What's the Best Anti-virus Program?
[These days this question is very easy to answer. The ACCC has a site license for Norton AntiVirus that allows you to use it on any personal computer that you own, at school or a home, for no cost. NAV is easy to install and update -- it will update itself if you want to -- and it works great. For more information, see the ACCC AntiVirus Web page. -- Ed.]
Actually, this question is very hard to answer, because I feel the best antivirus program would be one that will rid my system of all viruses. Unfortunately, that doesn't exist. But here are a few that have worked for well for me.
Shareware virus scanners: McAfee: Version 2.27e for DOS, all varieties of MS Windows, and OS/2, at http://www.mcafee.com/, and FProt: Version 2.20 for DOS, at http://www.fprot.com/. Both are shareware and should be registered if you continue to use them. New versions of both are released every three to four months; they can be FTPed from their Web sites. I like them because I can get them fast over the Internet and because they have found and cleaned almost every virus I have encountered except for SMEG.
Commercial anti-virus programs: Two of the best and most reliable commercial programs are Norton AntiVirus and IBM AntiVirus. The programs themselves are not available on the Internet, but the updates that kept them current are:
Norton (at Symantec): http://www.symantec.com/
IBM: http://www.brs.ibm.com/ibmav.html.
Note added 4/98: These days, add Dr. Solomon's, which the ADN distributes at no cost under a site license. For further information, documentation, and downloading, see: http://www.uic.edu/depts/accc/software/antivirus/

About virus
A computer virus is a computer program that can copy itself[1] and infect a computer. The term "virus" is also commonly but erroneously used to refer to other types of malware, adware, and spyware programs that do not have the reproductive ability. A true virus can only spread from one computer to another (in some form of executable code) when its host is taken to the target computer; for instance because a user sent it over a network or the Internet, or carried it on a removable medium such as a floppy disk, CD, DVD, or USB drive. Viruses can increase their chances of spreading to other computers by infecting files on a network file system or a file system that is accessed by another computer.[2][3]
As stated above, the term "computer virus" is sometimes used as a catch-all phrase to include all types of malware, adware, and spyware programs that do not have the reproductive ability. Malware includes computer viruses, worms, trojans, most rootkits, spyware, dishonest adware, crimeware, and other malicious and unwanted software, including true viruses. Viruses are sometimes confused with computer worms and Trojan horses, which are technically different. A worm can exploit security vulnerabilities to spread itself automatically to other computers through networks, while a Trojan is a program that appears harmless but hides malicious functions. Worms and Trojans, like viruses, may harm a computer system's data or performance. Some viruses and other malware have symptoms noticeable to the computer user, but many are surreptitious and go unnoticed

MULTIMEDIA
What is Multimedia?Multimedia is a term that was coined by the advertising industry to mean buying ads on TV, radio, outdoor and print media. It was originally picked up by the PC industry to mean a computer that could display text in 16 colors and had a sound card. The term was a joke when you compared the PC to the Apple Macintosh which was truly a multimedia machine that could show color movies with sound and lifelike still images.When Windows reached about version 3, and Intel was making the 386, the SoundBlaster equipped PC was beginning to approach the Mac in sound capabilities it but still had a long way to go as far as video. The Pentium processor, VGA graphics and Windows 95 nearly closed the gap with the Mac and today's with fast Pentiums, new high definition monitors and blazing fast video cards the PC has caught up with the Mac and outperforms television.There are a number of terrific software packages that allow you to create multimedia presentations on your computer. Perhaps the best and most widely known is Microsoft's PowerPoint. With PowerPoint a user can mix text with pictures, sound and movies to produce a multimedia slideshow that's great for boardroom presentations or a computer kiosk but difficult to distribute.Eventually, in the not too distant future, the digital movie imbedded in web pages will become the presentation delivery system of choice relegating PowerPoint to the dustbins of software. If you have ever browsed a DVD movie disk on your computer you've seen that future.The basic elements of multimedia on a computer are:TextStill imagesSoundMoviesAnimationsSpecial EffectsText, still images and the video portion of movies are functions of your monitor, your video card and the software driver that tells Windows how your video card works. Your monitor is essentially a grid of closely spaced little luminous points called pixels which can be turned on and off like tiny light bulbs. For the sake of simplicity we'll extend our above example to say that the little bulbs can be lighted with a number of colors. Just how close together those points of light are packed is a function of your monitor. The number of colors that the luminescent points can display is a function of the monitor in concert with the video card. (If you're wondering what a video card is, follow the cable from your monitor to your computer.)

Advance power point nagivation
Chances are, most of you have used Microsoft Powerpoint. For the class slides, simple presentations and such we only use the most basic features of the MS product. We are going to explore some of these features. The goal isn’t necessarily to expand our knowledge of Powerpoint but to experiment with some of the forms of navigation discussed in class.
The Scenario:You are a scientist that studies chimpanzees. Last month you witnessed one or more chimpanzees do something that has never been done before. You were tasked with creating an application that details various aspects of that discovery…for some reason you chose Powerpoint as your tool.

multimedia
What is Multimedia? Multimedia is a combination of text, animated graphics, video, and sound delivered to you via some electronic means. We are immersed in it. Its what appeals to me for entertainment; for research.
