Anti-Virus

Antivirus or anti-virus software is used to prevent, detect, and remove malware, including but not limited to computer viruses, computer worm, trojan horses, spyware and adware. This page talks about the software used for the prevention and removal of such threats, rather than computer security implemented by software methods.

A variety of strategies are typically employed. Signature-based detection involves searching for known patterns of data within executable code. However, it is possible for a computer to be infected with new malware for which no signature is yet known. To counter such so-called zero-day threats, heuristics can be used. One type of heuristic approach, generic signatures, can identify new viruses or variants of existing viruses by looking for known malicious code, or slight variations of such code, in files. Some antivirus software can also predict what a file will do by running it in a sandbox and analyzing what it does to see if it performs any malicious actions.

No matter how useful antivirus software can be, it can sometimes have drawbacks. Antivirus software can impair a computer's performance. Inexperienced users may also have trouble understanding the prompts and decisions that antivirus software presents them with. An incorrect decision may lead to a security breach. If the antivirus software employs heuristic detection, success depends on achieving the right balance between false positives and false negatives. False positives can be as destructive as false negatives. Finally, antivirus software generally runs at the highly trusted kernel level of the operating system, creating a potential avenue of attack.

Computer Virus

To aid the fight against computer viruses and other types of malicious software, many security advisory organizations and developers of antivirus software compile and publish lists of viruses.

The compilation of a unified list of viruses is made difficult because of naming. When a new virus appears, the rush begins to identify and understand it as well as develop appropriate counter-measures to stop its propagation. Along the way, a name is attached to the virus. As the developers of anti-virus software compete partly based on how quickly they react to the new threat, they usually study and name the viruses independently. By the time the virus is identified, many names denote the same virus.

Another source of ambiguity in names is that sometimes a virus initially identified as a completely new virus is found to be a variation of an earlier known virus, in which cases, it is often renamed. For example, the second variation of the sobig worm was initially called "Palyh" but later renamed "Sobig.b". Again, depending on how quickly this happens, the old name may persist.

My Experience In Public Speaking Class Part 2

Group Discussion

In group discussion, I learn to share ideas and opinion with my group members. I also learn to develop my own idea. Doing a discussion with other people also teach us to tolerate with each other.


Inpromptu Speech

We have to speak spontaneously in front of the class. I learn to think fast to find the idea for my speech. This time I feel a little bit nervous because we cannot prepare any text. I learn how to speak without preparing text in this task.


Forum

This is the task that I really cannot forget. It was the most difficult task for me and my friend. Even we were quarrelling with each other to finish this assignment. We cannot do a rehearsal for the forum because we manage to finish it in the last minute. I learn how to do teamwork with my friends and I feel happy to work in group although sometimes we don't really get along with each other.

My Experience In Public Speaking Class Part 1

Informative Speech

This is the first assignment I got in this class. I got the opportunity to tell my classmate and lecturer my background and about my life. I feel so happy because I can share my experience with them. I learn to throw away my nervous to speak in front of the class.

Persuasive Speech

I do this task with my friend, Awie. We decided to use pudding as our product. We also have to make promotion for this product. For three days I don't get enough sleep. We make business cards and label for packaging for our product. The capital is small but the profit is high. I feel so happy doing this task.

If You Are The TV Producer

The primary role of a television producer is to allow all aspects of video production, ranging from show idea development and cast hiring to shoot supervision and fact-checking. It is often the producer who is responsible for the television show's overall quality and survivability, though the roles depend on the particular show or organization.


Some producers take more of an executive role, in that they conceive new programs and pitch them to the television networks, but upon acceptance they focus on business matters, such as budgets and contracts. Other producers are more involved with the day-to-day workings, participating in activities such as screenwriting, set design, casting, and even directing.


In television, there are a variety of different producers on a television show. A traditional producer is one who manages a show's budget and maintains a schedule, but this is no longer the case in modern television. In fact, nowadays a producer is almost synonymous with a writer.


There are several type of television producer :


- Executive Producer

- Co-Executive Producer

- Supervising Producer

- Coordinating Producer

- Co-Producer

- Consulting Producer

- Associate Producer

- Chase Producer

- Segment Producer

- Line Producer

- Field Producer


If I am the television producer, I want to produce a comedy show. It will be in the concept of competition and reality show like 'Raja Lawak'. I want to name the show 'HAHAHA!!!'. This is because I really like comedy show.
