When browsing online it can be difficult to know how safe and secure your computer really is. There are a lot of malicious websites on the Internet, and stumbling across just one of them can be extremely harmful if you haven’t taken some steps to protect your computer. A common misconception when securing your files is that it is either too hard or too expensive – neither of which are true. You don’t need to be an expert in IT to take a few basic steps to ensure your computer is that little bit more secure.Here are 5 top tips to protect your computer online:1. Internet Browser – If you are using a Windows PC then by default you may be using Internet Explorer to browse the Internet. This browser has been upgraded to be more secure, but it still contains a lot of vulnerabilities – especially the older versions. Try using one of the newer browsers such as Mozilla Firefox or Google Chrome. Upgrading your Internet browser is beneficial for security.2. OS Updates – With any operating system there will be certain issues that can be improved upon. When a new operating system is released it is only a matter of time before a flaw has been found, and the companies work fast to release updates to prevent this. Keep your computer up to date with the latest operating system updates to ensure your computer is fully prepared.3. Antivirus – Having a good antivirus installed can be critical to protecting your computer online. No matter how secure you are, without an antivirus you are still very vulnerable. It is better to pay for antivirus software, but you can still get good ones for cheap, such as AVG. Before browsing on the Internet you should install an antivirus that will help prevent your computer from being infected with any malicious content.4. Firewall – Similar to an antivirus, a firewall helps to protect your computer from harmful content. A firewall is useful to block programs accessing the Internet without consent, and works well to spot potential issues while on the web. Some firewalls are available for free, but you can use the built in one if you are on a Windows machine.5. Don’t Be Fooled – Now although this isn’t a tip as such, it is probably the most important security prevention you can take. When browsing the Internet, be careful what websites you go on and what files you download. Avoid installing toolbar addons for your Internet browser or downloading programs for your computer unless you know they are secure. Malware and spyware is a very big issue online, so do your best to prevent it by sticking to trusted websites.The above tips to protect your computer online and just some of the preventions you can take when using the Internet. By keeping your computer secure you are also keeping your files and identity safe – so it is your best interest to take a couple of steps to protect your computer.
The internet has ushered in a new way for companies and customers to do business. Where it once was considered rare to order a product online, it has now become the norm. The computer industry is made up of many quality companies that all offer their products online. But if you are in the market for a desktop computer, how can you be sure that you are making the right decision? In this article, we’ll simplify the process so that you know how to buy a desktop computer online.The good news in buying desktop computers today is that you are able to get a lot of capabilities at a very affordable price. It wasn’t too long ago that desktop computers would cost thousands of dollars, but that is no longer the case. Now, you are able to receive a high quality desktop computer for as low as $500, sometimes even lower. Now that you know price won’t play too much of a factor, the first determination you have to make when buying a desktop computer online is what you intend to use the system for.If you are planning on buying a computer for basic tasks such as word processing and surfing the internet, there is really no need to buy an expensive model. Most basic desktop computers offer 512MB RAM (memory), and this should be more than enough to serve your needs. With that being said, it is best to buy a desktop computer with atleast 1GB of RAM, because you may need it later on down the road. While you might pay a few extra dollars for the memory, it is well worth it.However, if you plan on using the computer for optimized gaming and video, you will definitely need to boost the quality of your system. Most of these higher-end desktop computers still cost less than $1000, and these babies can fly. If you are the type of person who doesn’t like to wait, then it is all about the processor. If you are ultra-serious about your gaming and video, you would be best served to buy a computer with a dual -core processor. Dual core processors allow for insanely fast multi-tasking, and are perfect for those people who have the need for speed. Intel makes several of these processors (4, D, and Extreme Edition being a few) as does Athlon (64 X2).Frankly, the rest of the details regarding the desktop computer are of lesser importance, and they should be more than adequate depending upon your individual needs. One final note regarding your computer choice – it is recommended you buy an extra warranty. This could save you big money if something should go wrong with the computer down the line.Now, let’s turn our attention towards the actual purchasing of the computer. It is vital that you choose the company wisely, and the best way is by doing an adequate amount of research. Most high-end companies (Dell, Gateway, HP) have products that can be trusted, but that’s not to say you should limit your thinking to only the major players. There are many quality computer companies out there that may be flying under the radar.When placing an order online, it is important to protect your personal information at all times. It is best to only do business with companies that offer a secure server at the online checkout. There are several encryption services (VeriSign being one) that will make sure your personal information stays safe. Make sure the web site you order from has such a measure in place.Hopefully, these tips on how to buy a desktop computer online will help you make the right choice based on your individual needs. Remember to get a desktop computer that has all the features you need, and do your homework before actually turning over your payment information. Good luck!

There is no self-cleaning smart tool in a desktop, in fact, the very algorithm and design of hard disks, memory and any form of optical storage is indiscriminatory in that it does not deem which is useless junk and which isn’t. Data is data, and the machine is not reflexive nor does it have the faculties for self-determination. It will organise them in a way that makes most sense and utilise the space the most efficient way. This is not cleaning up the computer, merely reorganising to use up whatever space you have. But even your desktop needs to breathe and after a while, all the unwanted junk will become giant invaders of speed. Here I will teach you how to clean up computer – eliminating all the unwanted junk that you really don’t need anymore.Programs come with their own baggage and how they are written, coded and executed will depend on how much of this debris they leave behind in your desktop. From temporary files, system files strewn about, unwanted DLL’s to free floating unknown extensions thrown about your hard disk’s memory banks just as almost an afterthought, there are countless ways in which these software can choke up your system. What’s worse is finding out that there are programs running in the background you had no idea about, eating up precious memory and slowing down the PC even more.

Just do a scheduled maintenance, check occasionally the integrity of your computers memory banks, and clean up the clutter!Malware, spyware and adware. Be ‘aware’ of these things and you’ll realise my whimsical sentence makes more sense than just annoying you. I consider cookies a form of spyware because after a while, and left to their own doings, they will choke up your surfing experience. Adware and spyware install all sorts of junk in your computer, from discarded bite sized pieces to car-sized behemoths that launch background applications and try to use your PC as a money-generating machine – without you being aware of it. Ever had your browser lock up, invaded by pop ups, taskbars you never knew came with I.E or new fangled advertisements telling you that you need a ‘bigger package’, regardless of your gender? Then you have been invaded by insidious worms of programs that crawl and leave their dirty digital footprints all over the place. Get an anti spyware program! Get an antivirus! It will do you good!My last piece of advice to you is to get a good registry cleaner and optimiser. I will akin the registry to a matrix of elevators in an extremely busy office complex.
