How Anti-Virus Keeps Your Computer From Crashing
I'll be the first to admit I did not know much about computers.I always thought when you got a computer it came with everything you needed.What I didn't know was that you always need an anti-virus on your computer to keep it from crashing.My computer of course came with that,but I did not know after a certain length of time you have to pay to renew it.
I always thought the terminally on a computer was strange.Things like anti-virus,checking the cookies,The mouse,seemed crazy to me.Well after I found out that I had been running my computer with no anti-virus program I didn't know what to do.My husband and I are on a fixed income so I couldn't really afford to buy anything else for the computer.It took me years to save up to get this computer.I never expected you could get something at no cost to you.I found out that there are many free sites to get a anti-virus program.
A lot of these sites let you download the anti- virus protection for free.That was right up my alley,free! Well after I downloaded it I had to figure out next how to use it.I am not really swift on a computer.I learned that I just hit the button that says start scanning and the anti-virus program scans everything and tells me if my computer has any viruses on it.I also learned you should not put a lot of things on your computer you really don't have to have on it.I love music so I would download a lot of my favorite songs on my computer.
That way when I get on my computer I can play my favorite songs.I did not know that slowed your computer down.I also loved to play games on the computer such as bingo or slots.I sure found out pretty quickly that not only can you lose your money fast,downloading those sites could have caused problems on my computer.I was told that the anti-virus program protects my computer from sites like those.After I was told I really didn't need those kind of things on my computer I went to my add and delete program and delete them.
My computer actually started to run faster after I did that.I also go to run and type in cookies and clear everything out of it.It would be to easy for someone out there who knows how to hack into peoples computers to get my personal information.Identity theft is also a big concern these days.I really trust my anti-virus program to protect me from such things as identity theft but I have to do my part also.
I need to be careful about putting my social security number over the computer,or most important my credit card number or my banking information.So remember to be smart about those kind of things and try to use your anti-virus program at least twice a week.
The Importance Of Having A Anti-virus On Your Computer
All of us who have computers probably have an anti-virus of some kind on it. One thing you may not know is that a lot of times those anti-virus protection for your computer comes only for a limited amount of time.I always thought I had a anti-virus protection on my computer. I would keep getting a pop up saying your subscription needs to be renewed. I always ignored it because I didn't know what it was for.It turned out that was my Mcfee Anti-Virus protection and I no longer had it on my computer because I didn't renew it.
I was running my fairly new computer with no Anti-virus on it. I did not know it was so important to have it until my step-daughter told me her computer had crashed. I asked why that happened,because she lost a lot of her work that was stored in her computer. She told me it was full of viruses because she didn't have the proper anti-virus protection on it. I think it is kind of funny that a computer can get a virus,but it is not funny at all.
There are so many people that hack into other peoples computers and cause all kinds of viruses on your computer.After I was told about this I really wasn't sure how to get a anti-virus protection on my computer. I thought they would cost a lot of money,but it turns out there is many free sites that you can download for free. These free anti-virus protection works just as well as the ones you have to pay money for.
One thing I also learned is to clear out the cookies on your computer. It will cause your computer to slow down if you have a lot of things stored in it.Without the anti-virus protection you must realize with all the information you have stored can be hacked into. To get to your cookies on your computer just go to start on your desktop and then go to run. A box will come up and just type in cookies and browse and that will pull up every site you have gone to while you have had your computer.
You can delete all that stuff except where is says index.It won't let you delete that out. So it doesn't take so long to delete you can highlight everything and hit delete on you keyboard and everything you highlighted will be deleted automatically.
You may think all of this really doesn't matter but it is very important to have an anti-virus protection plan on your computer and to keep your cache cleaned out so you don't get viruses that will make your computer crash. You also have a lot less worry about with all the talk about identification fraud because of different types of anti virus programs that are now available. Identification fraud can absolutely ruin and your family's life.

What Anti-Virus Software Consist Of
Anti-Virus software consists of computer programs that attempt to identify, thwart, and eliminate computer viruses and other malicious software (Malware). Anti-Virus software typically will use two different techniques to accomplish the following things, Examining,also known as scanning your files on the computer to look for familiar viruses that will match definitions in a virus dictionary.
The Anti-Virus software will also identify suspicious behavior from any computer program which might indicate if it has infection.Some of these analysis may also include data captures,port monitoring and other methods as well.Most of the commercial Anti-Virus software uses both of the following approaches, with an emphasis on the virus dictionary approach.
In the virus dictionary approach,when the anti-virus software looks at a file, it refers to a dictionary of known viruses that the authors of the anti-virus software have identified.If a piece of code in the file matches any virus that is identified in the dictionary,then the anti-virus software can take one of the following options.
1. Attempt to repair the file by removing the virus itself from the file.
2. Quarantine the file(such that the file remains inaccessible to other programs and it's virus can no longer spread).
3. Delete the infected file. To achieve consistent success in the medium and long term,the virus dictionary
approach requires periodic downloads of updated virus dictionary entries.
As civically minded and technically inclined users identify new viruses "in the wild",they can send the infected files to the authors of anti-virus software,who then include information about the viruses that are new in their dictionary.Dictionary-based Anti virus software typically examines files when the computers operating system creates,opens,closes or e-mails them.
In this way it can detect a familiar virus very quickly upon receipt.Note to that a systems administrator can typically schedule the anti virus software to examine (scan) all files that are on the computer's hard disk on a regular basis.
Although using the approach of the dictionary can effectively contain virus outbreaks in the right circumstances, anti virus authors have tried to stay a step ahead of such software by writing " oligomorphic," "polymorphic" and more recently "metamorphic" viruses, which encrypt parts of themselves or otherwise modify themselves as a method of disguise,so as to not match the virus's signature in the dictionary.
Anti virus programs come in many different types and it is important that you understand all of those types before choosing to purchase any for your home or office computer system. Research this some more before choosing which type would be most beneficial to you. Keeping your computer functioning properly is really very important because they sure do cost us all plenty of money!
Purchase an anti virus program for your computer now if you do not currently have one for your personal computer, otherwise you are going to be out a great deal of money once your computer becomes invaded by bugs!

The approaches are first the dictionary approach second suspicious behavior third other approaches.In case your wondering if we are talking about your computer or your children,we are definitely describing your computer although you may get a little laugh while reading this and thinking this computer is as bad as my children can be sometimes. At least for our computer we can get an anti-virus which will help solve a lot of the problems that can occur when you have a computer.

Anti virus software can be very expensive so please make sure that you shop around to make sure that you get the best deal that there is available to you. It is important to keep your computer functioning properly over time and by using this type of software you can easily do so, without so many threats occurring each time that you are on the internet trying to enjoy your time.
Third it will delete the file that is infected.So you can achieve the success consistently for the medium to long term,the virus dictionary approach does require periodic generally online downloads of updated virus dictionary entries.You should also know that a system administrator can typically schedule the anti-virus software to examine or scan all the files on your computers hard disk drive,and it can do this all on a regular basis.
Although the dictionary approach can effectively contain virus outbreaks in the circumstances,virus authors have always tried to stay a step ahead of such software by writing oligomorphic,polymorphic and most recently the metamorphic.Use your anti-virus at least two or 3 times a week so your computer can be protected now and future use.
The Benefit Of Using Anti-Virus And Spyware
We all need an anti-virus protection on our computers to keep from getting any bugs in the computer.You can now learn how to get anti-virus,anti-spyware,and firewall technologies that are on the market in a new ground-breaking product.You can now get all the protection you need against viruses,spyware and add protection against data theft and someone trying to hack into your computer.
You can do this by getting a multi-layer,intelligent firewall.I have learned quite a bit about the webroot anti virus and spyware and firewall. Some of the things I have learned is this is the best in it's class,it's easy to install,It gives you daily updates against the latest infections,free customer support and online support,custom removals of spyware,money back guarantee,safeguards your privacy and information,and real-time anti virus protection.

Another concerned question is Are computer viruses a bigger threat than spyware programs? You may also wonder why you would need both anti virus and spyware protection? Yes, viruses are still a threat,but over the past few years spyware,adware and other programs designed to gather your personal information have become a much larger threat than viruses.
Recent Industry reports indicate that in 2006,the number of new viruses detected dropped by 32% over 2005.However,the number of new spyware threats increased by 254% during the same period.So keep your computer safe and make sure you always have an anti virus protection on it.

Concerning Issues With Anti-virus
The ongoing writing and spreading of viruses and of panic about them gives the vendors of commercial anti virus software a financial interest in the ongoing existence of viruses.Some theorize that antivirus companies have financial ties to virus writers, to generate their own market,though there is really know evidence that we know of.Some of the antivirus software can considerable reduce performance.
Users may disable the antivirus protection to overcome the performance loss,thus increasing the risk of infection.For maximum protection the antivirus software needs to be enabled at all times-often at the cost of slower performance.It is also important to know that a person should not have more than one antivirus software installed on a single computer at any given time.This can seriously cripple your computer and cause further damage.
It is also sometimes necessary to temporarily disable virus protection when you install major updates such as Windows Service Packs or updating graphics card drivers.Having antivirus protection running at the same time as installing a major update may prevent the update installing properly or even installing it at all.When you do decide to purchase antivirus software,the agreement may include a clause that your subscription will be automatically renewed,and your credit card automatically billed at the time of you are suppose to renew without you authorizing it.
For example,Mcafee requires you to subscribe at least 60 days before before the expiration of your present subscription,If that is the case, the subscriber may contest the charges with the credit card issuer,but this course of action is likely to be at no avail to you if in fact the subscriber had authorized such a "continuous payment authority".
Some antivirus programs are actually spyware masquerading as antivirus software.It is to your advantage to check twice that the antivirus software which you are downloading is actually a real antivirus program.Some commercial antivirus software programs contain adware,
For example, the home/small business version of a CA Anti-Virus 2008 displays an advert for CA products whenever the desktop is unlocked after a period of when the computer is not active.It would be no surprise when viruses that plague the desktop and the laptop world quickly migrate to mobile devices.More and more vendors in this space are offering solutions to combat secure mobile handsets with antivirus solutions.
Anti virus programs come in many different varieties and range from cheap to really expensive but trust me, without an anti virus program you are going to end up being out much more money in the end because of the expenses of repairing or replacing your computer. You can find many of these types of programs for your home computer or office computer right here on the internet or in any computer store in your area.
Good luck with keeping your computer up and running properly and if you do not already have an anti virus program for your computer system, please consider choosing to purchase yourself one very soon, for a much more reliable computer, which we all need.
