Computers have incredible capabilities. They can accomplish great tasks, communicate clearly, make things move and think beyond human measure. Computers have become like humans in nearly every conceivable manner, so it’s no surprise that computers can also get sick.

The computer revolution first began picking up speed in the late 1980s. Since then, it has evolved to be a vital element in our society, our corporate and our personal lives. Computers have become part and parcel to virtually everything we do day in, and day out. But with all good comes a little bad. Some users have maliciously created computer viruses that have grave effects. The range of computer viruses existing in our modern networks has a huge prominence in our lives, because of all the ways we depend on computers. Despite our need for dependable computers, some people have nothing better to do but exercise their computer knowledge in a destructive way, creating computer viruses.

The first computer virus, called “The Brain”, was created in 1986. The Brain is a boot-sector virus, which occupies unused space on the disk to eliminate further use of memory space. After it was created, The Brain quickly spread worldwide in 1987. The Brain virus was considered first to use stealth techniques, making the virus difficult to detect.

On November 1, 1987 another virus appeared. The Lehigh virus was named after Lehigh University, the place where this particular virus was first discovered. One Friday the thirteenth, in December of that same year, the Jerusalem virus was discovered at Hebrew University. This virus has also gone by the names “AabStar”, “Friday the 13th” and the “Black Window”. This is one of the oldest and best-known computer viruses in the world.

Two more viruses surfaced in 1988: the Stone, which was the first bootstrap virus, and the Internet Worm. The Internet Worm caused mayhem in the corporate world as it crossed the United States overnight through a series of computer networks. Then in 1989, the Dark Avenger was introduced. This was a fast-infector that possessed the capability to infect new files despite the presence of anti-virus software. The Dark Avenger computer virus was designed to damage a system slowly. The virus would go unnoticed at first, and damaged files would not be backed up. Slowly it would consume more and more of your computer until it had created permanent damage.

Computer manufacturers and software engineers began the public war against computer viruses around 1990. Corporations began to respond to growing public concern and the number of anti-virus products began to rise. The threat of computer viruses was finally taken seriously. McAfee, IBM, Digital Dispatch and Iris all introduced their anti-virus products and software in 1990. Despite their efforts, computer viruses grew faster, stronger and sneakier. Symantec Norton anti-virus was introduced was introduced in 1991.

The introduction of Windows 95 brought both relief and discomfort to anti-virus companies when it was released in 1995. At that time, most common computer viruses were still boot viruses that worked on DOS, but couldn’t replicate on Windows 95. Then micro viruses were discovered in late 1995. These computer viruses performed in the MS-Word environment, rather than DOS. Again, the anti-virus industry faced challenges to fight against these new batches of viruses. With the introduction and growing popularity of the Internet in the late 1990s, viruses began to spread at a much faster rate.

Throughout 1998 there was no lessening of computer virus attacks MS Office, MS Windows, MS Office and network applications. New viruses continued to appear, and computers and advanced network-to-do applications continued to be affected. In 1999, another virus appeared, infecting computers using Microsoft Word. This computer virus may have been passed on via MS Outlook, or through Outlook Express e-mail programs.

As long as we continue to use the Internet and share computer files, we are at risk of catching computer viruses. Even today, more and more viruses are still being discovered, leading to big problems for all users, and creating ongoing dilemmas for the creators of anti-virus programs.

Like people, getting sick is an unfortunate fact of life for computers. Using up-to-date anti-virus software is a sort of preventative medicine, helping to keep computers healthy and computer viruses at bay.

Windows Vs. Mac OS – Unbiased Comparison Between Two Big Systems

While there are a bunch of different brands of computers to choose from, there are only two real operating systems the average user can choose between: Windows and Mac OS. Linux is also out there, but that is usually only chosen by people with advanced computer skills or businesses. When you have to buy your next computer you will be well served to look closely at what both Mac and Windows can offer you and we are going to be checking out some of the respective advantages offered by both in this article.

For anyone concerned about security, the best choice is not Windows. If you are a Windows user, then you already know about computer viruses. Part of this is due to way more people using Windows, but Mac users are also less vulnerable, for some reason. The things are just as true for malware and spyware. If you choose to get a Windows OS, then it means that you will be needing to have anti-virus software that always needs to be updated, which will cost you time and money. No matter what kind of computer you have, threats are real and precautions should be take, but there are less concerns with a Mac. When you reveal your own data to a scam artist or hacker, you are causing security issues by your own actions, and you should always remember that. So you have to use common sense no matter what kind of computer you’re using.

If you follow tech news, you might be hearing quite a lot about Windows 8, which is the next important upgrade to the Windows OS. For some, this might make a difference in the whole Windows vs Mac debate, as with this new release, Windows is going to be introducing some radical new features. Most importantly, Windows 8 will give you the option of using your computer as a tablet, with a highly functional touchscreen. You’ll also have the option to use a traditional mouse or keyboard. Of course, as of this writing, Windows 8 has not yet been released. The earliest release date we can find is sometime in 2012. And by the time that date rolls around, Mac will have developed something to give it a run for its money.

If you regularly use computers at school or at work, it’s very likely that they are going to be running the Windows OS. If this is true for you, then selecting a Windows based computer for your home computer is the smart thing to do and the more convenient thing to do because you can be sure that you have all of the same programs downloaded. For one thing, it can be hard to share files with PC users if you’re on a Mac. It’s easier than it has ever been to move between Macs and PCs because there is more software compatibility than ever and because if you have a Mac you can use Bootcamp to help your computer run like a Windows based PC. Of course, if you primarily work with programs and files that are Windows based, there isn’t going to be any advantage to choosing a Mac. Macs are more popular than they have ever been, but the truth is that most schools and corporations and major organizations employ Windows.

You are better qualified to decide on either a Mac or Windows, because you know some of the differences in the two operating systems. A Mac or a reasonably good PC will serve your needs for most tasks you will do each day, such as watching videos, chatting, running typical programs, and whatever else. After all of your research, you should limit your choices to several computers, any one of which will work for you, and then choose the one that you like best or has the best price.

Buying a printer that is easy to work with is one of the ways that you can make your life easier when looking for replacement cartridges.
