Computer Problems that Drive you Crazy
Steve, looking disheveled, calmly rises from his chair at the computer desk, while pausing a moment to push the chair in before he leaves the room. Shortly after, he returns with the biggest sledge hammer he could find, and uncontrollably starts smashing the hell out of his computer. He starts to break a sweat before he stops as his arms can no longer lift the sledge hammer. However, by now, all that’s left is particles the size of wood chips. This scenario actually occurring is unlikely, but most people have had similar thoughts and urges. Such urges occur more often as the average computer user is faced with newer technology. As technology advances, so do computers users’ technical issues. Computer users are confronted with computer problems daily, from different types of infections to hardware crisis to software dilemmas.
Firstly, computers nowadays acquire many different types of infections. These infections range from viruses, to spyware and adware, to Trojan horses. The number of viruses in known existence exceeded 50,000 in 2001 and this number has grown daily since (“Number” 1). The good news here is the greater portion of viruses are not in circulation, but exist in archives and reference libraries for analysis (“Number” 1). Also, as for the most common viruses and those in virus libraries, anti-virus programs have a way to remove them. One difficulty users often face, is trying to figure out if a virus resides on their computer. Some viruses exist on a user’s computer without him / her knowing it for months before detection. Other viruses are immediately detectable and easily removed. Then the really nasty viruses make it apparent they’re on your
PC, but are seemingly impossible to remove so one simply decides to erase the hard drive and reinstall everything.
Next, the problem of spyware and adware has exceeded that of viruses. The makers of this nuisance have targeted the widest audience possible so the users of Microsoft Internet Explorer have the most risk of being infected. Part of this problem is that the average PC user is unaware of other browser possibilities, such as Mozilla Firefox. This browser has gained tremendous popularity, and has been steadily converting IE users as they discover its security features and ease of use. According to Browser Statistics, the total percentage of IE users is down to 65% as of May, and Firefox usage is up to 24.
At the Aim Higher College there have been recently discovered malware on the campus systems that are due to many recent attacks. I used an Anti-virus protection software called AVG on the computer systems on campus and ran a whole computer scan. The results came back very quick of numbers of malware being high and medium priorities that these should not be taken lightly. Furthermore, the scan found many viruses, Trojans, and malicious software and applications.
I decided to read the book by David Harley called Viruses Revealed. This book goes into great detail about the different kinds of viruses and virus mechanisms, the solutions to these viruses, studies on different cases of viruses and then the social aspects of viruses. In the first part of the book, Harley talks about the problems with viruses. A virus is a program that infects other programs to modify them. “Infecting means that a virus will insert itself into the chain of command” (Harley). The virus structure was defined into three different parts: Infection, Payload, and Trigger. The infection is defined as the way or ways in which the virus spreads. The payload is defined as what the virus does besides duplicating itself. Trigger is defined as the procedure that decides whether or not the payload is necessary. Harley also talks about the difference between damage versus infection. The major difference between the two is that many users have infected documents or applications on their computer. Whether or not those applications are run is the difference between the two. In part one Harley also converses about Trojan Horses. Trojan horses are normally known as a virus, but he shoots that down. Harley says that Trojan Horses are normally not viruses, but just a worm that goes from computer to computer. After talking about different kinds of viruses and worms, he goes into Anti-Virus softwares. There are two different kinds of anti-viruses. One being virus-specific. Virus-specific means that every time a virus is found on your computer, it is identified but not detected. Generic scanners do the opposite. Generic scanners detect viruses but do not identify them.
A computer virus is designed to self-replicate, self-install, and attack the root functions and system of different programs without authorization or the user’s knowledge. Virusesmainly affect the root of a computer system.Virus can destroy and damage most important part of our hard drive, the boot sector, where information about all files has been stored. Viruses may alter directory paths and may change
Imagine this; you are sitting at your desk looking at a bunch of pictures. Just a normal scene, what could go wrong? Suddenly, you’re attacked by deadly things that are trying to steal your personal information like your credit card numbers, email address, all your passwords, everything. Could this be the work of ninjas? No (bet that is what you first thought though). What about the FBI? No. Then what was it? It was a virus. If you hadn’t figured it out by now, you were looking at pictures online using Google images (for all you Bing fans, I’m sorry but Google is much better). You were downloading pictures from Google and one of them happened to contain a virus and it was downloaded with one of the pictures. How do I know this is a virus? The answer is that I don’t. I didn’t give enough symptoms to diagnose this. To the pros at hacking and security, you may know that viruses are not the only threat. If you are new to the world of computers, you might not. The three types of malware that will try to harm your PC or your data in any way are Trojans, worms, and the most famous, viruses. These three are very different and all are terrible for you and your PC.
What is virus? A computer virus, according to Webster's Collegiate Dictionary, is "a computer program usually hidden within another seemingly innocuous program that produces copies of itself and inserts them into other programs or files, and that usually performs a malicious action (such as destroying data)". Two categories of viruses, macro viruses and worms, are especially common today. Computer viruses are never naturally occurring; they are always man-made. Once created and released, however, their spread is not directly under human control. One example of a virus is the Anna Kournikova virus, which comes in the form of a picture sent through email.
In the world today, computers are used in every field. Be it a major space exploration or a small chore like cleaning our room. The use of computers has made our lives easier but at the same time a computer failure can make our lives miserable too. We trust computers more than we trust anything else these days. We use computers to communicate, share personal information, buy goods online, etc. We also trust computers with our safety. Starting from house alarm systems and other safety devices we have now moved on to using computers to Test Car Crashes.
The internet has developed into the go to source for communication, finding information, and entertainment. People look for the best way to use it and to get the most out of it. Browsers are programs that bring the World Wide Web to people on a variety of different devices. These platforms for exploring the internet have become more and more advanced as we make progress in the world of technology. They have to keep up to make sure they meet society’s demands and preferences. Two of the biggest browsers today are Google Chrome and Mozilla Firefox. They both bring the best that browsers have to offer.
Computer Viruses are a form of malware that are small software programs that can spread to different computers. They cause interference to your computer’s operations,
“A digital world we became”. These days individuals turned to use computer systems in everything in their lives. They even use them in manufacturer instead of employees. I did not say that technological innovation is not essential for us but sometimes the technological innovation disregards our role in life. Technological innovation is very essential to any lifestyle to flourish. Technology contains cell mobile phones, laptops, machines, Ipads and many other factors. Not also they include all the excellent stuff but any great factor comes out with a drawback. Technological innovation has some drawbacks, and the most essential one of them that we will mainly talk about is the malware.
Computers are main technological features that allow criminals to step into unsuspecting victims lives. With a simple piggy-backing program hackers are able to track every keystroke made by the victim. One such program is called spyware, not to be confused with adware, which is often referred to interchangeably with spyware, but is potentially harmless (Louis 15). Spyware, hidden within downloaded software, implants itself deep within a computer’s hard drive, allowing it to track every move made by the user (Louis 16).
Internet Explorer, Chrome, Netscape, and Safari, these are a few examples of some of the web browsers that are used throughout the world. These web browsers have become even more common as the years have gone by. People use them in their everyday life to accomplish tasks that they need to get done. The beginning of this profitable and popular invention all started back in 1990.
Virus is one of the most common malware. Unlike spyware, virus is largely designed to harm useful programs or wreck down an entire operating system. There are many ways through which virus may enter a computer. The most common way is via email attachments. A...
Software viruses are parasitic programs that can replicate themselves, infect computers, and destroy data. Users can protect their data and software by using an anti-virus program. Hardware is sometimes stolen for the value of the data stored on it rather that for the value of the machine itself.
aspect of our lives, we are faced with computers. They are in our classrooms, cars, and even used
In today’s world the personal computer is as common as a toaster. Almost every household has at least one computer. According to a 2001 survey over 65% of the population in the United States uses a computer. We use the computer to surf the Internet, keep track of our finances, email friends and relatives and play games. There are limitless possibilities for the use of computers. They have made typewriters and filing cabinets and thing of the past. However like any other parts of our society the pc is not safe from being harmed. There are computer viruses and spyware applications that can attack your computer. If your computer has been freezing up, giving you strange illegal operation error messages, or just not working properly it may be time to rebuild it.
