Diagnose Types of Computer Viruses

There are different types of computer viruses, depending on the nature of the executable program and what the rogue programs actually do when they begin infecting a host system.

Differentiating viruses and spyware

Technically, spyware, malware and adware are not types of computer viruses. There is often confusion here; most users call all undesirable programs viruses. However, for the sake of technical clarity, we must correct this.

Computer viruses, like their biological counterparts, are known for their self-replicating capabilities. This means the virus can spread from one system (a system is your personal computer, laptop, etc.) to other systems.

Back in the nineties, MS-DOS viruses and BIOS-infecting viruses often spread from unchecked floppy disks that passed from one user to another (and consequentially, one computer to another).

Many of these viruses wiped out vital documents and other system files. Some of these MS-DOS viruses were considered as "joke viruses" because they tend to deactivate after one appearance. However, the same can not be said of computer viruses today.

Mode of infection

As we have mentioned before, there are varying types of computer viruses based on what these programs do. A non-resident virus is the simplest type; it's composed of a seeker module and an infectious module. The seeker module is responsible for finding individual files to infect. When such files are found in the infected host system, the infectious module is activated next to infect that file.

Resident viruses on the other hand, have not been created with seeker modules. Instead, these viruses have been designed to load whenever the system does. It waits, like a hunter, in the background until target file types are activated by the user.

Fast-infectors and slow-infectors

Resident viruses are further categorized based on specific actions of the programs within the host system. Fast-infecting resident viruses tend to infect each file that has been activated or used in the system (you can imagine what this kind of virus can do to a school computer system).

Fast-infecting resident viruses are lethal to low-grade antivirus programs. If the antivirus program does not use heuristic methods to trace potential viruses, the fast-infecting resident viruses can "ride" on the scanner program and infect each file that the virus program scans.

The polar opposite of fast-infecting resident viruses is slow-infecting resident viruses. These viruses tend to avoid detection by activating only with specific actions (like file transfers). Since the mode of infection of slow-infecting resident viruses is limited, many anti-virus suites find the offending virus before it can cause any real harm. …

SocialGo – Social Network Maker Review

SocialGo is the answer for many today who wish to create their own professional-grade social network designed for their particular interest, business, or group. A social network is of course, a group of people united by their common cause, business, or interest. Thus it is a computer platform allowing users to customize their network according to the amount of privacy desired, assorted features and permissions. Permissions outline who may view personal information, or information regarded as secret or semi-secret to a company for example.

Who uses it? Various groups, entrepreneurs, and businesses utilize it. Their goal is often to being a community around their brand for instance, or to build customer meaningful relationships, or even to create a communication channel for the members of the network.

What’s special about it? Basically the fact that thousands of members have found that they can construct direct revenue streams from the network they create.

What can be in it? You can utilize this network for any text you wish to publish, as well as any photos or videos you wish to include.

What’s the difference from just a website? With this social network, people can of course read what you wish to write, but in addition they can respond to it. This allows people to become a part of the network, in that they can actually share and contribute to it.

How can one monetize this network? There are a number of ways to make money with it. For example if you provide a service, you may charge for the service. SocialGo supports PayPal for example for billing purposes. Another means of monetizing it is to host advertisements and charge the advertisers. This works very well if you have a very active network of course.

What if I need help? There are a number of ways to get help, such as joining the Owner’s Network, speak to sales agents, get a support ticket, etc. There are also a huge number of tutorials that are easy to read and follow.

What does it cost? The top of the line costs $149.99 per month, and it gives you anything that a business would need to create the best most attractive network for your brand, existing product or website. Or you can get a network starter account for only $4.99 per month. Then instead if you wish, you can get a free account if you are for instance a group of concerned mothers wishing to chat about the school your kids go to.

What else is available? There are a number of other services available, for instance sending out billing and collecting, removing all traces of the network on your site (known as white labeling), or separate storage and bandwidth blocks if you have an overly active large network.…

Sharing the Internet With Your Teens

The Internet is a source of fascination for teens. Put yourself in their shoes for a moment. Remember when you were that age, and the world lay at your feet, or you thought it did. Really, it was just your neighborhood or your high school. Teens today really do have a world at their feet. It is a virtual world, granted, but that does not make it any less influential.

It is a supreme challenge for parents to get up to speed on the Internet. Teens do not have that problem, the Internet moves at the speed of teens-that is, much faster than the average parent.

This is a disparity that needs addressing because the Internet is not only like the world in your living room, but it contains all that is dark and threatening about that world, and that is a threat that you are going to want to remove from your living room.

And your teens are probably not going to come forward and ask for help, unless you create a climate where that feels appropriate.

One of the first steps towards this climate is a parent that actually knows something about how the Internet works. An unworkable power imbalance exists in the family where the parents are Internet virgins and the children are anything but.

This means that we parents are going to have to roll up our sleeves and get in there, at least deep enough so that we become conversant on the ways of cyberspace.

By making ourselves aware of what the Internet is all about we reinstate ourselves as useful guides for our teens. If we do not they will wonder this alternately wonderful and sinister landscape alone, without protection.

So, now, when we roll up our sleeves and head purposefully towards the computer station, it is important that we leave behind our inner policeman. We need to come as friends or our teens will respond by going underground and there they will meet unsavory characters that we would not approve of.

Resist the temptation to kit out each of your teens with their own little desktop. I know this view is unpopular but, like separate TVs in each bedroom, it fragments a family, dissipates the nucleus of the home and makes it extremely difficult to know what is going on without having to effect random bedroom raids.

Try to restrict yourself to a computer station in the common area of ​​the house. This means that the family is together in their virtual endeavors. While you're about it, one TV in the common area is also a positive step for family interactions.

I like to call it family surfing. This is what you have to do to create an environment where you and your teen will be able to discover, together, the good and the bad and the ugly that all live on the Internet.

Your teen is illegally to sit at your feet and ask for an informative lecture on the possible dangers …

Computer Monitors – Is Higher Resolution Better? Part 3

The Hidden Problem

Your monitor outputs the signal it receives to the best of its ability. Your computer outputs as many frames as it can. However, the cable that connects the two together is normally the cheapest piece of junk your monitor manufacturer could find. Even if you bought an aftermarket cable, unless you really did a lot of digging, aftermarket cables are also often really expensive and still pretty terrible.

Each frame is data, 30 frames at 1080p is a lot of data, 60 frames of 1080p is twice as much as 30 frames. Now in part 2 we learned that 4K is four times as many pixels well it is also four times as much data per frame. This can add up to huge amounts of data being sent down the cable connecting your monitor and gaming PC. Your cable is probably not up to the task of transferring 4K video much less supporting higher frame rates.

There are four major types of video cables used in gaming PC’s; VGA, DVI, HDMI, and DisplayPort.

VGA is a bare minimum cable incapable of supporting high frame rates and resolutions.

DVI is much more complex with multiple versions of the cable but only the latest versions of it are capable of supporting HD video and frame rates.

HDMI is the most popular type of video cable. It is most commonly found in just one type but there are different types of HDMI connectors but more problematic is that there are now three types of HDMI cables and there is no way to tell them apart. Standard HDMI can’t support HD video, High Speed HDMI can support HD video, and the new HDMI 2.1 or 48G cables can support resolutions up to 10K at 120hz.

DisplayPort is the newest type of cable and is growing rapidly in popularity especially in PC gaming. It has one type of cable and two types of connectors so it is much simpler than other HD capable options. It natively supports 4K video at 120hz.

Now at first glance it seems like you have three good options but hidden problem is that the manufacture of these cables is almost completely unregulated and meeting the minimum specs is the only requirement not the complete specification. So a High Speed HDMI cable may support 1080p but chances are it won’t support 4K because it’s not required to in order to be labelled High Speed. The same thing applies to DVI and DisplayPort cables. Don’t worry though! You don’t need to spend a fortune for cables either. In fact most expensive cables are still bad cables!

Just get your cables from Monoprice.com and you will get the highest quality cables with the highest data transmission rates I can even find for prices cheaper than most cheap cables you can find! I don’t work there I just hate bad cables.

What does this have to do with upgrading to a 4K monitor? You need to have the right cables for …

Computer Monitors – Is Higher Resolution Better? Part 1

The Pixel Problem

We live in a world where everyone wants more and bigger is better. But we also know that is not always true! No one wants a bigger pimple or more STD's! Sometimes having more is just pointless. Like more of the tools that come with furniture you need to assemble yourself. Pixels are the same way. The human eye can only perceive so many pixels. Imagine pixels as sand. When you are standing on the beach you can see the grains of sand but when you are standing on a cliff looking at the beach you may know its sand but you can not actually see the grains anymore. Pixels work the same way. Get close enough and you can see that a pixel is actually smaller red, green, and blue lights working together to make you see a different color when you are further away. Get far enough away from your monitor and all you will see is a light in the distance. So the real trick is sitting at the optimum viewing distance for your computer monitor. That is determined by the resolution and the size of the monitor. The higher the resolution the smaller the pixels, the larger the monitor the larger the pixels.

So knowing those two pieces of information you can find out the optimum viewing distance. This is because the human eye can only perceive details as small as 1 / 60th of a degree of arc but I'll spare you the math and provide a few examples.

Monitor Size ——– Aspect Ratio ——- Resolution —– Optimal Distance
22.5 "========= 16: 9 ========= 1080p ====== 2.9 '
22.5 "========= 16: 9 ========= 4K ======== 1.5 '
30 "========== 16: 9 ========= 1080p ====== 3.9 '
30 "========== 16: 9 ========= 4K ======== 2.0 '

So as you can see any further away than 1.5 feet from a 22.5 inch 4k monitor and you stop seeing 4k anyways. Occasionally you get to 1080p around 3 feet. In between 1.5 and 3 feet you do have better than 1080p, although this introduces a new issue. Operating systems are not built for resolutions higher than 1080p which causes the text on a lot of the interface to be visually smaller. While there is software to help this it does not fix all text and often causes other text to be much larger than necessary.

When you are sitting closer than optimal distance you see all the possible details with no loss in quality. In order for you to truly enjoy a 4k monitor you need a very large, very expensive monitor and all the hardware to support gaming at that resolution which is also very expensive. …

Learn C Language To Clear All Your Basics

If you wish to make a career in the IT field, then you must know all the basics. This is the basic requirement to insert your foot into the world of IT. The basics of IT software start from the HTML. HTML stands for Hyper Text Mark-up Language and it is the most basic and effective languages ​​that you have to understand in order to perform well in the IT field. The other basic requirement that you have to fulfill is, learn C language. C stands for Compiler, which means that this language will compile all the codes in order to create something substantive. The C language is perhaps the most basic versions of the languages ​​today. There are many advanced versions of C language available today, such as C ++ and C #. Where C is the oldest of the languages, C ++ has the advantage of being a step above the C.

The C ++ language is also known as the Object Oriented Language. Then comes the C #, which is the most advanced versions and can be easily related to Java. The best features of C languages ​​are that they can be used for developing web based applications. I would also like to mention that the computer programming is not everyone's cup of tea. People who work on computers work hard, but they hardly move from their desks. The computer programming task is brainstorming and eye torturing, so everyone can not do it. If you like working on computers now, then believe me, you will run away from it after a few years. But, if you still want to make a career in this field, then it is important for you to have an in-depth understanding about the C, C ++ and C # languages. You require a PC with decent configuration in order to learn these things.

I would recommend you to take a professional training to learn these languages, rather than trying it yourself. You may be able to learn a lot of things through video tutorials, but there is a specific pattern to learn all the things, which you may not be able to know if you learn through the internet. A training center will be able to guide you through each and every step related to these languages. If you want to learn a single language, then I would suggest that you should go for C # Programming. Many students and working class people look for the professional training centers who can teach every single detail about this language. It is so important to have a complete knowledge about C # in order to achieve success in the programming world.

There are many other platforms available today, but the converging point remains the same. No matter if you learn PHP, ASP.Net, Java or any other Programming language, you need to learn C, C ++ and C #. I would also like to mention that it is essential to find the right training center, …
