuss in the next part of the compendium, a concrete example of hardware configuration for low-end notebook (very low cost), with a special mention in-depth hardware discussed in this second article.
