The History of Computer Viruses

Computer viruses have a much longer history that most people would imagine. They predate the modern internet although the first viruses were purely technical excises in computer programing. It is not until the advent of large scale internet use that malicious computer viruses started to appear.

The basic theory that underpins most types of PC virus was outlined in John von Nuemans scienfic paper published back in 1966. The work titled “The Theory of Self-Reproducing Automata”. Known as the last of great mathematicians von Nueman had also worked on the US nuclear program and instrumental in developing game theory.

This theory was not used until 1971 when the first ever virus was released across the ARPANET network. The virus called Creeper spread across the network and infected DEC PDP-10 computers. When a computer was infected it displayed a message reading “Im the creeper catch me if you can.” The program was an experiment and the Reaper virus was released to clean up and remove the Creeper.

The first anonymous virus was the Wabbit released in 1974 a self-replicating program that lead to a computer crash. This was followed by ANIMAL in 1975. This virus was attached to a program called PERVADE and it reproduced itself in the background and spread across computers as the program was shared. Although ANIMAL was a non-malicious virus it exploited holes in the OS of the computer and left the name of the Animal selected by PERVADE in all the directories and files that the user had access too.

The Elk Cloner written by 15 year school student Rich Skrenta exploited issue with the Apple II boot system. The virus is widely viewed as the first large scale computer virus in the wild. In the wild referrers the fact that it was not contained with one lab or network.

The virus spread via the boot disk of the computer and every after every 50 infections of the boot disk it displayed a message in the form of a short poem. Skrenta who went onto a successful career in computer programming described Elk Cloner as dumb practical joke.

After the Elk Cloner infected Apple machine virus that infected IBM computers followed. The ARF-ARF virus arrived in 1983 and the Trojan horse wiped out the computers directory by offering to sort it into alphabetical order. Although the Pakistani Flu virus appeared in 1986 it was the following year that saw a rapid increase in the number of computer infections.

In 1987 the Vienna, Lehigh, Jerusalem, SCA and Christmas Tree Exec viruses all first appeared and attacked different aspects of computer operating systems. Other virus occurred in different locations around the globe. These included the Stoned virus in New Zealand, Ping Pong in Italy and the Cascade virus in the IBM offices in Belgium. This explosion in computer attacks resulted in IBM developing its own anti-virus software for the public. Before 1987 IBMs anti-virus software had been for internal use only.

These early computer infections were only the start of the problems created by PC virus. The rate and seriousness of the infections after the end of the 1980s has resulted in the creation of the computer security industry.

A Brief History Lesson About The Computer And How It Has Evolved Through Time

A computer is an electronic machine that has the capability to accept input, store, recall and process information to give an output in a readable format. But in earlier times, a computer meant people performing mechanical computations under the supervision of a mathematician.

In order to understand the future, we have to look at the history. The history of computer systems can be traced back in Babylonia where the abacus was born about 200 centuries ago. The abacus is a wooden frame holding two parallel rods wherein the beads are strung. It was used like a calculating tool by the ancient society. During the year 1642, Blaise Pascal built the first digital computer. He created his calculator to aid his father who was a tax collector at the time. Numbers were entered using dials and it was able to provide an answer as accurately as when calculated by using mathematics. Today, the basic theory of Pascals computer is still getting used in various applications such as odometers and water gauges.

In 1822, an English mathematician going by the name of Charles Babbage was able to develope the very first programmable computer. He had a theory that arithmetic tables could be computed and programmed mechanically. He built a computing machine and called it the difference engine. Babbages difference engines were among the first in its category of mechanical computers. Although his machine was unwieldy, its construction was analogous to a modern computer. It could follow instructions; there was a separate data and program storage, and also it had a detached input and output unit. However, Babbages machine was not really finished because of economic problems as well as a few other issues. You can find a recently constructed version of the difference engine in the Science Museum in London.

The evolution of punched cards provided an important leap towards computing automation. In 1890, Herman Hollerith and James Powers used these cards with computers. They had made improvements on devices that could interpret the data contained in the cards with little intervention from humans. Because of this, work efficiency increased and reading mistakes were greatly reduced. Additionally, these punched cards could be utilized like a storage memory of nearly infinite range.

World War II created a requirement for greater computer power which was to be utilised in military applications. John Eckert and his colleagues in Pennsylvania built a high capacity electronic computer to serve this purpose. This computer was called the Electrical Numerical Integrator and Calculator or ENIAC. It had been an all-purpose computer but of nonflexible construction.

It goes without saying, Alan Turing, Gordon Welchman, Max Newman and Tommy Flowers were key individuals in the development of the computer at Bletchley Park. Colossus was created for code breaking but greatly progressed the advancement of the modern PC as we know it in the present day.

Computer designs from the 50s were mostly valve-driven (vacuum tube). They were much better in performance than their earlier predecessors but they were bulky and expensive to produce. Transistor-driven computers were developed in the 60s which effectively replaced the valve-driven computers. These transistorized computers were faster, smaller in size and more importantly, less expensive.

In the 1970s, the integrated circuit became popular and was widely used as the primary electronic component for computers. It paved the way for mass production of computers, thus making them affordable not only for companies but for personal individuals as well. This led to the birth of personal computers. Since then computer technology has developed exponentially to the point where now we have powerful computers in the palm of our hands. The smart phone, of course! But they still break down, and when that happens we call on an expert IT support service. They might not be able to mend Colossus though…

Today, Computers Are Essential In Almost Everything We Do. We Use Them For Work, For Entertainment,

Today, computers are essential in almost everything we do. We use them for work, for entertainment, for staying connected to friends and family, and more. However, our computers can also get bogged down with a lot of junk picked up from the Internet and sometimes needs a few tweaks to get it running smoothly and quickly again. These tweaks are known as PC optimization, and they can improve your computer’s performance in significant ways.

Benefits of Tweaking Your System

When your computer stops running as smoothly or as quickly as it once did, there can be a number of causes. For example, sometimes programs don’t install correctly or develop problems down the road that cause interference. If you do a lot of downloading or if you’ve deleted large amounts of content from your hard drive, your computer may work noticeably slower because the data has become so fragmented that it takes longer to piece together what you need. Sometimes computers get bogged down with “cookies” and other files from Internet sites which causes them to become sluggish, too. Basically, there are lots of things that can happen when you’re dealing with your computer that can affect performance. The good news is that most of these things can be easily rectified through PC optimization.

Now the Bad News

PC optimization can help correct the problems, but it’s not necessarily something you want to do on your own if you don’t know what you’re doing. For instance, you might need to make changes or corrections to your registry but deleting the wrong file can make programs stop working and can cause major system problems.

Even though you want your system to run as if you just pulled it out of the box, you might end up doing more damage if you begin making changes you don’t fully understand. That’s one of the big risks involved with this type of optimization. Too many people find out the hard way that optimizing their computer is challenging, and they end up doing damage to their computer – damage that sometimes requires completely reformatting the hard drive.

A Solution

One answer is Smart PC ( ), a software program designed to do all of the PC optimization for you. Once you install the program on your computer, you can easily run it and have it make the necessary tweaks and changes you want. The program can fix program files, erase unneeded data or files, boost your Windows program so it runs as smoothly as possible, and can even protect your identity from being stolen by getting rid of personal and financial information that may be left behind after your online transactions.

Smart PC ( ) allows you to do all of the optimization with just a few simple keystrokes. You don’t have to know anything about your computer or about the tweaks being done. The program takes care of all the work and you can reap the benefits, including a faster running system, a better functioning computer, and improved security because your personal information won’t be accessible.

Tips for avoiding computer viruses in your home PC

Those who have had to have a repair service in, such as The PC Hero in the Chicago area, only to discover that the computer issues they have been experiencing have been caused by a virus will all say that while dealing with the repair service has been easy and that the service did a fantastic job, they wish they had avoided the problem in the first place. In order to do so, there are several tips for avoiding computer viruses in your home PC out there.

The best tip one can get is to make sure to have a quality anti-virus program installed on the PC. A company like The PC Hero keeps up to date on the best and most effective programs and can recommend one and install it for clients. One should also inquire as to the best anti-spyware programs that are available. This is something that is needed in conjunction with the anti-virus software that is run on a PC. Furthermore, one should keep these two essential programs up to date, including always downloading updates as they become available in order to be protected from the new threats that emerge daily. For most users, running a daily scan is vital as it is the best way to ensure that any malware that has somehow slipped through the protection that has been set up can be detected and isolated for removal.

A computer user should never click on links of attachments that are included in emails no matter what the source. All of these should be run through an anti-virus scan. It is far wiser to open a new window and to manually navigate to a site rather than clicking on a link in an email, a message or on a social networking site. These are all prime areas where viruses are placed that can do damage to an operating system potentially infecting the rest of a network and even destroying or rendering totally inaccessible data that is stored in ones system.

Users need to be wary of giving personal information, including passwords and login names to those who are phishing or otherwise trying to be deceptive. One should never enter personal information into a page that he or she did not manually arrive at on his or her own. If a page pops up and makes an interesting offer, always check it out by going to the homepage of the supposed host company manually in a new window to determine whether or not an offer or the need for ones personal information is legitimate. Never respond with personal information to any unsolicited email or pop up.

Because it is often deceived by malware, the firewall included with Windows is alone not sufficient enough to offer full protection. One should always have installed a hardware based firewall that is never disabled and that users in the network are fully trained in how to use. This is something that a company like The PC Hero can help with that will be a great asset to either a home based or small to medium business computer network in terms of protection.

No matter how hard one tries there is always some chance that a virus will get into the system. Should this happen to any user, all he or she needs to do is call a company like The PC Hero, one that is competent, service oriented and capable of restoring a computer or network to working status as quickly as possible in order to keep clients wired and their networks and computing capabilities in working order.

Top Tablet Computers – Tips On Choosing A Top Tablet PC

When buying top tablet computers, a few features to look out for include the screen quality, portability, Internet connection, battery, and extras. These features will enable you to choose a top tablet PC that is ideal for your particular needs.

Screen Quality
Setting a screen resolution benchmark of 1280 x 800 PPI will enable you to choose a quality slate PC. A screen resolution of 1280 x 800 PPI or better is recommended, as it will give you sharp pictures. A slate that features in-plane-switching technology is also a good pick because the wider-viewing angle lets you share the screen with others.

A slate PC that is made of Gorilla glass and has a finger print resistant coating is preferable. Gorilla glass is unbreakable and scratch resistant. An example of a top tablet PC that has Gorilla glass is the Kindle Fire.

Portability
Most 7 inch tablets weigh in at between 14 ounces and 15.5 ounces, whereas most 10 inch tablets weigh in at between 21 ounces and 25 ounces. The 7 inch slate PCs are therefore more portable, but as a trade-in you have a smaller display that is ideal for books but not periodicals.

It is also a good idea to check whether a slate PC has readily available accessories like covers and cases before buying, as accessories enhance the portability of your device.

Battery
Most top tablet computers give you more than 7.5 hours of battery life with wireless turned on. When shopping for top tablet PCs therefore, setting a battery life benchmark of 7.5 hours will ensure you purchase a quality slate PC.

Internet Connection
Wi-Fi only Android tablet computers requires you to be near a hotspot in order to connect to the Internet. They are cheaper than those that have 3G by roughly $100.

If you are a power user or a frequent traveler, a 3G version is recommended. However, if you can readily access Wi-Fi hotspots, a Wi-Fi only version is suffice because it gives you similar downlink speeds to that of a 3G tablet.

Extra Features
Most top tablet computers come with build-in speakers as standard, although earbuds are the preferred mode of listening because they give you better quality sound. A slate PC with other extra features like a camera, microphone, ambient light sensor or GPS is worth considering if these features are important to you and they do not overly increase the price of the device.
