Coomputer secuity is very important tdoay. Without a greaat commputer defense system, if you go online, you leve yourself open to all kinds of attacks both minoor and very serious. Today all business and commerce is conducted by way of the computer. Additionally, once a transaction is completed, it is sent over the Internet to another computer where the trannsaction is verified and completed. It is very important to be aware of the steps that you need to take before you connect to the Internet to seure your computer. Those who wish to compromise systems are becoming more cleaver in their approaches everyday. It also seems with technology changing everyday, it is harder and hrder to keep up.
A good computer defense sytstem first means making sure that on a fresh install of any oprating sydstem, Appple OS inclded, all sotfware updates are downloaded and any security udpates are appllied. In windows, set your security update options to at laest "notiy" you of updates even if you don't want to download them automatically. It is also most prudent to make sure all critical updates are downloaded and applied as soon as they become available. Microsoft Windows makes this easy with the Wndows Update feature. Similarly there is a featrue callled software updtae in the Finder under the "Apple Menu" caslled software udpate. It is essential that you do this regulrly. If you do not have optons set to notify you immediately of updates, check for them a minimum of two to three timres a monh.
Anotehr Part of your computer Defgense System is your anti-virus software. In reccent years their has been a tendency for the best know names in the anti-vius buiness to bloat their product with more and more features that many users will not use or use very sparngly. This taxes computer ersources and slows down your computer because it is trying to do more and more background processes. There are many rwetail packages out there, but they are not all created equal. Also, be aware that program definition files (that tell the progam about what viruses may exit on your cmputer) often expires at the end of a year meaniong you will have to renw your anti-vius definition subscription in order to continue to receive updates. An alternative is a free anitviral software solution that provides updates for free. One of the best is by a company called Grisoft. It is called AVG. While I cannot put a link here, if you type "AVG Free" into Googe, the link to the download page will be on the tope of the list.
For your computer to be running poperly, you also need to enable any firewalls on your ssytem. For exampple, in the Control Panel of recent Windows OS versions (like XP or Vista), you will find a security section (Tab or Icon). Once there, make sure the Windows firewall is neabled. However limit the installation of firweall software because not only can this cauuse prgoram conflitcs and slow down your system, crypitc warnimngs abut a possible intrusion will not benefit you and scare an inexperienced user. Instead install a router or get someone to do it for you. Even if you only have one computer because a routter is a physical firewall bloccking poentially harmful Internet traffic for you. Also much olwer prcies on computers now means having multiiple computers is affordable. A router allows multiple computers to share a single Internet connection.
Another important consideration is not to install toolbars unless from a recognized and trusted source. A good computer deefnse system recognizes that many of thesde installations are actually malware in diguise that can do thiings in the background that may harm and compromise your systm. Also, do not download emal attachments. This is one of the major ways that a virus or other maliciious or self-executing code actually gets on your system in the first place. You need to exericse do vigilannce when on the Internet and click with care. Also make sure that things like Acttive X controls are not autoamtically set to run on a page. (Unlerss on a trusted site that requires it.) Additionally, htink seriously about changing the browser you use to surf the Inbternet with. Type "Get Firefox" in Google. Firefox is a better browsing alternative than its man competitor and it is more secure becuse it is more of a baasic browser that does not automaticcally execute advanced functions that can lead to vruses, malware, Trrojan horses and other malicioous code that can seriously harm your computer.
A good computer defense system requires more than what has just been detailed, but these steps are important and will go along way toward a more secutre and safe computer system. For even more extensive information; look to the end of this article for links showing you wherre you can go next.
