The Internet is a very dangerous place. If you aren't careful where you're browsing, it is very easy for your computer get infected with a malicious virus. Sometimes, you have to click on a link or actually install something to get a virus, but in other cases viruses can infect your computer as soon as you browse a website. On top of that, if you regularly download files through peer-to-peer networks, then your chances of getting infected increase exponentially. Here are some tips on how to know when you're infected, and how to remove the viruses.
A viral infection can take a number of different forms and show many different types of symptoms. You might start suddenly getting popup advertisements, even when you're not actually browsing a website. Or you might notice that your computer just seems to be performing very sluggishly. With the most malicious types of viruses, your computer may stop working altogether. But perhaps the most dangerous types are the ones that run subtly and steal your account names, numbers and passwords in order to steal your identity.
For the more subtle types of infections, it can be hard to determine if a virus is really the cause. In other cases, even if your computer shows symptoms of viral infection (such as general slowdown), it may not be viruses that are the cause. Since it can be tough to know for sure if your computer is infected, and it can be catastrophic if you don't detect and remove an infection, the best thing to do is to scan your machine regularly. In order for that to be successful, you must also make sure your virus scanning software is up to date and has the ability to detect the most recent viruses out there.
There are a number of free virus and spyware scanning programs out there on the Internet. While most of them are quite thorough, not one program is a catchall, so you may want to run two or three different scanning programs just to be absolutely safe. If you don't already have a virus-scanning program, then you should download one straightaway and install it. Unfortunately, some viruses are very crafty and will actually prevent you from running install programs for virus scanners that can find them. In some cases, you can simply trick the virus program by renaming the installer program for the virus scanner.
Even if you are able to successfully scan and remove viruses, you may find that they come right back the next time you start up your computer. If that happens, then you may have a virus with a rootkit component. Rootkits basically make it so that as soon as your computer is restarted, the virus is reinstalled. Many basic virus scanners can't get rid of rootkits, but there are other free software packages specifically designed to battle rootkits that should work.
If you still have problems, then your best bet is to seek out one of the many online forums that specialize in helping people fight viruses. Volunteers on these forums will walk you thorugh step-by-step to help you cleanse your compute of viruses.

For many business owners, computer hardware is something shrouded in mystery. They know they need it, but they aren't really sure what they're getting when they buy it.
According to a recent article on alibaba.com, this lack of understanding causes many businesses - especially small to medium enterprises - to buy more than what they need. Overbuying causes more problems than you might think. Fortunately, it is easily avoided by gaining a basic understanding of your computer hardware needs and shopping more wisely.
Understanding How Much Computer Power You Need
One of the biggest dangers in overbuying is, obviously, that you are overspending. Do you need the Intel Core 2 Duo P9600 chip, or can you manage with the P8400? Is 2 GB of RAM enough or do you need 4GB? Can you buy a machine with less installed memory and an expansion slot for future upgrades? Are there other features you can live without for now and add on later?
These are all questions you should be asking yourself before you buy any equipment. Take a long hard look at the specs on a machine, and try to gauge whether you really need them. A huge hard drive on a desktop might seem like a good idea, but if you have a network, do you really need it?
If you are uncertain how to read specs, do some research. There are some excellent guides to buying computer hardware, and also some very good glossaries that explain what all those acronyms mean. Some glossaries can be very technical, but about.com has one that informs without confusing.
Why Buy Hardware That Will Be Obsolete in Two Years?
As the alibaba.com article notes, obsolescence is another pitfall of overbuying. The hardware life cycle is two years or less. In other words, the manufacturer you buy from today will have a fancy new machine available within two years, if not sooner. Some experts even peg the hardware turnover cycle at 9-12 months.
Buying the latest and greatest often means you will lay out a lot of cash for features you don't really need that may be obsolete within months. Matt Siegel of Little Tree Networks was quoted in the alibaba article as saying that most new small and medium businesses spend two to three times what they need to on hardware and software. He suggests buying off-lease or refurbished PCs to save money.
Indeed, there are vendors out there who work directly with manufacturers and large companies to secure inventories of off-lease and refurbished computer hardware. IBM, Lenovo, and Toshiba are just a few of the companies that have such an arrangement. These "older" machines are a fraction of the price of new ones, and have specs that meet or often exceed the needs of most small businesses.
Resellers also offer components so businesses that buy older equipment can continue to upgrade it and service it, even when parts aren't available on the "primary" computer market.
When it comes to computer hardware, overbuying is a costly mistake. To avoid falling into the trap of obtaining too much computing power, do your research, understand your needs and shop smartly on the used computer market
Remember the times that you planned to buy a computer or a laptop and called the tech-support of a computer manufacturer to discuss your options and got bombarded with a number of questions; all technical mumbo jumbo? Well, many of us have faced that and have steered away from buying a computer thinking it's just too complex!
Let's look at the basic steps that one should follow while planning to buy a computer:
Step 1: Why do you need the computer for?
To maintain your finances?
To help your kid with his/her homework?
To stay connected with the world?
To play games?
To help in your business?
Your answer to the above will help decide the type of computer that your need and the specifications the processor, the memory, the hard disc, the type of keyboard, the number of USB ports, etc. etc. A tip is to always go for a bigger memory which will help you later when you want to add more software to your computer and faster processor which will help your computer stay on its toes even if you have a number of programs running simultaneously.
Step 2: Remember budgeting is very important. The specifications will give you a rough idea on the kind of budget you should settle for.
Step 3: Once you have decided on the computer specifications and the budget, you must look around. Always compare the prices and the options that you get from various manufacturers. These days you get great online resources and websites that will give you comparison results in tabular formats to find which manufacturer is better. A tip could be to stick to the better known brands. These will have good service centers and easy access to customer service. These generally have a proven track around. You can also choose to ask your friends and family on their choices.
Step 4: Do not get confused or overwhelmed by the list of options and types of computers available these days! Stick to your step 1 and your specifications. Although different options may look lucrative, but do not end up paying for features that you may hardly use. If you want a simple computer a plain CPU, monitor, keyboard and mouse then so be it. Stick to it.
Step 5: Finally decide on a shop and go for it. You can choose from online stores or actual stores with displayed merchandise. If you are in doubt then choose a store where you can just walk in, discuss your requirements with a sales person and decide on your computer. If you are relevantly confident about your requirements then go for an online store. Most online stores offer great discounts.

The Acer Black AX1430G-UW30P Desktop PC Could Be A Good Option For People That Are Looking To Get Themselves A New Computer
Even though some individuals may believe that desktop computers are becoming obsolete due to all of the laptops, there are still people who prefer a desktop. Although laptop computers can be extremely convenient because you can bring them together with you wherever you go you're going to see that they wind up breaking much easier than a desktop computer. One of the other reasons individuals prefer desktops is mainly because the computer screen can end up being much bigger than anything you might get with a traditional laptop. The Acer Black AX1430G-UW30P Desktop PC will be what we're looking at in this post because of its features and the affordability of the product.
The hard drive which comes with this computer is in fact 1 TB which is actually a great size for any kind of computer on the market today. A few in years past most computers that were being launched carried a 160 or less gigabyte hard drive, I just wanted to point that out so you realize how large this hard drive really is. I am sure you are going to also be impressed with the fact that this computer includes 4 GB of ram, which is something which is great for gamers and folks who multitask.
The Windows 7 home premium edition is actually the platform which comes preinstalled on this computer which is the very best windows that has been released recently. This is obviously windows latest platform, and based on folks who have used this platform it's a large improvement over their previous platform.
Yet another great thing you are going to find relating to this package is that it actually includes a 21.5 inch wide screen monitor. A primary reason it is great that they include a monitor with this computer would be that a monitor of this size could wind up costing you over $200 if you had to purchase it separately. Something else worth mentioning relating to this computer monitor which comes with this package would be the fact that the speakers are actually built into the monitor.
The DVD burner which comes together with this computer won't only burn DVD's but you are going to also have the ability to burn audio CDs and also data CDs. Something which plenty of people are going to like about this computer apart from the reality that it includes 6 USB ports would be that it has an HDMI port also included.
Because this is actually a fairly new product you're going to discover that there are not plenty of reviews around of course, if you check on Amazon you'll see that there are no reviews yet. If you wonder how much this entire computer packages going to cost you are going to discover that you are able to actually buy it directly from Amazon for about $550. I ought to mention that this is really $100 off the suggested retail price you would need to pay for this item elsewhere. There are lots of desktop computers readily available but not all that have the attributes that this computer has, which makes this a good option for men and women looking to upgrade their computer.
What is a transparent computer casing and what could it do for you? Well, before we start talking about the clear computer housing, allow me to inquire you something: what does your computer's case signify to you? I can even inquire: what does your computer signify to you? I inquire this as your answer will ascertain what you would like for your computer and its housing or case.
Most people have always been happy enough with the plain, standard light-grey housing that comes as bog-standard with the preponderance of computers. Some have never even thought about it. But then there are others who have thought about their computer?s case a lot and who would like something special for their computer.
Some of these people were accomplished at metalwork, others at woodwork and a few at glassware and there are a few truly incredible, innovative, homemade cases out there. Especially among the gaming community. However, we are not all so able with our hands, but that does not signify that we have to be stuck with a grey computer case.
The easiest choice, if you want a custom computer casing is to construct one out of acrylic - the sort of substance used to construct the majority of fish tanks. You can buy and easily cut sheets of acrylic for the sides and bond them all together with acrylic resin. That may appear tricky, but it truly is not. In the beginning you would have to research the architecture of a normal computer case and then just copy it in acrylic. You can construct a clear computer casing in a weekend.
Or you can buy a clear computer casing kit. These kits arrive in flat-packs just like most kitchen fittings and can be easily assembled according to the instructions with a screwdriver. No cutting, no measuring, just a little gentle screwing.
And I signify gentle, because the screws that come with the see-through computer case packs are usually made of acrylic too and will break easily. It is the only part of the assembly process that requires a admonitory note, for the reason that you don?t want to have to drill out a broken screw, do you? That would only put a downer on your fun.
So why would anyone want a translucent computer case? I think that there are loads of explanations. Some individuals may just want to be different and others may want to show that they can assemble or even create such a housing. However, the clear computer casing also has aesthetic and practical advantages. At least the good ones do.
On the Aesthetic Front: enthusiasts add neon lights and small LEDs that twinkle on and off or just glow eerily, possibly activated by some incident, like a hard drive coming to life. These displays are called ?themes? and are normally red or blue, but can be almost any conceivable colour. Then you can include coloured fans (or paint your existing ones). You already have at least one fan in your casing and probably two or three.
On the Practical Front: loads of individuals like to see what is happening inside their computer case and it is neither practical nor safe to remove the cover all together. Furthermore, assembling your own transparent computer casing allows you to insert more fans as over-heating is the foremost cause of hardware failure. The more fans the better.
A transparent computer casing would also allow you to observe whether a fan has failed, which would result in over-heating in a normal housing and certain hardware malfunction, whereas you would see it happening through your clear computer case and replace the fan before serious injury and loss of data can occur.
