Study reveals that Internet Explorer prevents 95pct of malicious activity


NSS labs had announced the results about the best browser which can protect against leading forms of malware.The tests carried out on different browsers like Microsoft Internet Explorer, Google Chrome, Mozilla Firefox and Apple Safari,how far they can protect users from bank fraud, password theft, fake antivirus scams and click fraud.These results were announced on yesterday.


Results highlighted that Internet Explorer offered users significant advantages pertaining to overall malware protection, preventing 95 percent of malicious activity; Chrome blocked only 33 percent, Safari and Firefox less than 6 percent each. Click fraud malware was blocked at a significantly lower rate by 3 out of the 4 browsers tested. Here again, the results highlighted that Internet Explorer continued to do better than the others by blocking 96.6 percent of click fraud activity; Chrome managed only 1.6 percent, Firefox and Safari blocked only 0.8 percent and 0.7 percent, respectively. Block rate scores were calculated as 10-day moving averages.


“Given Chrome’s prominence and increasing market share, we predict ongoing increases in click fraud unless Google takes serious steps to improve its click fraud protection,” said Dr Stefan Frei, Research Director, at NSS Labs

It was found in the tests that click fraud scammers managed to rake in revenue for both fraudsters as well as legitimate ad networks, by making counterfeit ad click-throughs look genuine.

Some of the key findings of the report revealed that click fraud by itself causes minimal direct harm to the typical end user, since the ultimate target is the ad buyer. What actually harmed consumers and corporate users was the additional malware that came as a by-product of click fraud installation. Click fraud the detection rate of Chrome was 1.6 percent, Firefox 0.8 percent, Internet Explorer strikingly high at 96.6 percent, and Safari 0.7 percent. Further, the report highlighted that certain services may help ad buyers identify click fraud. However, service contracts with ad networks may contain clauses that restrict ad buyers’ ability to recover damages for click fraud.

Interestingly, the report revealed that the average lifespan of a click fraud URL was 32 hours with over 50 percent of them expiring within 54 hours. NSS Labs' study was performed over a period of 175 days (from December 2, 2011 to May 25, 2012) about the protection capabilities of Google Chrome, Mozilla Firefox, Internet Explorer, and Safari. Each browser was tested with all available updates installed on identical virtual machines running Microsoft Windows 7.

Understanding Trans Fats and Their Impact on Heart Health: Unveiling the Science and the Indian Scenario

Trans fats have become a topic of concern in recent years due to their detrimental effects on heart health. These fats, predominantly found in processed foods, pose a significant risk to cardiovascular well-being. In this blog post, we will explore the science behind trans fats, their impact on the heart, shed light on the concerning scenario in India, and discuss common sources of trans fats in our daily diets. Additionally, we will provide practical tips on how to avoid trans fats and make informed choices for a healthier heart. Part 1: The Science Behind Trans Fats and Heart Health What are Trans Fats? Trans fats are artificially created fats formed through a process called hydrogenation. During hydrogenation, liquid vegetable oils are treated with hydrogen gas, leading to the formation of partially hydrogenated oils. These oils contain trans fatty acids, which alter the structure of the fat molecules. The Science Behind Trans Fats and Heart Health : 1. Cholesterol Imbalance : Trans

Intel 2Q profit jump reflects healthy PC demand

SAN FRANCISCO - Worried that the ailing U.S. economy has spilled abroad and hurt global PC sales, investors had subdued expectations for Intel Corp. in the second quarter. Intel is the world's largest computer chip maker, and its fortunes rise and fall with swings in PC demand. The Santa Clara-based company responded Tuesday with a 25 percent jump in profit and record sales in the quarter, fueled by strong sales of processors for laptop computers. The results easily beat analysts' expectations and reassured Wall Street that Intel is weathering the dreary domestic economy thanks to its broad international reach, a robust product lineup, and a manufacturing advantage over smaller rival Advanced Micro Devices Inc. that lowers Intel's cost of making chips. Intel Chief Executive Officer Paul Otellini said demand for Intel's chips remains strong "in all segments and all parts of the globe." Three-quarters of Intel's business is outside the U.S. Intel shares rose

India's Vulnerability to Inflation and Currency Depreciation: Understanding the Major Drawbacks

India, like many countries, faces various challenges that can make it vulnerable to inflation and currency depreciation. Inflation erodes the purchasing power of the currency, while currency depreciation can lead to higher import prices, affecting the economy. In this blog post, we will explore some major drawbacks that leave India vulnerable to these economic issues. 1. High Dependence on Imports India imports a large quantity of crude oil, gold, and other commodities, making it susceptible to fluctuations in global prices. Any sudden increase in the price of these commodities could lead to higher fuel prices, which can then drive up transportation costs and ultimately push prices higher across the economy. In addition, the cost of gold imports can affect the current account deficit and the value of the Rupee. Example: In 2018, global oil prices increased significantly, leading to higher fuel prices in India. This impacted inflation and the value of the Rupee as India is heavily depen

Japan's Work Culture: A Comprehensive Examination

Japan's work culture is often lauded for its dedication, efficiency, and unwavering commitment to productivity. However, beneath this veneer of unwavering diligence lies a darker reality – a culture that has normalized overwork, perpetuated a pressure to conform, and left little room for personal well-being. The prevalence of karoshi, or death from overwork, is a stark testament to the detrimental effects of Japan's work culture. An estimated 10,000 people succumb to karoshi each year, highlighting the alarming consequences of excessive work hours and the relentless pursuit of productivity. Zangyo, or overtime, is deeply ingrained in the fabric of Japan's work culture. Employees are often expected to work long hours, often extending beyond their official working hours. This relentless pursuit of productivity comes at a heavy price, leading to burnout, a state of emotional, physical, and mental exhaustion. The pressure to conform in Japanese society extends to the workplace,
