I recently had a magazine of Symantics and have read about how protection is done by an antivirus software in the simplest thought. I would like to share it with you all.

The classic mechanism for detecting and stopping threats is Blacklisting though the use of Virus Signatures. Which is i guess the primary reason why we have to update our antivirus software regularly. It is analogous to using a fingerprint matching to catch criminals. In order to for a virus to be recognize, it needs to be in the virus signature, if not it will not be considered as a threat. This works well on those virus that had been already discovered. But how about those new invented viruses, well in this situation blacklisting mechanism isn't effective anymore.

Here come Heuristic Technology, it is examining the attributes of files on disk to check for suspecious characteristics. For the analogy, if you see a person wearing an angle lenght coat in the street during summer with something obviously concealed underneath, we usually identify them as "suspecious". Any suspecious file can still be detected eventhough it is not in the virus signatures.

The last line of defense beyond blocklisting and heuristics is, Behavioral Protection Technology. This involves monitoring actively running software and network streams for behavioral patterns that could be malicious. In this approach, it is possible to identify entirely new threats or classes of threats by examining their behaviour. It can catch entirely new and unknown malware that has bypassed classic, finger-print antivirus protection and heuristic protection.

Global Warming is a major problem today that needs all of our attention. Others may not feel its effect today, but studies show that its effect is getting worst. It has been a long time since my teacher in college opened my eyes on the effects of Global Warming. I guess the best thing that i have done since then was "walking instead of riding transportation vehicles". It is a fact that almost all people today are in a hurry that they ride cars or any transportation vehicle even if the place where they are going is just near. Others are just becoming too lazy to walk a few kilometers. Even our teacher that time made it a practice to lessen the use of his car. And I personally see it with my own eyes. We are all aware of the effects of the smokes being emitted by vehicles, it adds to our global warming problems. Maybe this is just a simple task but it would be something that everyone should look into. Aside from helping in our global warming problems, walking also gives us a lot of benefits like being a form of exercise and saving fuels(if you own a car). Until now, i am doing this not only for my own good, but also as a sign of showing that I value Mother Earth and everyone that is in it, including YOU!
