This is the reason why, there exists a need for an advanced registry cleaner tool, which can detect all the errors and enable you to maintain a healthy registry.

Let’s discuss some more facts about registry programs and identify the reasons for a registry scan. A registry maintenance tool comes with a user-friendly graphical user interface. Therefore, even if you are a non-technical user you can use it to easily fix your system’s registry on regular basis.

You must possess a tool, which is based on highly advanced and complex algorithms while is simple to use. An effective registry cleaner tool would enable you to identify all inaccurate, unwanted, and malicious information contained within the registry of your computer.

An advanced registry cleaner tool helps you detect registry-related errors in a user-friendly way, while allowing you to identify and delete all invalid entries. In case, you don’t know which entries should be deleted, you can use the automatic repair option, which would automatically fix these errors for you.

An advanced registry cleaner tool enables you to identify and implicitly fix several other computer-related errors including driver errors, ActiveX errors, stop errors, and DLL errors. This is because the advanced algorithm used in an advanced registry cleaner enables you to look for keys, which are entered as non-removable keys or embedded keys.

These keys store licensing information within a software application. Because of this, many spyware programs enter data in these keys so that it becomes really difficult for the user to remove them from the system.

It is highly recommended to run a registry scan once you have uninstalled an application from your computer. This is because when an application is removed from the system, it is likely to leave behind several stray keys, which might muddle the registry. Therefore, a registry scan after the un-installation process is over helps you identify and get rid of these useless keys.

You can also defrag your registry by using a registry cleaner tool. Defragging allows you to reindex and compress registry files and remove undesired orphan keys left. If you want to reduce the size of the registry, you must appropriately scan your registry and compress it by using the registry defragmentation process.

The registry backup option is one of the most dependable features of a registry cleaner tool. This is because it takes an automatic backup of the entire registry before starting with the repair process. As you have the registry backup with you, it’s easier to restore your registry anytime you want.

This feature is highly beneficial in case your registry cleanup activity fails. A good registry tool also contains an Undo feature, which allows you to undo the registry edits. Also, you can use this tool to perform a complete or selective registry backup to match your needs.

There are many registry cleaner tools which allow you to perform additional system maintenance activities including managing startup programs, Internet Explorer files, and un-required system files.

Intruders are getting their hands on the latest security measures brought out by various developers and are looking for ways to get through them.

Anti-virus software developers are doing their best to ensure every computer user’s safety and security from potential attacks by always updating their virus definitions and cleaning capabilities, as well as strengthening your firewalls.

Sometimes however, it is not enough as intruders can be one or more steps ahead. They use various means of attacking computers so it is sometimes hard to tell what they’re going to do next. One of the ways is hacking in order to retrieve your password.

Think of the many things they can do once they get your passwords – they can access any online accounts you may have, access your email to send and retrieve messages from your address, enter secure networks – the possibilities seem to be limitless. In order to prevent these things from happening, you should have password protection.

The first thing you should do is secure your files and folders by using any password protection software, especially your highly important files and folders which could be potential targets of intruders. If these files are left unprotected, it would be easier for these intruders to get a hold of them and do what they want.

Aside from that, other users of your computer (example – your kids) can accidentally move them or even delete them, which can be prevented by password protection.

Hackers and intruders would have an easier time figuring passwords out if they remain the same for a long period of time. It would be better for you if you change passwords regularly, especially for your more important data, for added security.

By doing so, the intruders would have to start over again since you have a new password, thus making the possibility of frustrating them greater.

It would also be harder for hackers to figure out your password if you use a number of different characters, especially if it is a combination of letters, numbers, and symbols found in your keyboard.

Of course, it will be harder for you to remember a combination of these three also, so you have to make sure to memorize the combination, more so if you regularly change passwords.

A useful tip: it is recommended not to use passwords that are codes like your birth date, spouse’s name, or other relevant information because it can make deducing your password quicker and easier.

These “coded” passwords are often used by a lot of people, particularly in ATM machines and email passwords. By doing this, you are more susceptible to attacks since the password is easier to figure out.

Aside from following these tips which you can do on your own, it would be to your benefit if you obtain a password encryption software.

The meaning of encryption is that it disguises the password written in cleartext format into ciphertext, which is a combination of different symbols. Decryption is what the intruders try to do, which is change the ciphertext into cleartext that they can see and understand.

A password encryption software, which is available in the Internet via online purchasing or in your computer software shop, encrypts your passwords in order to discourage intruders and prevent them from accessing your password protected files.

Various software come with various levels of security, some of which contain a higher level of encryption than others. Higher encryption levels would make it more difficult for the intruder to break in.

Your PC safety and security is not limited to anti-virus software, anti-spyware software, and firewalls, because the passwords themselves can be targeted by unauthorized people.

It would be better for your overall security if you take the necessary precautions and means when it comes to dealing with password protection.

Securing your important files and folders with passwords, changing them regularly, using a combination of characters, and encrypting them through a password encryption software, would ensure your safety from password hackers.

Given that it is a part of their daily lives at school, it naturally follows that we can’t keep them from their computers at home so they can do research and homework on it.

With that in mind, we have to keep a close watch on the things our kids do online so that they don’t unwittingly become security risks in this day and age of computer-related crimes.

There are two types of programs that will help our home security over the internet immensely; the first is firewalls, which keep out viruses and spyware that our kids may accidentally touch on in the course of conducting their research.

The second is child safety software, which are programs especially geared towards helping parents monitor and control their children’s online time. Here are the top three free picks for firewalls and child safety programs you can download.

Firewalls

1) Comodo Firewall - one of the top picks among both free and purchaseable firewalls, comodo scans all incoming internet traffic before actually allowing it to touch any other part of your PC. It’s main feature is a program behavior analyzer that detects if programs have any unusual activity that may signal a virus or worm in the program. For inert viruses it also has a trojan protocol detector that is constantly updated online.

2) Kerio - this is a software that has been reported by users to offer them minimal headache in operation and use. While it’s protections aren’t as sturdy as some other firewall programs, it offers reasonable defense nontheless. It’s main strength is it’s ease of use, so that you can teach your children to operate it, giving them the benefits of learning internet security early in life.

3) Zone Alarm - ZoneAlarm is designed to protect connected pc from hackers. It will monitor all your activity and alert you if there is an application that attempt to access to internet.

Child Security

1) EZ off - this program is essentially a time management software for your computer. It will automatically turn the PC on and off at scheduled intervals, allowing you to control how much time your children spend on the net. This is best used to keep your kids from playing video games past their bedtime. The timer also features a calendar and scheduler, so that you can even keep the PC running for set intervals when you’re not at home.

2) Windows Supervisor - this software is all in one pc / internet activity monitor’s software. This monitor is used to monitor all logs made on the computer. So you’ll be able to tell what activity was running when they were there, including what sites they visited, files they up or downloaded, programs executed, and even keyboard typing done.

3) StopGame - for those who want to let their children enjoy the internet from time to time, a less-strict version of EZ off is similar to a firewall in that it lets certain, specified programs and web sites be accessed at certain times of day by the computer.

If your kids are, for example, doing homework from 6pm to 8pm and you let them have game time from 8pm to 10pm, you can set this program to allow them access to certain games (that you specify) from the 8 to 10 slot.

Opera
Opera is another free internet browser that allows you to load web pages quickly.  It also has plenty of extra features that let you have fun while browsing.  Like Firefox, it also uses tabs and a built-in pop-up filter and Google search.  If you don’t like the way your basic browser looks, you can even change ’skins’.

If you’re currently an IE user and are switching to Opera, this browser even lets you import your IE settings and e-mail clients.  The user interface is designed for ease of use and secured browsing.  Once you start using it, it shouldn’t be long until you find you’re breezing through the World Wide Web with ease.

Other browsers
There are other internet browsers that you can use such as Netscape, AOL and Crazy.  How well they perform from your perception will depend on what you expect them to do and what you want out of your internet experience.  Consider the type of internet usage you have when choosing your browser.

What to check for when choosing a video card

1. Determine how the computer will be used.
   Is it for computer games or just for ordinary encoding?
   If you use for computer games, check the latest game requirement for video card. There are different types of video cards for different uses.
2. RAM is resolution required to meet the video output needed.
   The memory of a video card is important for speed. Because it holds the common operands for the images. Since the video card can access its own memory faster, the images are displayed faster.
3. Motherboard and Video Card format compatibility
   A motherboard does not support all kinds of video card. Some mother boards only have the GPUs or graphics processing units which maybe adequate for an average business or home use but not applicable where more graphics capabilities are needed.A GPU is video card’s own processing unit.
   Mother boards may have the following expansion slots: AGP Slots, standard PCI slots, 1x PCI EXpress slots, 16x PCI Express slots. Make sure the video card and the slot where it will be installed are compatible.
   The 16xPCI Express slot has compatibility with the most video cards, so it is advisable to buy this card for a new computer. The next newest slot is the AGP slot which came before 16xPCI Express.

   The last recommended slot is the PCI slot because there are only a few video cards compatible with it and most of them are the slow, expensive type

4. TV output Capability
   Not all video cards have this capability. Be sure to check this out.
5. Fan
   The fan on the video card must be working to prevent over heating of parts which slows down its performance
6. Price
   How much can you afford to pay?

The compatibility of components determine how the equipment functions. In the case of video cards, there is more need to check for compatibility due to the various models developed to meet various needs.

Incompatibility is expensive, for how will you install a video if it doesn’t fit in the expansion slot?

Unlike viruses, Trojan Horses do not replicate themselves, but they can be just as destructive. One of the most dangerous examples of a Trojan is a program that promises to rid your computer of viruses but instead introduces viruses into your computer.

The Trojan can be tricky. Who hasn’t been online and had an advertisement pop up claiming to be able to rid your computer of some nasty virus? Or, even more frightening, you receive an email that claims to be alerting you to a new virus that can threaten your computer.

The sender promises to quickly eradicate, or protect, your computer from viruses if you simply download their “free”, attached software into your computer.

You may be skeptical but the software looks legitimate and the company sounds reputable. You proceed to take them up on their offer and download the software. In doing so, you have just potentially exposed yourself to a massive headache and your computer to a laundry list of ailments.

When a Trojan is activated, numerous things can happen. Some Trojans are more annoying than malicious. Some of the less annoying Trojans may choose to change your desktop settings or add silly desktop icons.

The more serious Trojans can erase or overwrite data on your computer, corrupt files, spread other malware such as viruses, spy on the user of a computer and secretly report data like browsing habits to other people, log keystrokes to steal information such as passwords and credit card numbers, phish for bank account details (which can be used for criminal activities), and even install a backdoor into your computer system so that they can come and go as they please.

To increase your odds of not encountering a Trojan, follow these guidelines.

• Remain diligent
  Trojans can infect your computer through rogue website, instant messaging, and emails with attachments. Do not download anything into your computer unless you are 100 percent sure of its sender of source.
• Ensure that your operating system is always up to date. If you are using windows operating system, you can go to windows to get some updates.
• Install reliable anti virus software.
  It is also important that you download any updates frequently to catch all new trojan horses, viruses and worms. Be sure that the anti virus program that you choose can also scan emails and files downloaded through internet. If you use yahoo, yahoo will scan the attachment file that you want to download. For safety, after you download scan with your anti virus program.
• Install a firewall
  A firewall is a system that prevents unauthorized use and access to your computer. A firewall is not going to eliminate your computer virus problems, but when used in conjunction with regular operating system updates and reliable anti-virus software, it can provide additional security and protection for your computer.

There is no 100 percent guarantee of your computer security. At least, you can do something to prevent your computer system from malicious software or any destructive program that can harm your computer system.
