Google Now Censors the priated sites like priatebay and many more

According to torrentfreak site  , Google has been filtering “piracy-related” terms from its ‘Autocomplete‘ and ‘Instant‘ services.
Google users searching for terms like “torrent”, “BitTorrent” and “RapidShare” will notice that no suggestions and search results appear before they type the full word. As a consequence, there’s sharp decrease in Google searches for these terms.

Searches referring to torrent sites such as “thepiratebay,” “the pirate bay,” “isohunt,” “torrentreactor,” “btjunkie,” “kickasstorrents,” “sumotorrent,” “btmon,” “extratorrent” and many others are now excluded from ‘Autocomplete‘ and ‘Instant‘. Interestingly, the full url “thepiratebay.org” is still offered as a suggestion. 

The new list further includes several cyberlocker websites that were previously left unfiltered, such as “4shared,” “filesonic” and “fileserve.” Although Google doesn’t censor the content of the websites in question, the Google searches for the affected terms drop significantly .

Despite of the criticisms from various groups and peoples , Google said it will continue to filter the sites and they will expand the censor list in coming years !!

How does facebook Self XSS works ??



If you are a facebook user , you may have definitely came across video posts on your wall that have a  title and an innocent thumbnail but upon clicking, the link redirects  you to a scam website. 

How does those links came on your wall ??? , Does that particluar person's account is hacked ?? or does he his PC contains virus which is posting those malicious links on his friends wall ??? 


Matt Jones, who works with the Data & Security team at Facebook, walks us through the various type of scams that happen on Facebook.com and why do they happen?? . Most scams require Facebook users to copy-paste some JavaScript code into the browser's address bar and as soon as they do that, the rogue post is automatically published to the walls of all their Facebook friends.

Facebook Self XSS 


According to Matt, Google Chrome and Safari are the only browsers that are susceptible to this kind of cross-site scripting (XSS) vulnerability while IE and Firefox are relatively safe. And since the malicious JavaScript code is often hidden inside Flash videos, Facebook isn’t able to detect it.

TOEFEL ESSAYS ( Has television destroyed communication among friends and family?)


Has television destroyed communication among friends and family?

This essay was written by me (Erin) and has 653 words. Even though this essay is relatively long, I wrote it in under 20 minutes. Your essay should have 250-500 words.

Estimated TOEFL Essay score: 6.0/6.0
Television is undoubtedly one of the most powerful means of communication in the history of humankind, rivaled only by such other forms of communication as the Internet, the telephone, movies, and, of course, simple, low-tech speech. Television, with its wide availability and rich media with image and sound, is difficult to ignore and even seductive in its appeal. Television is as much a part of our lives as are our meals, work, or school; studies consistently show that the average American child spends almost as much time watching television as she does in school. Furthermore, because television is so rich in its media, it often requires our full attention or is more attraction to us than are our daily lives. Naturally, the more time one spends watching television, the less time she has with her family and friends. Thus, we can clearly see why some have claimed that television has been harmful for communication among family and friends. However, I believe that, while television has been somewhat harmful in its effects, it has hardly "destroyed" communication among family and friends for most people, although for some, this may be true.
Most people much prefer spending time with their families and friends to spending time watching television. Television is of course an important part of many people's lives, but most people would gladly choose family and friends over television were they given the choice. Furthermore, most educated people are aware of the deleterious effects of too much television and either avoid excessive time watching television, or actually do not enjoy it. I, for example, after a long day at work, would much rather spend time talking with my wife and playing with my children than I would watching some unrealistic portrayal of life on television. For me and my family, our time together is precious and beautiful, and could never be replaced or hurt by television.
Furthermore, the effect of television is simply not so great that it could be said to have "destroyed" communication among family and friends. Granting that communication among family and friends in industrialized countries has decreased in recent years, it might be tempting to blame this problem on television since its rise roughly coincided with the decrease in time we spend with our families. However, I believe this situation is more likely due to increased pressures relating from work, school, and the economy. In my case, for example, I find that my pressures from work are so great that I must often sacrifice time at home so that I can meet the challenges of running my own business. Many of my friends are in similar situations--my best friend, for example, has just finished law school, which took about sixty hours a week of his time. In a word, people nowadays have very little time for anything, but television is not the cause--it is increased desire to succeed.
In some situations, however, television has surely contributed to a decrease in communication among family members. In my childhood in the countryside, I often saw parents and children watching television for hours on end, rarely speaking with one another. It seemed for them that television was a way to escape from their sad, miserable existence. However, even in this case, I would say that television merely contributed to the bad situation, but did not cause it; were television not existent, surely these people would have found other escapes, alcohol or gambling, for example. In other words, people always find a way to do what they want to do.
In short, I do not believe that television has destroyed or even harmed interpersonal communication among most people. Most people realize that television is merely a temporary diversion and do not use it to replace interpersonal communication. I believe that the damage attributed to television is greatly exaggerated and that such damage is most likely attributable to other more powerful social factors.

TOEFEL ESSAYS (How do movies or TV influence our behavior?)


How do movies or TV influence our behavior?


6.0/6.0
This is a unique essay; it is written in a more literary style than the traditional "cut and dried" approach of most essays. It is refreshing to read such essays!
Hesitating I enter my house, the light outside is dimming and the shadows make everything appear unfamiliar. I know that my husband has not returned from work yet, simply because his car is not in the garage. I am alone. I carefully check all the rooms, almost expecting something to happen suddenly. I hold my bag in my hand as if it were a weapon. After the whole house has been declared “clear,” I start to breathe normally again and a smile appears on my face as I realize, once again, how a simple movie seen at the cinema a week earlier can modify my actions.
Sometimes I wonder if I should watch TV, with all its shows that make me wonder whether I exercise enough, whether I am slim enough, or whether I treat my pets with the care they deserve: am I really concerned about their mental health??? Not to mention the hundreds of commercials that try to make me believe I need a water purifier to remain alive since the water I am currently drinking is heavily polluted! And countless are the times when I have heard people talking by quotations learned from movies… We need to watch shows and films to know what to say, how to be, how to act. We are so addicted to all this that it almost seems like we cannot think on our own.
I cannot help thinking about what happened to me some days ago, an example that clearly shows what kind of power TV has over people. My husband and I were in a restaurant when I heard my young neighbor pronouncing violent words in a low angry voice. Surprised, I turned to better understand the situation and I saw that he was holding a fake military device and was acting as if he were filming a war movie. I am sure that if I had been a little be more updated about this type of movie, I would have recognized what he was saying as a quotation. Now, I wonder if he uses such a language also with his friends and with his parents, if he is aggressive, and if so, whether his attitude has really nothing to do with what he watches on TV.
That same evening on the way home I saw two cars stopped one next to the other at a traffic light and as soon as the light turned green they started racing, in the middle of town. In this case not even a major knowledge of movies and TV programs would have helped me: there are just to many of them on the market showing the exact same thing: people racing with cars.
I am sure that everybody, if asked, could easily list many other examples of how TV and movies can modify our behavior and therefore our life but, I wonder, if we will always be able to draw the line between a TV show and real life, between what they make us think we want and what instead we really need and are and believe.

TOEFEL ESSAYS ( If you could change one thing about your hometown, what would it be?)


If you could change one thing about your hometown, what would it be?


Estimated score: 6.0/6.0:
Everything in the universe is in constant change. And everything needs continual improvement if the ever changing and increasing demands of humankind are to be met. If I am ever given the chance to change one important thing about my home town, it would be internet service. Needless to say that nothing generally revolutionized the way we live as internet in the past decade. Thus, an improvement in this vital service would mean an even more, unheard betterment to the people in my home town.
It is said that information is power. True saying indeed! I can envision how everything in my home town could improve dramatically if the internet service in it were made free, fast and staying out there like electricity, telephone or water all the time. One thing, a fast free and reliable internet service could improve in my home town is the way people work. If there is a this said service people in my home town must not necessarily commute to a far place to do their job. This in turn would mean less traffic jams, spacious work place, more time for family and recreation and so on.
The way people learn would be another important thing that a fast, free and reliable internet service could better in my home town. People will have the chance to go through tremendous and different information resources in a very small amount of time. They, apparently will also take less time to share it. This assures a more fulfilled life for my home town people.
Since its advent, internet touched every part of our life. It in a dazzling way improved the way we do business, learn and communicate. A change in internet service implies good way of living for every one in my home town.

TOEFEL ESSAYS ( Do you support building a factory in your hometowm?)


Do you support building a factory in your hometown?


Estimated score: 6.0/6.0:
This essay follows the standard pattern of a good TOEFL essay--it has simple, clear points that are supported with examples. I particularly like the way the writer was very specific about how water pipes would have to be replaced; this detail makes the essay seem well planned and makes its writer seem insightful.
TestMagic has edited this essay to make it score 6.0. The original essay did not mention the name of the town, leading to a decrease in vividness.
I am from Arroz e Feijao, a small town in the northeast of Brazil. Building a factory in there will bring a lot of advantages and disadvantages, but I believe that Arroz e Feijao will mostly benefit from the building of a new factory because it is largely populated by poor people and the factory would bring many benefits to this small town. However, of course, a factory has disadvantages as well.
As you know, factories usually bring pollution. If this factory is not managed very effectively and efficiently according to specific rules, it's prone to polluting the local air and water. What's more, factories usually make noise. Beside clean drinkable water and fresh air, an ideal community should be quiet. If the factory cannot maintain this situation to the community, it will not last long. A factory that is too noisy or pollutes too much will eventually be relocated to a new area.
On the other hand, a factory could bring a lot of benefits to the community. So I would support the plan to build a factory to my community for all the reasons I will describe below.
First of all, the factory's construction will surely improve the local infrastructure. To run smoothly, the factory will have to have a steady, reliable supply of water and electricity. Some old pipes will be changed, and some facilities will be renovated. The residents' living standard get improved as a result of these widespread changes, an important benefit in Arroz e Feijao, where many people do not have access to clean water.
Secondly, to make the employee commute more convenient, the local roads will have to be rebuilt and broadened, resulting in improved public transportation. The town's residents can take a public bus to go shopping or go to work. As a result, air pollution and fuel consumption might be reduced.
Most important, a factory's establishment will bring up a lot of employment opportunities for the community. A factory need experts from various fields. The residents can take just a few minutes to go to the factory to work. So, the local residents can get great benefits from this factory.
Generally speaking, I agree with the plan to build a factory near my community. If the factory can be managed successfully, the factory and local residents can have mutual benefit.

TOEFEL ESSAYS (Compare knowledge )


Compare knowledge gained from books with knowledge gained from experience.

6.0 Sample
People always are learning and practicing through their whole lives. From reading words in text book such as toy, car, train etc., people have the concept and ideas. They further understand the actual meaning of these words by playing toys and riding or driving cars, trains etc.
Education (books) and experience are the main two channels for People to gain their knowledge. Each play different roles for people. In my opinion, knowledge from experience is more important than that from books.
Experience first can prove if the knowledge form books are true or false. Textbooks are very wonderful in teaching people essential principles, how is the world looks like? what is the basic law of change of people and things? We can learn a lot through primary school, secondary school until university. However, people can only understand the really meaning of those form books and justify them if they are right through practices. A few hundred years ago, people learnt from text book that the earth was flat. However scientists found that was wrong through observations and measurement.
The knowledge from experience can improve and advance 
the world and our society. As books have limitation, they only teach us the what people found in the past. The knowledge from the books are constrained to the certain conditions and environment. For example, mould and tools design for plastics industry, the university course only taught me very simple cases, most knowledge are obtained from various different and complicated cases in my career.

There are a lot new inventions and new products which could not be found from textbooks. Our society and world are developed through continuous practices, those knowledge, never found in books, such as internet, e-business etc. are all developed through new practices.
"The truth comes from practices and experience", people are continually discovering new things and assessing the creditability of the knowledge written in books. The knowledge from experience help us much more than those from books.

Top 10 Ways to Defend Against Malware and Trojans



Top 10 Ways to Defend Against Malware and Trojans 



Although hackers never stop developing new tricks to commit fraud and 
steal identities, consumers can take some measures to safeguard their 
systems. All it takes is a combination of good security software and a 
commitment to following basic safety rules. 

1.  Protect your computer with strong security software and make 
sure to keep it up to date.  Many security software's provides trusted PC 
protection from Trojans, hackers, spyware, and more. Its integrated 
anti-virus, anti-spyware, firewall, anti-spam, and anti-phishing work 
together to combat today’s advanced multi-faceted attacks. It scans 
disks, email attachments, files downloaded from the web, and 
documents generated by word processing and spreadsheet programs. 

2.  Use a security-conscious Internet service provider (ISP) that 
implements strong anti-spam and anti-phishing procedures.  

3.  Enable automatic Windows® updates or download Microsoft® 
updates regularly to keep your operating system patched against 
known vulnerabilities. Install patches from other software 
manufacturers as soon as they are distributed. A fully patched 
computer behind a firewall is the best defense against Trojan and 
spyware installation. 


4.  Use extreme caution when opening attachments. Configure your
anti-virus software to automatically scan all email and instant message
attachments. Make sure your email program doesn’t automatically
open attachments or automatically render graphics, and ensure that
the preview pane is turned off. This will prevent macros from executing.
Refer to your program’s safety options or preferences menu for
instructions. Never open unsolicited business emails, or attachments
that you’re not expecting—even from people you know.


5.  Be careful when engaging in peer-to-peer (P2P) file-sharing.
Trojans sit within file sharing programs waiting to be downloaded. Use
the same precautions when downloading shared files that you do for
email and IM. Avoid downloading files with the
extensions .exe, .scr, .lnk, .bat, .vbs, .dll, .bin, and .cmd. Anti-virus
software and a good firewall will protect your system from malicious
files.

6.  Download the latest version of your browser to ensure that it is
also fully updated and utilizes the latest technologies to identify and
filter out phishing sites that can install Trojans.

7.  Use security precautions for your PDA, cell phone, and Wi-Fi
devices. Trojans arrive as an email/IM attachment, are downloaded
from the Internet, or are uploaded along with other data from a desktop.
Cell phone viruses are in their infancy, but will become more common
as more people buy phones with advanced features. Anti-virus
software is available for PDAs and cell phones.

8.  Configure your instant messaging application correctly. Make
sure it does not open automatically when you fire up your computer.
Turn off your computer and disconnect the DSL or modem line when
you’re not using it. Beware of spam-based phishing schemes—don’t
click links in emails or IM.

9.  Be certain a web site is legitimate before you go there. Use
software that automatically checks this, such as AccountGuard from
eBay and ScamBlocker from Earthlink. You can also check the validity
of individual web addresses (URLs) with a WHOIS search such as
http://www.DNSstuff.com.

10. Back up your files regularly and store the backups somewhere
besides your PC. If you fall victim to a Trojan attack, you can recover
your photos, music, movies, and personal information like tax returns
and bank statements.
