Computer Safety - Use Computer Security Programs to Surf the Web Without Fear

Computers have become an integral part of our lives. It is impossible to imagine a day in our lives where we do not check our mail accounts, social networking accounts or otherwise surf the web for news or entertainment. However, it is very dangerous to surf the web without securing your computer from all the malicious programs and elements on the web today. Read ahead and find out ways to keep your personal computer secure when surfing the web.

A- Antivirus programs

Sophisticated anti virus programs are available in the market today. Most paid programs offer regular for at least one year from the date of purchase for free. It does not cost a lot to renew the same. A fully functional anti virus program is enough to protect your computer from the most harmless to the most dangerous viruses. Antivirus programs form the last line of defense. Even if a virus or bugware infects your computer after overcoming all other protective programs, the anti virus program will scan and remove such infections.

B- Firewall

Most reputed anti virus programs come with a customized firewall as well. However, most individuals simply ignore the firewall because it makes it difficult to operate some programs like torrent software programs. However, the benefits that firewalls offer far outweigh the minor problems that one has to face. The firewall acts as the gatekeeper for your computer. Nobody will be allowed in and nobody will be allowed out (we are talking about data here) unless the gatekeeper i.e. the firewall permits. If you still are not comfortable using customized firewalls, just make use of the basic firewall offered by Windows XP and onwards.

C- Safe surfing

No program will keep your computer free of infections if you do not surf the web safety. The computer may be the smartest device invented by man. However, using your common sense is a must to keep your computer safe. Downloading files obtained from unknown persons is a strict no-no. You must follow certain basic common sense rules to keep your computer safe.

Most Important Computer Security Programs

The web can be full of hazards these days as hackers and malware developers strive to get important information such as credit card information, user IDs and passwords to paid subscription websites, social networking sites, e-mail accounts, and other personal data. Other people simply want to wreck havoc on a multitude of computers connected to the Internet for entertainment purposes. Fortunately, there are a number of computer security programs that you should install immediately so that you can prepare for the threats.

Microsoft Security Essentials

Microsoft Security Essentials is Microsoft's first attempt to combat viruses floating around the net. It is presented to be extremely easy for people to setup and runs in the background without eating up too many resources, making it an ideal solution even for older computers that do not have much RAM. The best thing about this software is that it is free for all licensed Windows XP users and above. Virus definitions update every few days so it should keep your system secure enough especially when combined with the Windows Firewall for blocking attacks and the Windows Defender for combating spyware.

Secunia PSI

Unlike other security applications, Secunia PSI doesn't tackle or detect any threats that are within the system or on the net. In fact, it doesn't attempt to make any modifications of the computer itself. Instead, Secunia PSI scans all of the applications that are installed in the system and checks for any vulnerabilities. Some programs where hackers take advantage of vulnerabilities include many of the Adobe software particularly Adobe Reader and Adobe Flash. Other third-party browsers are checked for vulnerabilities as well. If any vulnerabilities are detected, the information regarding the vulnerability is shown. In addition, a link to the latest version of the application that patches this vulnerability is supplied if provided by the developer, making it easy for people to keep their most important programs up to date.

CCleaner

At first glance, CCleaner is more of a system maintenance tool rather than a security tool since it specializes in cleaning out all of the junk files in the computer such as the Internet cache of the different browsers and other temporary files. The security aspect of the program can be seen once you start using it to clean up any private tracks that are left behind so that other users won't be able to see. This includes recently open files, cookies, Internet browsing histories, and other links. It can also be used by more experienced users to check what programs will run on startup. If any suspicious programs are listed, you can securely remove those entries to disable the malware's functionality. It also has a registry scanner that can solve problems and improve performance as well.

All of the three programs mentioned above are freeware and should be installed immediately because they do not cause much of an impact in system performance and do not come bundled with any spyware. However, you can improve your security even more by substituting your free antivirus scanner with a commercial product that can do a better job in removing and cleaning malware as well as blocking firewall attacks. Good programs include ESET NOD32 and Smart Security, Kaspersky Internet Security, and other popular commercial tools.

Computer Graphics Programming Revealed

The term computer graphics programming must be broke down to be understood completely. We all have a good understanding of computer- what it is, what it does-and how to use it somewhat efficiently. This article is not going to get into this aspect; the topic is broad and would fill a book.

Instead this article will focus on the graphics part of the title. We will leave the programming for another article as well­-again the topic is broad and requires more space than the one page this article is allowed.

According to Wikipedia, computer graphics is also a broad subject, which can describe anything "on computers that is not text or sound". So we can deduce: graphics are images. It gets more interesting though, when we look at the many ways in which images are captured and created. So, as we move into this topic, it becomes evident that graphics are not simply pictures or images themselves, but it is also a term used to encapsulate how these images are manipulated.

Today computer graphics programming is more popular than ever.

The field of study for computer graphics is sky rocketing. As our culture zooms forward into the 21st Century with new technology appearing almost daily and existing technology improving exponentially, we find ourselves enmeshed in a graphic society. Our movies are more graphically animated than ever before in history-not only because it entrances the viewer but because technology makes it so easy.

In the movie industry we might be familiar with the term "CG". This stands for Computer Generated. This technology allows the ability to create nearly any fantasy scene we can dream up. Movies like 300 create well over 70% of the imagery with computer generated imagery. Interestingly enough, not everyone can even tell the difference. How many of you thought the scenery, or other CG aspects, were real when you saw this movie?

Computer graphic programming exciting

The amazing part of computer graphics is- whatever you can conceive in your imagination, you can likely get it on the computer. There are many programs out there which enable the user to do different things with imagery. Adobe's Photoshop is probably one of the most well known and popular programs for manipulating photos. This program specifically manipulates pixels, the smallest component making up the image of a photograph. Programs such as this one allow us to wipe pimples off our face, get rid of double chins and even cinch our waistlines to produce more attractive results.

This is just the beginning of what is possible with graphics. Look for other articles on computer graphic programming to learn more about graphic potential and the fun things we can achieve with graphics.
