Antivirus Is Protective Software Computer Science Essay

Antivirus Is Protective Software Computer Science Essay Antivirus is protective software designed for protecting your computers system smart cell phones against Virus, Trojans Hijackers etc. These all Viruses, Trojans Win32 etc are called Malicious Software in computer world. All Antivirus software run in the background at all times to protect defense your computers system smart cell phones some antivirus are automatically updated through internet some antivirus are needs manual updated through internet to protect your systems against Malicious software. Introduction: Antivirus software provides an many essential layer for multitude of the Virus, win32, Trojans worm etc. The first document removal of the computer viruses was written by Bernd Fix. There are two types antivirus application in the computer world so that the time of the Atari ST platform designed in 1987 the first one was G Data second was UVK 2000 made by Bernd Fix in 1987.The word Antivirus is come from the word Antibiotic which means implies combat with an invading force of the programs. Fred Cohen designed the strategies relative to an Antivirus software program in 1988 to solve the virus problems. The old previews years Antivirus software are not so good because those software only detected the Virus Spyware etc remove it from your computers system damage your some operating system files inside your computers now AntiVirus software much better than old ones because it detected the virus remove it without deleting your operating system files inside your computers it als o fight against new malicious software which come from internet network. Well in the preview years Antivirus software are not completely free downloadable on the internet means you could only find some antivirus software with trial version now Antivirus software are completely free download without trial version . New Antivirus also checked the incoming outgoing mail, email attachments etc. It also have internet security for internet threats. Advantages and Disadvantages: Antivirus software is very useful in the preventing, controlling, virus many more viruses program, which can damage the computers components from inside operating system files to. Antivirus software are used for the methodologies for searching killing Viruses some of the well knows patterns of computer data programs. Antivirus programs are very effective against the viruses program, whose is the biggest threat for your computer systems. Antivirus program has some limitations drawbacks on the other hand, which effect on the computer system performance. In the computer world, inexperienced users can have many problems with the antivirus programs or software such as inabilities to understand, threats of the software success of the antivirus programs software are dependent on the ability of the user to understand Or knowing the right kind of balance between the positives negatives things in the computer world. Antivirus software or programs can cause problems during the installation window in the computer system or upgrade the Windows Service packs in the computer system. Antivirus software can be hampered some few software programs because it used it own firewall to block application to store in the computer system. e.g. True Crypt. Some Antivirus program will not knowing by the policy assessment before make it own policy when it install in the computer system. There are three major types of detection which is used to identify the potential threats in the computer system such as: Signature based, Heuristic based File emulation method. Signature based detection: In this method, you can identify the viruses malware virus software. Antivirus software can also compare the content files of the computer system to dictionary files of virus signatures because viruses are embed into themselves in the files shape or in pieces shape to infect the computers. Heuristic based detection: In this method, you can only detect malicious activity relative to viruses identify unknown viruses in the computer system. File emulation: In this method, it has using the heuristic type approach which it executing the program in a virtual environment which effect the action of the program performs it also carries out the disinfection actions relative to the programs which run in the computer. What is a Virus? Viruses are the category of malicious program code software, viruses are used for attempted to breach security value break them damage data of the computer system display unwelcome messages on the display screen when the antivirus program for gabbing user passwords on a networks are called LOGIN.EXE. These real LOGIN.EXE programs which have intruder or infect the user programs are called Trojan Horses when viruses program fall into the Trojans category than these viruses program have the ability to reproduce themselves again again until users computer systems slow down performance processing to any application it infected the your operating system . Why Do Viruses Exist? Now-a-days every computer virus programs are written by someone who wanted it to infect damage other peoples computer systems smart cell phones our world. So these Viruses program coding pass from computer to other computers system these viruses may be not have direct effect on the some computers but it affects on the other resources like(Disk space Memory) thats why these viruses are harmful it coding are very complex it also contain some serious bugs which damages the computer system pretty badly. How do I know if I have a virus want to protect my computer systems? If the someone computer systems are very running slower, freezing it displaying error messages again again than you should have the viruses in yours computers or operating system than u must install Antivirus software scan your computer system with latest internet updated of the Antivirus programs security to clear your computer with viruses. How did I get this horrible viruses on my computer system or operating system? Computer systems can be infected by viruses because: User using the Internet without having the latest updates of the Antivirus programs security installed into your operating system. User using the Internet without having a working firewall on the operating system or Antivirus software. User who opening the email attachments without knowing that whos will send him or her. User visiting unreliable website pages than viruses automatically stored into your computer because these website pages contains the infected viruses programs. How do I get rid of the virus? To get rid of the Viruses you should used latest Antivirus software or latest Antivirus program security updates now-a-days many new Antivirus software are able on the Internet free cost with one yeas updates free e.g. Norton Antivirus, McAfee Antivirus Kaspersky Antivirus etc. What are types of Virus in the computer world? There are several types of viruses in the world which your computers your operating systems for examples: Worms, Trojan horses, Logic bombs, Mutated viruses, Polymorphic viruses, Bounty hunters, Boot sector viruses Macro viruses etc. Worms: Worms Viruses are used to spread over a network of the internet hacks the computer system or operating system which connects with internet networks. Trojan horses: Trojans viruses are used to create a security hole in the computer programs or operating system infected the system files inside. Logic bombs: Logic bombs viruses are used to trigger the specific event means computer systems date programs of remote activation etc. Mutated viruses: Mutated viruses are used to rewritten by hacker users to change the behavior or signature of the programs made the multiple versions of the same viruses that infected the computer programs or operating system. So these viruses are also called variants. Polymorphic viruses: Viruses which are used to automatically change their appearance, like a chameleon by giving the virus a signature of the programs in encrypt-decrypt function so virus can only be recognize its own signature of the program. This kind of virus is called Polymorphic viruses. Bounty hunters: Bounty hunters viruses are used to modify signature program stored by Antivirus program in order to render them inoperable in the operating system. Boot sector viruses: A boot sector viruses are used to infecting the boot sector of a hard drive of the computer system.(just like MBR Master boot record) it also have infected the speed of the processer. Macro viruses: Viruses which came from email, email attachments etc to damage the operating system or hack the computer system . What is Firewall Spyware? Firewall: Firewall is software or program which have security tool to help limit internet network traffic with hackers or viruses to getting in your computer system. Firewall helped protects your computer from future hackers new incoming viruses. Spyware: Spyware are used to a multitude of malicious software programs which access your computer system. When Spyware viruses infect your computer system or operating system than it will slow down your operating system speed performance your computer system going to hang again again. Issues relative with the Antivirus software: Unexpected renewal costs: Some of the commercial antivirus software which includes end-user license agreements which effect on the subscription automatically renewed it, cost so much which you not expected. False positives: Antivirus software can used to identify non-malicious files which having the viruses so that it will be cause serious problems for the computer system because false positive make operating system files very unstable because of the viruses. System interoperability related issues: When the multiple antivirus programs running on the computer or operating system than it will degrade the performance of the operating system create conflicts in every programs running on the operating system. So this concept is called Multiscanning If the functionality of the few software programs can be hampered by the active antivirus software on the operating system. Effectiveness: The effectiveness of antivirus programs have been decreased in the previews year because of new good Antivirus software launch on the markets computer threat going dropped from 40-50% to 20-30% in this preview year. Rootkits: Rootkits are major challenge for antivirus programs on the operating system it had admin area access to the system to control, invisible hidden the EXE from the running processes of the task manager on the computer system. What is Cloud antivirus method? Cloud antivirus method is a technology that used the lightweight agent software to protect the computer system or operating system it also used for analysis the data with providers infrastructure. To implement this Cloud antivirus method we used the multiple antivirus engines which scanning suspicious files from the operating system this concept is called Cloud AV. Cloud AV was designed to send programs on the internet network where detection programs are used to improve the detection rates with multiple antivirus behavioral on the internet network. Online Scanning: Some of the Antivirus provides maintain of websites with free online scanning on the internet with the entire computer such as like local disks, critical area files relative to the computer systems. Well as you know that internet becomes the vehicle for communication in this world people using digital communication on the internet with very fast speed scope so that new kinds of viruses are increasing spread all over the world of the internet network. If someone will not want to install antivirus on his or her computer than he or she can easily scan his or her computer online this is quickly possible solution. What do u means by the birth rate death rate of the viruses? The Birth rate of the viruses: The birth rate of the viruses depends upon the one infected computer system or operating system which can spread this infection to other computer system or operating system. The Death rate of the viruses: The death rates of the viruses depend upon the infection found on the computer system or operating system destroy that computer system.

Stem Cell Research Persuasive Speech

I. Introduction: A. Thesis: I'm here today to convince you that we should continue to use stem cell research treat human disease and abnormalities. B. Claims: 1. Claim 1: To begin, stem cells have the ability cure thousands of people. 2. Claim 2: I'll show you that the potential of stem cells are endless and committing to research can only prove so much more. 3. Claim 3: Finally, I'll also explain to you how the plasticity of stem cells can treat such a wide range of disease. II. Body: A. Claim 1:†¦ To begin, stem cells have the ability cure thousands of people. . Evidence 1: To begin, in a 2007 issue of the National Right to Life News, therapy has saved the lives of victims of myeloma and congestive heart failure. The treatment would have stem cells travel through their bloodstream into their bone marrow to establish a disease free immune system. 2. Evidence 2: In addition, stem cell therapy has revealed beneficial effects on the regeneration of impaired heart muscles according to Alex Martin's 2012 article Stem Cell- Therapy-Saving Lives one Heart at a Time.This therapy has the ability to reduce the chance of heart failure and can restore all the parts necessary to a damaged heart. B. Claim 2: Next, is that the potential of stem cells are endless and committing to research can only prove so much more. 1. Evidence 1: In fact,the website for the National Institutes of Health resource for research states that stem cells may replicate many times unlike muscle, blood, or nerve cells. This means they are capable for long-term self-renewal, meaning these cells can divide and renew themselves for very long periods of time. 2.Evidence 2: Also, in 2009, the Internet Journal of Bioengineering explained how stem cells can go from unspecialized to specialized cells that have the ability to differentiate into a wide variety of cells. These cells are proving to be the mainstay of rengerative medicine. C. Claim 3: My final point is explain to you how the plasticity of s tem cells can treat such a wide range of disease. 1. Evidence 1: First, in a 2012 issue of the Las Vegas Review Journal, scientists have started banks for umbilical cord blood stem cells which are a rich source of stem cells, being able to repair or even replace damaged cells in the human body. . Evidence 2: Additionally, Mark Anstead has written in a 2011 issue of Mail on Sunday about the ability of stem cells to treat a genetic blood condition known as sickle cell disease. Through blood transfusion, stem cells were transplanted into the patient's bone marrow and within days, his bloodstream was populated with healthy new red cells and no longer has to take his medication. . III. Conclusion: A. Thesis: Today, I've tried to convince you that we should continue to use stem cell research treat human disease and abnormalities.B. Claims: 1. Claim 1: First, I showed you that stem cells have the ability cure thousands of people. 2. Claim 2: Next, I told you how the potential of stem cells are endless and committing to research can only prove so much more. 3. Claim 3: Finally, I showed you how the plasticity of stem cells can treat such a wide range of disease.

The Female Characters Of Ophelia And Gertrude Within The Text

This analysis of Hamlet will focus on the female characters of Ophelia and Gertrude within the text. Ophelia is the daughter of Polonius, she is a kind, sweet natured girl of who Hamlet has fallen in love with. However, due to the control of both her father and brother Laertes, has been convinced that she should spy on young Hamlet as to what his intentions are.

Throughout the text we can see that both Ophelia and Gertrude are oppressed by the male figures around them such as Claudius, Hamlet, Polonius and Laertes who are pivotal characters in the text. She also becomes more mentally unstable as the play progresses. Psychologically , gender can also be a difficult subject to analyse as nowadays your gender is not solely based on whether you are male or female, the terms of gender and sex are used interchangeably and acco rding to western cultures they are not purely connected to physical anatomy. However, focusing on the female figures of Ophelia and Gertrude in relation to the line â€Å"Frailty, thy name is woman† initially suggests that any one woman is the same as all women in society suggesting that they will always be seen as the weaker gender.
