If you have ever had a computer problem, at some point the thought that it could have been caused by a virus has crossed your mind. Perhaps your virus checking program has started telling you about all kinds of things it thinks it has found. Even if neither of those has happened, you will ever be confused with a problem from a virus. Perhaps even a backdoor virus or backdoor Trojan.
Disguise is the name of the game for these viruses. They will appear to be one thing but are really something else. They open a backdoor into your computer allowing the REALLY malicious acts to take place. Something could be installed on your computer or it could be something on your computer that simply watches your actions until it something catches its interest. Then this Trojan jumps into action and transfers whatever information it found to the computer it has been told to talk to. Your personal information can be stolen very easily in this manner. You have no idea it's even happened.
Viruses and Trojans typically have names that do not tell you much about it. What is really helpful is for the virus protection program to tell you the file or files that house and hold the code that runs the viruses. A good virus protection program should provide that information on most viruses it detects.
The virus protection program can attempt to disinfect you computer. Formatting your hard drive is the only guarantee you will get rid of a virus. But a good virus protection program can help a great deal. It will do its work, and provide information. Then if problems are still occurring the burden falls on you to try to eradicate the problem. This is where even more information can help.
You often will be told to search for files on your hard drive. Sometimes you will be given a directory to look in. However, one trick virtual all Trojans and viruses use is to have file names that look files currently in your operating system. This makes it more difficult and confusing to find the correct file. It could be just the extension is different or perhaps a single letter has been added to the file name. Below is a list of files that are used by some of the most common Trojans and viruses.
esktop.exe – Belongs to the Backdoor.SdBot.md Trojan and the FFIsearch Spyware.
desktop.smm – Belongs to the Backdoor.SdBot.md Trojan and the FFIsearch Spyware.
ddhelper32.exe – Contains the backdoor software BDS / Sub7-220.Srv and Backdoor.SubSeven.
sys.plg – Belongs to the Backdoor.ICR Trojan.
gld.exe – Belongs to the Backdoor.Zagaban Trojan.
rlid.exe – Added by LIXY Backdoor virus.
winupdate.exe – Added by WORM_FALSU and is a backdoor Trojan.
wupdt.exe – Added by IMISERV virus and backdoor Trojan.
tskdbg.exe – Added by FLOOD.E VIRUS.It and is a backdoor Trojan.
winstat.exe – Belongs to Kodorjan Trojan.Kodorjan backdoor Trojan.
There is much more information available. Using a search engine, search for the file that you are concerned about. You will get a list of links that describe the file or process you are searching for. There are many, many other viruses and Trojans. Many use other files. So it is necessary to always search.
Using Windows Task Manager (Ctrl + Alt + Del), and selecting the process tab you could see a process that seems to be doing a tremendous amount of work. But for some reason nothing is really happening. All that effort spent by the process could be going on behind the scenes. It's being performed by a backdoor Trojan virus. To get more information on what may be happening, go to the website stated above and search for the process name. It will tell you whether that process is safe. If it is not safe, often a course of action to follow is recommended. It may also give you some idea as to why it is working so hard!
In 1986, the World was introduced to the laptop computer. It is probably the best innovation of recent times, though it is tough call. Since the 1980's, we have seen a whole bunch of nifty, cutting edge electronics and gadgets, including video games and cellular phones. Of course, the laptop of the 80's was big, bulky, heavy and really, really expensive. These days, laptops are more affordable than ever, more lightweight, more stylish and getting on-line is a common task, even at restaurants.
People can conduct business from anywhere now, and they do. The new challenge of transporting your laptop safely to your destination has been met with the design of backpack computer bags that will protect your laptop during it's journey. Leaving home with a laptop computer is as familiar as grabbing the car keys and so is using a backpack for laptop carrying. What makes this different from a traditional backpack is that for one, there is a cushioned area that will be used to help with storing the laptop computer. A laptop backpack works simply as a protective backpack that can be used to store a laptop computer in.
There are always storage areas on the inside and outside of the backpack computer bags to accommodate the laptop power cord and other accessories, like a wireless network adapter and storage disks. There are different types of backpacks for different laptops because there are many laptop computer sizes on the market. It helps to check with the height, length and width of the laptop that is being used and how much space a backpack can handle when looking into the right type of backpack computer bags.
There are people who need it office purposes while there are others who need it for gaming purposes. All of these requirements have different specifications and it also becomes cheaper if you construct your own computer. Also, if you have built your own computer, it becomes easier for you to change the components or make repairs when there is some problem.
There are basically 8 steps which will help you in building your own computer. The first step is to figure out the purpose for the computer. Make a list of all the things that you need and as per it, find out which components which will work best with it. Make sure that you decide whether you are using brand new components or old pieces. The next step is to find a place where you can work without the normal problems of dust and disturbance. Also, make sure that there is no carpet as the presence of the same can lead to static problems. The next step is to unscrew all the parts and figure out the requirements. After this is done, get the feet, power supply and the inner fan for use. The motherboard should be kept handy for installation. Although most of the components come with screws nowdays, there is always the chance of getting one which does not. In this case, you will have to mount all the other parts before pairing the motherboard. Always remember that the screws should not be overtly tight as it may pose problems in the fitting of the computer.
The next step is to configure the motherboard along with the CPU and the cooler. Now attach the power cord to the motherboard by connecting it to the power outlet. There are also smaller power cords which need to be attached to the LED screen and other components. The next step out here is to install the hard drives and other disks by using the manual instructions that are given along with the hardware. This should be done carefully so that there is no untoward mishap. Finally, figure out which operating system is the best for your needs and install it accordingly. Now that all this is done you can sit back and enjoy!
Both carbon and carbonless paper can be used to make copies of documents without any electronic devices. There are differences in each kind, both in how they are made and their uses. Overall, 3-part carbonless paper is a more popular option than carbon paper alternatives, and here is why.
Carbon paper is the original version of electronic-free document copying. It is coated on one side with a dark, ink-like substance that usually contains carbon. It makes copies with the creation on the first document.
A sheet is put in between the original and blank sheet the user wants the copy to appear on. They write or type onto the original and the pressure from the application puts ink onto the blank sheet. This creates a carbon copy.
Carbon paper was first used around the 19th century with a patent for something called a stylographic writer. A few years later, another inventor created a typewriting machine using carbon paper as part of its function. This means carbon paper was discovered and growing around the same time.
Carbonless paper, also known as NCR paper, is a better and more popular alternative to carbon paper. It is stain free and biodegradable and easier to transfer. It also relies on pressure from a writing utensil in order to create the chemical reaction that leaves a copy on pages below the top copy.
To make two copies of a document, papers would have a white top sheet and one colored second sheet below. This is called a two-part or duplicate. To make three copies, there is a white top sheet and two colored sheets directly below. This is called a three-part or triplicate. Four copies would be called a four-part or quadruplicate.
Sometimes, users requires stacks of ten or more copies. This is easy to do with NCR paper. Carbonless copy paper is supplied to the end user collated in pads or books. They are bound into sets using glue or staple. Loose sets or continuous stationary is widely used in printers. Businesses can also specially order as many stacks of carbonless copy paper as needed.
For a 3 part carbonless paper, there are three sheets. The first is the CB sheet that is the original to be copies. The bottom part of the sheet is coated in a layer of microcapsules that contain color formers.
The CFB sheet is second. The top side is coated with a receptive layer which reacts chemically with the color former on the top CB sheet. On the bottom of the sheet, a transfer layer with microcapsules transfers the copy to the last sheet.
The third sheet, or CF sheet, is on the bottom of the set. The top side is the receptive layer which reacts with the microcapsules color former on the sheet above it. The receptive layer is most often manufactured using activated clays.
Carbon and carbonless paper is mostly used to make copies of receipts. It serves as a backup operation in case computer systems fail. These paper options are also used to transfer invoices, service tickets, sales order, and purchase orders. Carbon and carbonless paper is used by modern artists as a surface for beginning a painting.
Carbon paper has some unique uses. Police offers use carbon paper for evidence vouchers. Prison inmates are required to use carbon paper when writing letters or other notes so the prison has a copy. Business forms utilize carbon paper for purchase orders and invoices. Banks and small firms are the biggest buyers of carbon paper.
Carbon paper is also commonly used among tattoo artists. The artists can practice draw designs and show it to the customer as they work on it, making changes as needed. The paper is moistened and pressed to the skin to leave a carbon outline. Customers can also bring in a design or message they want tattooed and carbon paper transfers it.
Carbonless paper can be used for these uses and more. Quotes, legal forms, employment applications, insurance forms, proposals, and delivery forms all use carbonless paper. NCR paper can also be used for requisition forms, tracking manifests, and contracts.
Poor posture — an epidemic in 2010?
We all seem to be spending a higher percentage of our days hunched over our computers. Whether we’re at work, at the local Starbucks, or at home, most of us spend hours a day at a computer. Email and social media have become an integral part of our daily lives, and most of us are slouching while we’re at our computers.
To make matters worse, most of us are still spending significant time watching TV and driving, two activities where most people are not in ideal posture.
Remember you’re mother telling you to stand up straight? Well, think about today’s kids who are at a computer or playing video games for most of their days. Poor posture is rapidly becoming part of our culture and the negative effects go far beyond a sore neck and bad back.
Bad posture = poor health
People with poor posture suffer untold numbers of negative consequences. These can include obvious issues such as neck and back pain, misaligned spine, rounded, slumped shoulders, osteoporosis and arthritis. But it can also lead to less obvious side effects including decreased energy, poor organ function, abdominal discomfort, and scores of other problem.
Additionally, poor posture gives one the appearance of poor health, low self-esteem, and an overall lack of confidence.
Posture corrective braces, the miracle cure?
Traditional posture braces come in various sizes, materials and configurations. From thin, elastic, over-the-shoulder posture bras, to Velcro vests and back braces made of surgical tubing, they all attempt to do the same thing: pull one’s shoulders back to maintain an upright stance and straight, correct posture. The problem with most posture braces is that they actually do put the user into correct posture. So why would that be a problem?
The problem with traditional posture braces is that they do the work for you. The passive nature of having one’s shoulders pulled back serves to weaken the back muscles, which actually worsens one’s posture over time, thus defeating the very purpose of using a posture correction brace.
Most people who have tried traditional posture braces have experienced the discomfort, the chafing under the arms, and the difficulty of use most devices offer, but most don’t realize that in the process of trying to improve one’s posture, the user could actually be causing long-term atrophy of the muscles in the back that are required for good posture.
