Antivirus Internet Security Basics: How Viruses Get on a Computer

Recently a computer security expert stated that the only way to keep a computer 100% safe was to never turn it on. It turns out this inaccurate and a little misleading. A computer used solely to type up and print out documents, never connected to the Internet and that never received files transferred from some other computer, could in fact be a useful 100% secure computer system. This brings us to the two main ways viruses and other malware get on a computer: through a network like the Internet and file transfers from other computers.

Users want to attach computers to the Internet and receive emails, instant messages; browse web pages, download music and fun software etc. The problem is that this puts not just millions but billions of people at their doorstep! Imagine that if billions of people could reach a home instantly – how many ill intentioned people would come by to see if the doors and windows were secured? How many con artists would knock on the door? An Internet connected computer is in just that predicament.

When a computer is connected to a network by design it starts listening for communications from the outside world. Things known as ports get created which are special “doors” to the computer. These doors are special because they each have a designated program that will answer the door if it is knocked on. Examples of programs that listen for traffic from the network include:

1. instant messaging programs
2. Internet phone software
3. software for connecting to the computer from remote locations
4. Internet games
Even the operating system itself opens ports to share files or a printer or anything else on the computer. Each of those programs creates a “door” to a computer that it will answer if someone “knocks” on it. If that program is poorly designed then when it answers the “knocking” program could take advantage of it and thus compromise the computer.

In addition to people being able to come across the Internet and knock on one of the “doors” mentioned above – by using a web browser and surfing the Internet users are inviting people to access their computers. Every time a web site is browsed the web browser is downloading files to the computer and processing them. If that web browser is not programmed properly it is a huge security risk. For example on December 12 of 2008 Microsoft reported a big security hole in all versions of its Internet Explorer browser. The hole permitted data stealing software to be installed on the victim’s computer just by browsing an infected web page! Other examples of programs that invite access to your computer:

– Email programs
– File sharing and music sharing programs (by far one of the largest security risks)
– Instant messaging software
So aside from isolating a computer from the outside worldHealth Fitness Articles, how can one protect a computer system? Here are some tips:

1. Don’t use Internet Explorer as your main browser. I am not bashing Microsoft or Internet Explorer particularly and something should be made clear: It is not necessarily that other browsers are programmed so much better but that 80% of people surfing the Internet are using Internet Explorer. Thus thieves interested in gaining access to the maximum amount of victims are going to spend most of their efforts exploiting the security holes of the browser that 80% of the people are using.
2. Put a firewall between your internal network and the Internet. A firewall’s job is to keep out those billions of people who can be at your doorstep instantaneously. It will only allow those you invite to knock on your computer’s door.
3. Use a Firewall on each individual computer. The network firewall mentioned above is a big step toward protecting the internal network. The problem is that it generally won’t protect users from themselves. A user browsing a website is telling the network firewall that it has given an invitation to that website and to permit files from that site to come through. If the user browses an infected website with a browser that has a security hole a virus will get into the network. If it is a certain type of virus it could start replicating itself within the local network. A computer firewall defends against this sort of problem.
4. Update your operating system and browsers. Security holes are constantly found in all operating systems and all browsers. Software updates patch these holes.
5. Use a good and up-to-date antivirus and spyware program. These programs help prevent damage from viruses that do make it to your system.
6. Backup your data. Short of isolating a computer it is impossible to 100% secure a system. If you backup your data then should the worst occur having good backups will prevent disaster.

The above represents the basics and go a long way to protecting computer systems.

Why Does My Computer Take So Long to Boot Up

Are you in front of that computer monitor staring at the hour glass icon that has been up on your screen for five minutes? You have to check your e-mail before you go to work, but your computer is taking forever to boot.

When you install a new program, it likes to believe it is important so it puts itself in your start up folder. This makes it turn on when your computer starts up. When you get several of these, Windows is so over burdened with programs that it is super slow.

First and foremost, you must go into the Start Menu, select Run, type in “msconfig” (without the quotes), which will bring up the System Utility Configuration.

Once you have done this you can try deleting old programs that you don’t use anymore by going to your Control Panel and selecting Add/Remove Programs. I just did that to my computer and noticed that I had an old video game installed that was taking up 300 MBs and I haven’t used it in over 6 months!

Lastly, once you have done all of this run a Disk Defragmenter to put all of the files that naturally get spread out over time back together. To do this right click on My Computer, Properties, Tools, Defragment.

Restart and notice the amazing change in boot up speed.

If you are still experiencing problems and are still askingFind Article, “Why Does My Computer Take so Long To Boot Up?” then I would go a step further and run a virus scan on your computer to make sure that there are no malicious files present.

Printing Your Way To A Green Earth

Before reading Jennifer Proia’s article I never knew that the ink used in printing contributes to the pollutions that endanger human existence. According to her, commercial printing process creates enormous amounts of carcinogens, hazardous wastes and pollution. Before we proceed to the solutions let us first familiarize ourselves with these few important words.

Carcinogen is a solvent that compose the mixture of chemicals used in press-cleaning solution. Chemical carcinogens include methylene chloride, benzene and perchloroethylene. Evidences show that certain industries such as printing are associated with an increased risk of developing bladder cancer. Bladder cancer is believed to be caused by carcinogens.

When presses and equipments are cleaned it generates solvent and solvents containing liquids. These solvents may be toxic or flammable and almost all are classified as volatile organic compounds or VOCs. Once in the atmosphere, VOCs combine with other pollutants. These pollutants form ozone, called smog. Smog is an air pollutant that aggravates lung diseases. Solvents may also cause water pollution if not discharged properly.

So how can we reduce, if not eliminate, the use of these harmful solvents?

One way is by choosing printing inks. There are two types of ink, the petroleum-based ink and the soy-based ink, also known as soy ink. Soy inks are made from soybeans. It contains soybean oil used in cooking oil, so it is non-toxic. When used in printing, soy ink creates rich, vivid colors. It is safe because it decompose without harm to the environment. Soy inks are accessible. They promote paper recycling and create less waste on press.

So why use harmful ink if you can use earth-friendly ink without compromising output and production?

Another way to prevent pollution is the local exhaust ventilation or LEV. LEV removes offending materials before it can mix with air. With the proper application of LEVFree Reprint Articles, cleaning solvents can be quickly captured. Pollution can be also minimized by using water based cleaners and solutions with carcinogens at concentration below 0.1%.

It is very important to know the product you are using. Read policies and rules regarding chemical use. Be aware of the bad effects it may cause. Dispose of waste materials properly.

How To Stop The #1 Cause Of Computer Slow Downs And Crashes!

Imagine that you start up your pc just to find yourselfstaring at a blue screen with white writing, termed “theblue screen of death” by those at Microsoft.

So you push the power button to shut it down, and when youbringit back up it just crawls. Within a few minutes it goesback to theblue screen of death.

This happened to a friend of mine. When she asked me whatshe could do, I asked her if she had ever defragmented herpc.

She got that “deer in the headlight” look, so I knew shehadn’t. Defragmenting her pc, after 3 years of never doingso, took about 14 hours to complete.

One of the main reasons that computers slow down is poormaintenance practices.

Unfortunately, when you buy a new computer you don’t usuallyget much instruction on how to maintain it. Poor or nomaintenance allows your hard drive to become more and morefragmented which will slow it down over time.

To best explain hard drive fragmentation think of your harddrive as a file cabinet. In this cabinet there are folderswith documents (files) in them.

When you need to work on something you open the foldercontaining the necessary file, pull out what you need andput the folder back. The files go on your desk so you canwork on them.

Over time certain files don’t get put back, or they get putback in the wrong places.

When this happens on the hard drive it leads tofragmentation. Think of defragmenting as going through allof the files on your desk, and in the cabinet, and puttingthem all back in order in the correct folders.

Just as staying in this state of disorganization would leadto a significant loss in your own productivity, the samething happens to your computer.

Eventually this even causes crashes because of how scatteredall of the information gets.

Disk fragmentation can even shorten the lifespan of yourcomputer because your hard drive works so hard that it wearsout faster.

So the one step solution for this part of computermaintenance, run the defragmenting tool that comes withwindows at least once every couple of weeks.

Do this by clicking Start, click All Programs, clickAccessories, click System Tools, then click DiskDefragmenter. Choose the disk you want to defragment andclick the defragment button.

Alternatively you can get software that will automaticallykeep your disk defragmentedPsychology Articles, like Diskeeper by ExecutiveSoftware.

Take care of your pc maintenance and you will continue toenjoy the speed you experienced when you first made thatinvestment!
