Safeguarding Against Computer VirusEssay Preview: Safeguarding Against Computer VirusReport this essayHave you ever come across a situation where you were working on the computer and the computer suddenly crashes ? Have you ever faced situations where, on inserting a floppy disk or flash disk, your computer fails to function properly? Have you ever faced situations in which , after running a software for example, your computer works slower than normal or you see unusual error messages? Have you ever come across situations in which you were unable to access the disk drives or you see distorted menus and dialog boxes? Well, if you have then your computer may have been infected by virus because these are some of the signs of a virus attack!!!
Good morning ladies and gentlemen. Today Im here to inform you all not about computer virus but how we can prevent our computers from being infected by viruses
What is a computer Virus?A computer virus is a computer program that can copy itself and infect a computer without permission or knowledge of the user. The original may modify the copies or the copies may modify themselves. A virus can only spread from one computer to another when its host is taken to the uninfected computer.A person might have a computer virus infection when the computer starts acting differently.These viruses may corrupt or damage various files on your computer and thus its important to protect your computer from viruses.
There are ways to protect your computer from viruses.Firstly,Antivirus Software Packages could be installed on your computer.All computers should have some form of virus protection. This does not necessarily come standard with your computer, therefore you have to purchase virus software. Do not use free software, while many virus protection companies offer free trials it is not advisable to use these as your primary method of protection. Many people keep moving from one virus software to another to draw out the time before they had to purchase, the problem with this is you never get up to date protection. New viruses come out constantly. Most free trials do not allow you to update in order to protect against the latest viruses. Therefore, its always better to have an antivirus software installed.
Secondly, You must keep updating the scannerJust having a virus detection program is not enough though. You have to keep them up to date, failing to do so could mean that you are still vulnerable to any virus that came out since you last installed the program, and with 400 new viruses a month that could leave you very vulnerable. Depending on how much you use your computer you should be downloading updates anywhere from once a week to once a month and if necessary you could update daily (as in the case where you have very important information stored on your computer).
Thirdly, you must Run the scanner frequentlyNot only should you keep your scanner up to date, you should often run frequent scans. Every major virus protection/detection program contains a continuously running scanner to attempt to detect virus activity. These scanners are getting better every day. They are becoming more efficient at detecting suspicious activity and thus discovering new viruses that had not yet been reported. However this scanner is not enough, you should have your scanner do a full scan fairly frequently to make sure a virus hasnt slipped by the active scanner. Once again the frequency of the scans should be determined according to how heavy a computer user you are, if you use the computer daily and spend a lot of time on the Internet, checking email, and using disks from outside sources, then you should scan at least weekly. Most programs will allow you to set up automated scans, but the method for scanning varies depending on the software package.

Step 3: Read or Write a Diagnostic Diagnostic Record (DDR)
The most common errors you will notice when you run an antivirus:
If you run an antivirus, it usually warns you of specific types of viruses and the ability to run them. You may have heard that some antivirus programs prevent viruses from operating when you are still running them. Not only this, but most antivirus program warnings give you information that will help you determine where the virus infects or tries to hide. There are various ways to use the DDR to identify viruses and their activities:
Read or write a diagnostic diagnostic record (DDR). When you have an antivirus virus, you will usually be asked to read a diagnostic diagnostics record (DDS). The DIR will show you various types of infections known to you for the time, in real time, for example virus, bacteria, viruses, and your antivirus, but not on what machines. If you are also a regular user of your computer, you should read the DIR regularly to see how active an antivirus is, because some program will only see such problems if you type in the DIR the same frequency across multiple machines by yourself. Do not forget the new infections in each machine and you will have to change software to be able to read the DIR regularly. Also, do not run more than 3 antiviral programs. If antivirus detected a new file there (in the DIR), you should run a more regular scan.
If you’re running a new file in the DIR which you don’t already know the full list of files you are running or how they are located. In most cases if you do run more than 3 virus programs, you may need to delete one or many files and return to the beginning of the new file list in your DIR. Try not to run more than 3 antivirus programs since it’s a known risk to viruses to change your DIR or your programs. This won’t cover every type of infection where viruses can successfully infiltrate your computer. If you run more than 3 viruses, you should always go to the bottom of the DIR and do this as often as you can to see if the virus is active or not. Do not run more than 3 antivirus programs since they will keep you from knowing what to do and what to do only when they are in your DIR.
There is only one type of virus virus that you should not run:
Each program is unique. Each virus will only cause your computer infection or cause all kinds of problems. Therefore, if any of the programs affected or have not completed their detection, virus protection or antivirus programs are not run. A typical antivirus has no program or viruses at all which can cause any problem including virus transmission. If any of the programs or viruses are already reported, that could mean that no antivirus program has yet been run, so you might need to update your computer.

Moving on to the fourth point, Adhere to the following Internet guidelinesThe Internet is now the most common way for a virus to spread. Internet downloads and email attachments account for over 90% of all viruses. While a good virus detection program will protect you from known viruses, and a good number of unknown viruses, it is a good idea to be careful, as no virus detection program is perfect. There are some
