PC Safety (Special 1) Troubles
When I began my adventures on the Internet, all turned out to be fantastic, easy ... A world of open doors and opportunities to learn anything quickly and away from real life fears. Wednesday, March 31, 2010
Welcome Address In Schools
Obviously, it was an unsuspecting surfer and free from fear or fears, because "what I can pass through a computer?" I said to myself. Soon I began to see the dark side of the network and the risks that today we may suffer if we are not ready, predictable and apply common sense in the digital world to life. Virus useless left our teams, Trojans and malicious programs that steal personal information for use in fraud, theft of money through online banking, spam continues to get our mail, online shopping scams ...
is why we decided to create a series of guides or tutorials to present some guidelines to follow, if we enjoy the benefits of the network without fear of taking risks that unfortunately people have suffered more than we think.
Common sense
Real life is full of good things, but equally, we also find many other things that can cause injury. The experience and risk awareness make us walk with caution to different situations:
Who leaves his house without doors?
"surrender to any stranger the keys to your car?
Would you would trust someone who promises to give you a lot of money doing almost nothing?
The answers to these questions are self-evident. Of them can make it clear that we use common sense and the fact of keeping guard against such situations, greatly reduces the chance of scams, assaults, robberies, kidnappings or even in some cases. As in real life, our foray into the network should not be open to anyone. We need to create those same strengths and apply certain precautions to reduce the chance of all these attacks and scams.
A secure PC is a guarantee of peace
The first of the measures we should take is to protect your computer from external threats. In this regard, it is as if we have a house and set its doors, locks with key, windows, fences ... Let's say you try to keep our possessions safe, any threat that seeks to enter or take anything without our consent.
Currently there are different tools for each type of threat known. Each one is responsible (as you would at home) to deal with malicious programs that burrow and destroy your PC for criminal purposes or simply to do harm.
Firewall or Firewall
The firewall is a program designed to stop unauthorized data input to our computer, from internet or suspicious programs connecting to the network internally, warning and requesting permission to block or allowing such work.
could say it's like the security guard of a bank: if someone suspicious enters stop it, or if someone tries to get something in an unauthorized manner, blocks it.
Windows includes its own firewall, but there are separate tools that do very good job. Among them, we highlight the popular:
ZoneAlarm Security Suite 7.0.337.000 Antivirus
Perhaps the best known security program by any user. Viruses, in general, are aimed at other targets other than the spyware or adware (see below).
code files are created by hackers, which in most cases destroy parts of the structure of the operating system or prevent we can work quietly, with acts that alter the natural behavior of the latter.
Its distribution is based on the lack of common sense of society and used as the main method of concealment in containers of files that are downloaded from the Internet, but lately, they've evolved to take advantage of USB sticks for moving from one place to another .
I know that many people download programs, movies or games from the internet to avoid paying for the original. Hackers are aware of this and put them in keygens or password generators.
If a virus launches a virus alert, usually a virus, so is in your hands and letting this be installed on your computers (with the consequences that this carries) or protect you as you would do before the entry into your house to someone who already tuvierais suspicions.
There are many antivirus market to use. We have them paid and free, with more features or less, local and online ...
Choose one or the other is more difficult than we think, we all carry out their function in much the same way. So I recommend using free. Among the best known are:
Premium 8 Avira AntiVir PersonalEdition Avast! Antivirus Professional 5.0.418 Microsoft Security Essentials antispyware programs or Antispyware
Perhaps, today, this type of program are the most damaging and present. Spyware, as its name suggests, are small pieces of code that
sneak into your computer to find information, browsing history, passwords collection services ... and then send this information to its creators to try to get commercial , identity theft, social networking, obtaining e-mail listing to carry out spam, etc..
addition, these malicious programs use much of our computer resources and bandwidth, causing the computer and connection speed slows down very much.
As viruses are often hidden in data packets that are downloaded from the Internet, although we go through the mail or web page created for this purpose.
There are many tools that analyze and eliminate this type of adware and malware on the market. We have them paid and free, the most popular and effective in the second one:
Ad-Aware Free Spybot S & D protecting them from data loss
points described in the first part of our guide to navigating safely through Internet are very effective but not ruthless. Perhaps the infection of our equipment from one of these little programs does not affect too much of certain types of users, they do not possess documents or files of importance, but in other cases, we speak of users have stored on their computers relevant documents , photographs do not want to lose after formatting (By infection), videos, work files, etc.
always recommend to my friends and Configurarequipos users, backing up important files regularly. Most virus infections are difficult to remove, ultimately causing the need for formatting and data loss, it is therefore important to make these copies with programs that offer the possibility to carry out automatically and under a timetable.
Conclusions
In this tutorial we have learned one thing above the rest: common sense is stronger at the attacks that the tools exist to prevent them. Still, it is important to first be made on any new computer or operating system installation, be prepare all the security arsenal that will allow us to navigate the Internet safely.
far the first of the tutorials, we will continue with new guidelines on e-mail Security, Online Shopping ...

typical keyboard.
SHOOTING THAT USUALLY HAVE A KEYBOARD. 
The keyboard is not just a Computer components suffering more breakdowns, although if it is one of the most exposed.
Let's take a look at the damage that may have, and some of the fault, are not really failures, if we can leave this disabled.
There are three types of keyboard, based on the type of connection you have:
Keyboard PS / 2:
PS / 2. See the purple connector.
is the most common type of keyboard, and as the name suggests is connected to the PS / 2 keyboard specific. This port is the one closest to the outside base plate, usually indicated in purple.
Faults often have few, almost all caused by misuse.
The most common is that by putting the forces and twisting of the connector pin PS / 2, which is obviously useless. Given this failure
we attempt to straighten the pin that has been twisted and reconnect it correctly.
can also be the case that by forcing us to break the PS / 2 motherboard, although this is now rare.
The solution is often more difficult, since in that case it is necessary to unsolder and re-solder the connector, and this is a rather delicate task.
View of the PS / 2 connectors. Violet is the keyboard and mouse green. On your right you can see the USB connectors.
A third possibility is to break the controller PS / 2 motherboard.
This fault if we can not fix. Before
three faults have the option of replacing the keyboard with a USB-connected keyboard.
USB Keyboard:
USB Keyboard. In this case it is a reduced keyboard (88 keys), which is the type often used by laptops.
This type of keyboard does not usually cause many problems, except those inherent faults USB port (already discussed in the tutorial on
Malfunctions USB ports.
The main concern is that there are many motherboards that do not enable the USB keyboard to the Post, so no we can use it until you're in Windows. However there are many boards that if they can enable the USB keyboard directly into the boot, usually by an option in the setup (which is usually an option with a text similar to Enable
USB Keyboard ).
wireless keyboards:
wireless keyboard. You usually sold as Desktop , ie keyboard and mouse set. To the right of the picture we see the receiver.
is a type of keyboard, as its name indicates, is not connected to the PC via cable, but work normally by radio frequency.
depend on a receiver if it is connected to the PC via cable, and can be connected either PS / 2 or USB either, so it is likely to have the same damage with a keyboard connected by cable to the PC, to which we must add a few.
First and foremost (although not really a fault) is that we run out of batteries. This type of keyboard is not exactly cheap to maintain and the batteries do not last too long, To this must be added that have a nasty habit of not warning that they are running out of batteries, leaving in most cases abruptly.
The solution is simple. Replace the batteries and go, but if so we often find the second most common problem that usually give.
And this second problem is the frequency or lost sync with the receiver.
As we have said, normally this type of keyboard works by radio, through a receiver. Well, so they can communicate both must be tuned to the same frequency.
often work with a number of fixed frequencies and limited, so that system syncing is usually quite easy:
Both the receiver and the keyboard are a little button to change the frequency. This is press the button on the receiver and then press the keyboard until we match the frequencies.
Here if we can find a real fault, and this is has been damaged or the receiver or the sender of the keyboard, in which case there is usually no redress, much less at a cost that justifies the director.
In this category we can include wireless keyboards also new bluetooth keyboard.
These keyboards use this medium of communication with the PC, and have the same advantages keyboards via radio, most of it can be used in any device using a Bluetooth connection (and you have drivers for the keyboard), such as PDAs, some mobile phones, Tablet PC ... but also all its disadvantages, which must be added that in this case if you only work once the OS is loaded, and this in turn loaded the bluetooth drivers.
Well, so far we have seen different types of keyboards in order for your type of connection to the PC and the problems they can give. Now let's look at the generic problems that can occur in any type of keyboard, without having regard to the type of connection they use.
software problems:
The keyboard is a part not need driver, as it is supported by the device drivers the operating system.
While many multimedia keyboards have a CD or floppy disk with drivers, they are to activate some of the multimedia functions (not all, as many of them the supports Windows directory) and configure its use, not for the keyboard itself.
is not normal for this driver is damaged, but it is not impossible. In this case we will notify the operating system itself, and the solution is to recover this driver installation of the system. Usually recover deleted and letting the system re-detect the keyboard.
A common problem is that unconfigure. The solution to this problem is reconfigured as reloading the language and keyboard settings we use. This can be done from the Control Panel
and within this from Locale . Also
Control Panel, but in paragraph keyboard can set some options, such as the type of keyboard you use, repeat delay, repeat rate and cursor blink rate.
Windows keyboard settings.
Hardware Issues:
Well, the hardware problems that are motivated features a keyboard in the vast majority of cases for two reasons:
- Dirt that accumulates on it until it ends make it stop functioning properly and that is solved by cleaning, preferably with air.
- Misuse of the keyboard, due to shock and bludgeoning''.'' Although usually quite resistant keyboards are not unbreakable, so they end up giving up. In this case there is little basis except buy a new keyboard.
- Faulty keypad board, which is usually manifested by the malfunctioning of some keys. The arrangement is the same as in the case above, ie changing keyboard.
Ah, I forgot. There are three things in particular that they do not feel anything right on keyboards (and that is the cause of many faults:
Namely,
Coke and the like, coffee and beer .
On keyboards if there much difference in quality (and prices), and of course not the same brand keyboard (here we must make special mention of the brand
Cherry , although little known to many is the largest manufacturer of keyboards and one of the higher quality) and a certain price for a keyboard these economic (which is just over keyboards from 2.50 euros).
Among the top brands of keyboards can cite the aforementioned Cherry
, Logitech, NGS , Labtec , Genius and Benq , among others, to which we must add the keyboards houses of computers, which are usually of high quality, though sometimes hard to find, as is the case with HP , Acer, Packard Bell, Dell or Microsoft own.
Regarding quality, the palm is still carrying the Mechanics
keyboards, but have the disadvantage of not being very quiet. Keyboards Membrane have a quality getting better, are much quieter and significantly cheaper. That if good mechanical keyboard or hybrid (mechanical / diaphragm) is usually around 50 euros (not to be multimedia or anything).
Before closing I would like to clarify one thing. In many cases of failure, saying the solution is for a new one is on the ground that there is no market for keyboards parts and besides, unless we are''hands''and dare to try We repair, the cost of the repair work will in any case well above the cost of a new keyboard.

What Is A Good Signature For Funeral Flowers
Clean the CD-RW
HOW WE CLEAN UNIT recordable CD. When we get errors such as unwanted
calibration area is full or we get a nice buffer underrun or CD-ROM / writer of a sudden does not read any CD, or starts to "complain" emitting strange noises, etc.. despite having followed all the advice to avoid (and assuming that the unit already has at least one year old approx.), may be the time to make a "fine tuning" of the recorder (instructions are also valid for a drive type CD-ROM).
Cleaning the optical disk reading devices, such as tape recorders and CD-ROM, is a task far more relevant than it seems. If these units clean well and above all its lens, are fundamental tasks in its maintenance, once beyond the year-old or so (there are models that hold more and others not). And above all it has to do well, not crazy, because we could mis the lens, and that does not want to happen.
TOOLS REQUIRED: Ø
Phillips screwdriver to open the tower and remove.
or screwdriver small flat blade (width of 0.25mm).
Ø Two brushes, one medium (No. 10) and one small (No. 2).
or tweezers. Ø Several
hygienic cotton swabs.
STARTED:
opened the tower, remove the recorder, and proceed to remove the really small screws holding the casing of the recorder. Depending on the device, we can remove the skin from the top, the bottom or both.
FROM THE TOP:
Where to choose, we will remove the top cover, because then we can go directly to the lens, without do anything else. If this is your case, skip to clean the lens.
FROM THE BOTTOM:
We played a ground for static electricity discharges (the chassis of the computer power supply, for example). You can also use a more technical approach is to use a "shock bracelet", for it put a wire from the nearest ground and a 1MW resistor in series, and surround the wrist that will manipulate the optical welded wire (better internal antenna coaxial cable). So while we take the cable will always be free of static electricity.
Now we will see a large integrated circuit board with a series of cables going into the engine's CD-ROM. Remove the plate (secured with screws), being careful not to disconnect the cables, or, if you have to disconnect one, carefully where you sign each. Once removed the plate, we see the motor above the rails, and mounted above the rails, the lens. If you look all these components are in a kind of box set with the rest of the chassis by means of hooks. The front hooves are removed by prying, and pushing them back down with a small screwdriver. With this we will get all the cash, and we can work peacefully.

GENERAL CLEANING:
Before proceeding it is appropriate to emphasize the three rules of this phase of cleaning:
1 .- not under any circumstances touch the laser lens. If for any reason we noticed that we have touched lightly with some of the brushes should not be alarmed as there should have been out of calibration, but yes, avoid contact at all times.
2 .- not ever blow into the unit. In many instances, certainly more than one may be tempted to get rid a set of dust and dirt varies with a good blow, well, I just get with it is damage the internal electronics, as the human breath is composed, apart from the exhaust air of particles of saliva and moisture negatively affect any electronic component.
3 .- If cleaning is done with patience, knowing that last at least an hour, the operation will end with total success. In contrast, if done in haste, it is likely that the unit is clean and even come to malfunction.
VERY GENTLY blow up the lens and photoreceptor (if available). Prepare a ear cleaning stick, water and / or alcohol. Alcohol can be dangerous, since there is a plastic components made of very bad, which could react with the alcohol rendering them useless. Although very limited way, in fact I have not seen any. Recorders doubt there is any, and CD-ROMs may be the competitor. With distilled water works well, but you can also use isopropyl alcohol, because their properties in the chemical composition, make it especially suitable for these purposes.
Well, stick soaked with the product that we choose, without dripping. Next, carefully clean both metal guides were analyzed using the rods hygiene and product. We'll have to try to pour the liquid just to avoid a possible drain excess fluid in any area of \u200b\u200bthe drive electronics. Once clean, proceed to lubricate both rails using the lubricating oil specially designed for electronic devices, or alternatively, multi-purpose lubricating oil. In both cases we need to expand the right amount of oil as the excess can be carried by the laser lens, becoming deposited on top of anything sensible. It is certainly very little amount to be used is essentially a protective film and grease you have to expand, nothing more.

GREASE:
Theoretically there should be no oil, since it is assumed that the well-oiled unit leaves the factory (not always true). To see if this well oiled, you look at the rails by moving the lens. If you have a lot of dirt (lint, dust, etc) or fat has become like rubber (instead of being viscous) as it is best to thoroughly clean the rails, without leaving traces of the old grease, and apply some type heat-resistant grease, prepared for metal and plastic. Apply for all the tracks (but not fill all of fat. Excess fat is not good) and gently push the lens. If no resistance, move along the rails a few times to lubricate it. If there is resistance, we refrain from forcing it and after mounting the drive put an audio CD in it and go from first to last song a few times. Once finished the process, re-mount the drive with care.
IMPORTANT CONSIDERATIONS:
- Never clean the lens when the recorder / CD-ROM is under warranty, since opening means losing the warranty. In these cases it is best to take it to the store, you change it, and it cleaned them if they want.
- Do not go to clean the first problem I was present. Try before other solutions that do not involve opening the device as you open the device if not done right, can have worse consequences.
- Do not use cleaning CDs, since they are useless and may eventually reach the lens scratching or mis.
- Long eye to disassemble the unit. Everything must be done very smoothly, especially when handling the circuit board and to remove the lens box. Descargaos static electricity, which nobody does even though that puts it in all directions. Charge would be stupid for not wanting to drive for a few seconds to touch ground.
- If you are one of those you are afraid to open anything on the computer, you can always call a friend who knows. If you have no friend, a CD-ROM agenciaos old practice with him.
