What Anti-Virus Software Consists Of

Anti-Virus software consists of programs on your computer that make an attempt to identify and keep computer viruses off your computer. The anti-virus software will most likely use a couple of different 

techniques to make sure the viruses stay off your computer. The software will start to scan all your files you have saved so that it can search for known viruses that will match definitions in a dictionary made only to detect a virus.Having anti-virus software will protect your computer from any virus an unknown person could give you. 

The software will identify suspicious behavior from any computer program that might show signs of infection.These analysis may also include data captures,port monitoring and other methods that you may or may not be familiar with.Almost all commercial anti-virus software use both of the following approaches,with an emphasis on the virus dictionary approach.

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. 

I have talked about the dictionary approach,now let me explain what this is.If there is a piece of code in your file matches any virus identified in the dictionary,then the anti-virus software can take one of the following options.It will first attempt to repair the file by removing the virus itself from the file.Next it can quarantine the file,such that the file remains inaccessible to other programs so that it's virus can no longer spread.

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.

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 fiance 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.

Hackers Do Exist-Get More Information About Anti Virus

In the early days of personal computers, in the age of the DOS command-line operating system, there were viruses that hid their presence from the users and anti-virus programs. They did it by intercepting some system calls that were responsible for reading the files, and lied to the system by filling these calls with fake information. You could view an infected file right in front of your eyes and see nothing but legit code! These viruses were called 'stealth' in those days.

When computers evolved, Windows replaced the DOS. Old viruses did not run under the new operating system, and it wasn't easy to develop simple hacks to intercept system calls in Windows. But time has passed, and now there's a new wave of viruses that can work on Windows and hide their presence even more efficiently than the stealth viruses of the old days. These new viruses are called rootkits.

Microsoft tried to address the problem by releasing their own Rootkit Revealer. 

The Partizan technology is unique to UnHackMe. Microsoft states that there exists no sure way to know of a rootkit's presence from within a running system. Instead of trying to combat rootkits on their own ground, Partizan fools them by booting with the operating system and taking control before any rootkits can load. Anti virus programs can be very beneficial to you and for your computer system. 

While being a correct concept, this tool fails on too many levels. Microsoft Rootkit Revealer is intended for use by system administrators and software developers. The results of its work are not detections but rather hint that there's something in the system that's hidden. And of course, Rootkit Revealer does not remove rootkits, making its benefits questionable at best for a regular computer user. Being the first to load, UnHackMe can safely watch all stages of the Windows boot process, effectively detecting and terminating any activities attempted by the rootkits.

Once there's no rootkit in the computer's memory, detecting and removing one is a matter of routine. UnHackMe can remove known rootkits by itself or simply block the rootkit from loading into memory and pass control to your regular anti-virus.

Scanning your entire PC for the presence of a rootkit with a regular antivirus can take hours of time depending on the number of files and programs you have. UnHackMe takes scanning speed to another level by taking only a few seconds every time your computer loads.

Complement your antivirus with a rootkit detection and removal system and liberate your PC from rootkits! UnHackMe with Partizan technology is highly compatible and designed to complement other antivirus solutions instead of conflicting with them. Antivirus and anti-rootkit products often conflict with each other. 

Not UnHackMe! You can safely pair UnHackMe with an antivirus of your choice, providing ultimate protection against all kinds of anti viruses and rootkits. Good luck and I hope that your computer experiences get better each time you get on. 

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.
