Windows 7 USB/DVD download tool

Posted by Awinish on July 9, 2012


My system’s OS was corrupt due to virus attack & i was helpless, because of malfunctioning of my DVD(Blu Ray drive) drive. I decided to buy another DVD drive of the same model, but found its too expensive for the my pocket. My laptop is Sony Vaio & parts of the Sony vaio are too costly. Since, the DVD drive on my system is rarely used & spending money just for installing OS, i was not comfortable to spend the money. Also, if these DVD drives are not been used, you never know how long they will function & requires you to empty your pocket.

I decided to search online what others used to do, when they are into similar situations like me. I found there are options available to install OS using USB/Pen drive. I found a cool utility named Windows 7 USB/DVD download tool which can convert ISO image to a bootable image on the USB drive & the same USB drive can be used to install OS. The utility is very simple & it worked flawlessly for me during conversion of windows 7 ISO to USB bootable image. I also find the tool can also create a bootable Disc too from ISO file.

Steps to create a bootable USB drive are:

  • Download & Install the Windows 7 USB/DVD download tool
  • Open the tool by clicking on it.
  • Locate the ISO file of the OS needs to be converted by clicking on the Browse button.
  • Click Next.
  • Connect the USB device. Make sure it is at least 4 GB, if the selected OS is windows 7.
  • Choose a media type by clicking on the USB Device.
  • You will see USB device appears.
  • Finally, click on copying & once done you are ready to use for the OS installtion.

Note: You need to enable boot from  USB or External devices in Bios on the system loaded with new OS.

Internet Explorer 9 blocks 99% malware attacks: NSS Lab study!

Posted by Awinish on August 19, 2011


Internet Explorer 9 blocks 99% malware attacks: NSS Lab study! 

IE9 continues to protect consumers

 With one third of internet users in Asia-Pacific alone becoming victims of threats like malware, the need for online security is more relevant than ever. To address these online concerns, Microsoft created their latest browser Internet Explorer 9, which provides a safe, secure yet beautiful and speedy browsing experience. Today, NSS Labs released two reports which show that SmartScreen feature in Internet Explorer continues to offer industry leading protection against socially engineered malware. As per the report “Internet Explorer 9 blocks an exceptional 99% malware. 96% of the live threats were caught with SmartScreen URL reputation in IE9, and an additional 3.2% with Application Reputation.”

What’s more, since the October 2010 NSS report, the average time taken by SmartScreen filter to block a threat has gotten 28% faster, if Application Reputation is considered, then the average time has improved by 85%. The graph below compares the test results from various browsers and shows that Internet Explorer blocks 5X more malware than competitive browsers.

 

 

 

 

 

 

 

 

 

 

The other reports looked at socially engineered malware targeted towards people living in Asia Pacific region and in Europe. As you can see below, in each region the results remained consistent – Internet Explorer 9 maintains a lead in protecting users from live threats.

 

 

 

 

 

 

 

 

 

 

* You check out the entire web browser security report by NSS Labs by clicking here: https://www.nsslabs.com/assets/noreg-reports/2011/nss%20labs_q3_2011_browsersem%20GLOBAL-FINAL.pdf.

It is no surprise that a browser is the first line of defense against attacks from the web and it plays an important role to help keep you safe online. Internet Explorer is designed with your security and privacy in mind. The new browser has a robust set of built-in security, privacy, and reliability technologies that helps keep consumers safe and their browsing experience virtually uninterrupted. With IE9, we have introduced new functionalities like Tracking Protection, Tracking Protection Lists, ActiveX Filtering to name a few. IE9 makes browsing the web even safer & protected experience from here on.

IE9 has received positive feedback from consumers globally. As of today, Internet Explorer 9 has over 18% usage share worldwide on Windows 7. You can download Internet Explorer 9 to see how you can enjoy a more beautiful – and trusted web!
