Computer Viruses and Spyware

Types of Computer Viruses

There are many different types of computer viruses and understanding the differences is the first step in protecting your computer. Among the worst viruses are the kind that will corrupt the data on your hard disk which can render your computer useless and require a technician to re-install the operating system. Other viruses can run special routines that try and overhead your chipset and actually create permanent damage to your hardware. Most anti-virus programs are designed well enough to catch and eliminate the most malicious viruses and thus the viruses you see sneak by will be more subtle. One of the more recent and clever viruses falls under the category of what is called a "rouge anti-virus program" which essentially pretends to be a legitimate anti-virus program, informs you of a virus on your computer, and then asks you to "upgrade" your software for a fee to eliminate the virus. Often times these programs will try and collect your credit card number, and upon receiving it will disappear leaving the user thinking they have purchased something legitimate. The rogue anti-virus programs are often designed to look and feel just like real anti-virus programs and is thus deceiving to the computer user. The program will typically prevent you from running any programs or accessing files until you "purchase" the software from them by giving them your credit card number. As should be readily apparent now, one should never give out their credit card number to a program that blocks you from using the computer.

A very common feature of viruses is to capture your email password and then send a copy of itself to your contacts. Since your email contacts know you, they are likely to open the email and click on the attachment which will then infect their system. If you believe that emails are going out of your account and you aren't the one sending them, immediately change your password.

Types of Spyware

Spyware is typically less harmful and malicious than a typical computer virus, but it can still affect your computer's performance and expose your personal information to unauthorized third parties. spyware is typically lumped in with what is called "adware" which are annoying computer programs that display advertisements on your screen. The two often work together whereby the spying program collects information about what websites you visit, the articles you read, the things you purchase, etc and the advertisement program shows you related ads. Legitimate companies will sometimes purchase advertising packages from adware companies to get their product to pop up on your screen. Sometimes this type of advertising software is installed on your computer when you download free programs, and the idea is that you will see advertisements in exchange for using the free software. It may sound strange at first, but this is the same model that television stations have been using for decades.

Motivations Behind Computer Viruses

A lot of people ask why computer viruses are created in the first place. The most obvious reasons would include stealing money through credit card number, identity theft, or any other way a person could profit from it. People also create viruses out of sheer vanity, or in other words to just prove it can be done and see the impact you can have on larger organizations for a short time. Sometimes computer viruses are created to target a specific organization and take down its network or disable some function of that organization. So much of the world is now run with computers running some sort of Internet application that if one can disable this they can disable an organization. From an international perspective there is the concept of "cyber-warfare" where countries employ computer experts to either hack into computer systems or target viruses to other countries or organizations within that country.

Free Anti-virus Programs

There are many legitimate paid-for programs on the market and a typical computer user should have no problem finding a retailer willing to sell them one. Most people don't realize, however, that there are excellent free anti-virus programs that work as well as any program you would pay for. These free programs will often have a base set of features that are offered for free, and then advanced features that you can pay for. Two of the most highly rated and widely used free anti-virus programs are Avast and AVG. Each has an excellent free anti-virus package available for free and both offers increased functionality for a small fee.

Fix Windows Computer Errors Fast

Overheating: For a CPU that is overheating, you may check the PC health section of your BIOS. A healthy CPU fan generally runs at about 3000 to 5000 RPMS. You may also want to check your power supply and video card fan. A fan may be repaired by cleaning it (removing and unclogging dirt on its blades).

Computer memory: Widows usually detects a problem with your computer's memory and may start the memory diagnostics tool automatically. However, if you suspect that there is a problem with your memory and wish to start diagnostics manually, go to the memory diagnostic tool, which is under, Control Panel>System and Maintenance> Administrative tools. You will be prompted to choose whether to run the program on restart or restart and run later.

Errors on your Hard Drive: To check for errors on your Hard Drive, go to My computer, right click on the drive, and click Properties>Tools and then click Check Now...You may choose automatically Fix file system errors for a more thorough scan.

Outdated or poorly programmed device drivers: When your computer seems to predictably crash when you perform certain tasks such as play games, watch movies or plug-in certain hardware such as a joystick, the drivers associated to that task may have a problem. The first thing is to check for compatibility. Check if the drivers you installed meant for your version of windows.

Corrupt files and programs: Corrupt files may also present problems in your system. A corrupt file is sometimes created when there is interruption when you try to

The quickest way to find a problem is to always start with the most obvious cause. Generally speaking, hardware malfunctions are usually the most obvious and easiest to Fix. Secondly, check if there is a pattern for the "crashes", especially if you have encountered several "crashes" before. For example, you may find that your computer tends to crash when you are watching movies; this may indicate a problem with your graphics card drivers.

What causes a computer crash?

A computer crash is a condition where a computer's application and or operating system ceases to function properly and exists, due to a malfunction in the execution of the machine instruction. The most commonly known computer crash is arguably the "Blue Screen of Death". These crashes sometimes happen at the least convenient time, like when you are about to finish an assignment or report, not to mention the time wasted when you try to restore the system.

Home Theaters Computer Integration

It used to be that computers were merely used for office purposes, accounting and payroll, documentation, and the like. Nowadays computers have reached a phenomenal audience and service than ever before. It is a fact that personal computers are being used as vital elements in home theaters currently. Design of operating systems has evolved alongside the development of personal computers as well. It circles around the idea that it can be utilized as an effective media center by way of integration into the home theater components such as a receiver like the Onkyo TXNR708.

There will be an increase in growth in the utilization of computers because of this usage. With a lot of people integrating the use of computers in diverse parts of their lives, it is but natural that the bridge to entertainment integration is crossed. The integration is not that new. The increasing number of individuals using the technology is what makes the difference.

These media center PCs are systems that in essence function as a receiver would normally would. They take in the needed data and network it to the connecting components in the system. You will be able to watch DVDs, listen to music, and so on. It is also possible to view movies through your computer monitor rather than your television screen. With this use, you can even record and store your favorite shows or movies in your hard drive. Another benefit is that you can create photo slideshows with the wonderful still memories you have in your storage.

If you were to have suggested that your computer would be an innovative system that can run your home theaters a few decades back, you would have been laughed at. In this generation, the idea is not only accepted and practiced but a lot of people and businesses are thriving because of that very technology. It is also a technology that people spend on developing as it is evolving to be one of the increasing demands in the market of home theaters.

Increasing your personal entertainment and enjoyment is not an impulse result. You should take your time to educate yourself on the usage of new technologies so that you can achieve its full potential. It will prove to be the foundation of superior things in the near future for your home theater. As all commodities evolve and advance, it is possible that we will see innovative development of functionality when it comes to home media center PCs. This will also involve bringing in additional features and expansion of current capacities.

There is nothing more advance than having your home media center integrated with your computer at the home entertainment arena.

Today, it is best to check out what the combination of computer and home theater can do for you if you haven't taken it to consideration yet. The additional boost of functions and capabilities of the integration will sure to prove very useful and entertaining for you and your family. As you take your time to do so, kindly check out the new developments for each arena- computer and home theater- as there are innovations like that from an Onkyo TX-NR708 Receiver that may supplement each when you think about purchasing or upgrading systems in the future.

How to Make Your Slow Computer Go Faster

Are you sick and tired of your computer running so slow, and wondering how can I make my computer faster?

This is a rampant problem, and you're by far not the only person looking for a faster computer. Most people absolutely love how quickly they can shoot from one program or website to another when they're computer is brand new.

However over time, your computer begins to get slower and slower. Starting up your computer becomes a whole process.so much so that you hardly even shut it down anymore because you know it will take forever to restart. You may even start to avoid using certain programs because you know that you'll be sitting there waiting for it to load up for so long.

Usually when you're sitting there in irritation wondering how in the heck I speed up my PC, your first thoughts probably turn toward viruses or spyware. This is normally what people think of first when they're computer starts to act up with things like their computer freezing up, crashing out, or like mentioned before having to enduring slow start ups. This is actually a genuine concern, because viruses, spyware, and malware can cause a ton of trouble for you.

But more often than not, the problem is a registry clog up rather than a virus. Good news of course, but this can still be disheartening and annoying!

What Causes This to Happen?

You see, your computer registry (actually Windows Registry) can be thought of as basically the hub for activity on your computer. I guess you could say it's sort of like the brain of your Windows System, which tells all of the hardware, programs, and settings (the nervous system if you will) what to do and when to do it.

It's an essential part of your operating system, and is what actually helps everything run smoothly, but every now and then something in that nerve center goes awry and just like your body, your computer begins to have little twitches, starts slowing down considerably, and sometimes just crashes altogether. Most often it's because of an error in the registry.

Things that cause errors are:

Installing or removing software or programs
Shutting your computer off incorrectly (or during power outages)
Changes in the control panel
Corrupt files left behind from viruses and Trojans, even after cleaned.

You need to clean these errors out of the system, and that will make internet faster, as well as make your computer faster overall.

You Have to Clean Out the Junk!

Just as well, your computer can end up with a ton of junk files, and temporary files. This is normal and simply occurs overtime because you surf the internet, delete programs, etc. Having these files clogging up your hard drive will definitely cause you to ask how can I make my computer faster.because the effect of these files is simply a slower machine.

Once these registry errors are fixed, junk files are deleted and history and cookies are eliminated, you'll see that your computer is running almost like new again. So now the question is. "How do I clean my registry and speed up my computer?"

How Do I Speed Up My PC and Clean My Registry?

So while Windows is extremely user friendly in some sense of the word, it's not all that easy to fix when something goes wrong. When things like your registry goes haywire, you have to nearly have to have a degree in computer science to even begin to find out where the problem is.

Thankfully there are software programs out there that find and fix the problem for you.

There are registry cleaners all across the internet that claim that they can make internet faster, make Windows XP faster, and help all those people in general who just want a faster computer.

But Will They Work and Give Me a faster computer?

The fact is just like everything else, some are better than others and some are outright scams. In other words it's very easy to waste your money, especially if you're nearly in tears and almost pleading how can I make my computer faster now? Of course these products feed on desperate buyers who need a fast solution.

After testing tons of different registry cleaners and realizing that more often than not they didn't work, or you needed to be a genius to figure out how to use them.I found the one that I've used over and over again ever since finding it and I haven't looked back.

It's called Registry Easy and it's made for people like me. People who just want an easy solution that works, and works fast.

Registry Easy does a myriad of things that will make your computer run faster, eliminating your problems from different angles. It will:

Scan and Clean Your computer - From a drop dead simple to use interface, with just a couple clicks of the mouse, Registry Easy will scan, locate, and list of all the problems that is affecting the way your computer is running. This will allow you to fix the problems either automatically or manually basically with a click of the button.

Create Backups for You - You always want to create backup points when doing a registry clean, just in case anything goes wrong. This is a daunting process if done on your own, but Registry Easy does it for you giving you piece of mind. It'll give you a Registry Backup, Restore Point, Favorites Backup and Folder.

Give you Timely Customer Support - Most software companies leave you on your own once you've bought their product, but not Registry Easy. They're there to help you because they want you to be successful with their product, and that clearly shows. They answer promptly and get you up and running with clear instructions.

Give You Safer and Easier to Use System Tools - Registry Easy gives you 6 different system tools that are essential to keeping your computer running smoothly such as Block ActiveX (blocks malicious controls), File Recovery (easily recover important files), Password Recovery, Start Up Manager (gives you much more control of start up applications allowing a faster start up consistently)

Listen, there's nothing more aggravating than a computer that's not running optimally, especially when you've got important things to be done. After trying most of the major registry cleaners on the market, I've yet to find one as consistently powerful and easy to use as Registry Easy. It stays fast!

7 Tips to Consider When Buying an Inexpensive Notebook Computer

Buying a new inexpensive notebook computer can sometimes be a real challenge. There are so many things you have to consider. You have to make sure you get the best deal for the price that you pay. Also make sure you're not ripped off or overpay for any of the features. This is why I have seven tips and tricks for you to implement when you're buying a new inexpensive notebook computer.

1. Make sure that you don't opt in for the five-year guarantee- yet always seemed like a good option because they say that they will protect your computer if anything happens. This can be useful but most computers can usually go about for years without getting damaged. And as for the five-year guarantee, most people will get tired of their computers in about three years and they will want the latest and greatest technology. So all in all there really is no need for a five-year guarantee. It is just an extra cost and you may never even need it.

2. Ports- Only buy the ones you need. Usually for most people, the only important ones are HDMI, SD card ports and USB. If you go for more than that, they usually cost more money. You may end up paying money for ports you don't even need.

3. Don't fall for the latest and greatest items. They may seem great but they usually way overpriced. For example the older version might be up to $300 cheaper than the new version. Yes I agree the new versions are all cool, but why not stick to the older version and save money, when that's all you really need.

4. Check out the battery life. If the battery life is not all that great and the laptop is very expensive, you know that that is not a good buy. Picture the battery life is good and seems about right for the price.

5. Try to avoid additional accessories when buying an inexpensive notebook computer. Sometimes they will ask you to buy additional mouses or may be WebCam accessories. However most of the time they are not necessary. So if you want inexpensive notebook computers make sure they don't fall for these tricks and end up paying more than you should.

6. Screen Size- You don't need a enormous screen size. Usually up to 15 inches is good enough. Actually in some states, there Is an extra charge for inexpensive notebook computers that are over 15.6 inches. But if that is something you need, by all means, go ahead.

7. Stick to the basic versions. Don't fall for the icing on the cake. If there is an option between Windows home professional and Windows ultimate and the pricing is $200 apart, you should go for the Windows home professional. If you really feel like you'd need Windows ultimate, then buy it separately. Don't pay $200 extra for already installed software.

If you follow those seven tips and tricks, it is a given that you will end up paying much less for your inexpensive notebook computer. Actually, you will be putting money back into your pocket.
