Antivirus Freeware

Many people worry about protecting their computer. There are so many threats out there that you just can’t be too careful when it comes to the security of your computer and files. No one wants to go through the horror of having their computer stop working. There is the trouble of having to either get it fixed or replace it. You also then have to worry about the data you had on the computer. If you didn’t back it up then it is likely that you will not be able to retrieve any of it. If your computer was infected with a virus or other type of malware, then it’s possible your information was corrupted and even if you could retrieve it, it would be unusable. There are just so many threats out there that everyone needs to have some kind of antivirus protection. However, some people can’t or don’t want to pay for that protection. Admittedly, it is a fairly expensive ongoing cost of owning and using a computer. That is why it is great to have the alternative of antivirus freeware.

Freeware is open license software that anyone can use and distribute. Protection  software is some of the most popular and most frequently downloaded of all the freeware available on the internet. The main benefit of this type of software is that it’s free and usually good quality. However, there are some downsides to it as well. The main way that antivirus software protects a computer is by keeping an updated list of known virus files and code and checking every file that tries to gain access to the computer. The disadvantage of free antivirus programs in this scenario is that they may not have as updated a list as some of the premium antivirus programs. Another way antivirus software detects problems that might not be on that updated list is by an autonomous process within the software program. What happens is that when the program does not recognize code from its list of known viruses, it begins to search for code within the incoming file that resembles any problem code. It then runs further tests to see if this incoming file could contain any problems. The disadvantage here for free software is its ability to recognize malicious code that is not on its list may be vastly inferior to the ability of similar premium software. As with most freeware, there are trade-offs that come with free software that you have to be willing to accept.

Antivirus freeware may be an acceptable first line of defense for your computer needs. If you don’t do much downloading and are pretty light user of the Internet then your security needs will not be too extensive.

Virus Protection Software

The worst scenario any computer user can imagine is trying to access your files and the computer is unresponsive. Everyone fears the day when their computer will be infected with some kind of virus and all their files will be corrupted. At that point there isn’t a whole lot you can do. The best way to protect yourself against these threats is by prevention. There are so many different types of threats out there on the Internet that it is almost impossible to try and identify and eliminate individual threats yourself. You need to have the assistance of virus protection software.

Protection software comes in all different types and with many different features. However the goal of each one is the same: to protect your computer against malicious software and code. The way these antivirus programs go about this task is actually quite simple. The program will receive a list from its publishing company every day or at some other predetermined schedule. This list contains all known code and files that are malicious software. The antivirus software then looks at every piece of code that attempts to come into the computer. New files and code can come from all different places so this antivirus software analyzes threats from a variety of sources: from user input, coming off the internet, or even a file that is downloaded. There are also measures to protect against software that is not on this list. This could be brand new malware that has not yet been identified by the virus protection software publisher. The software will analyze the code to match it up with known malware as part of its typical security protocols. When the program does this and doesn’t have the code on its list, it has a few tests or procedures it can do to determine if the code is malicious. One thing it can do is look at different code fragments from the file and sees if they are close to or resembles any known malware code. If it does then there is a good chance the file you’re trying to bring onto your computer is malicious and the protection software will probably alert you and suggest you don’t open or download that file.

There are some decisions you have to make in regards to your virus protection software. The level to which you are protected will have some consequences on the speed and performance of your system. If you set the levels of protection to their maximum setting, the time you spend on your computer, particularly on the Internet will significantly increase. You have to decide the balance you want to strike between performance and protection.
