Antivirus for Linux

In our virtual world cyber technology has greatly improved in recent years. Internet has advantages and disadvantages of the universe. All the people in the world today knows what is on the Internet! PC with internet access is available in every home. Because of this security was essential. Crippling viruses, trojans ends, spyware and malware has been increased in many advanced technology.

Essential for all PC users to have security features enabled on your PC. To get rid of all Internet threats of malware, some security features such as antivirus, firewall needs. Single window for the virus? Some people choose their operating system Linux as they do not get linux virus, but the fact is that they also get viruses because of modern technology. We can say linux is less chance of viruses. It is good to be a virus for Linux also.

It used to be the case that Linux is not highly targeted by malware authors for two main reasons. Firstly, the general popularity among Linux users at home is not very high. This meant pirate. A small number of potential victims, and thus a low "return on investment" for their efforts

It has always been much more lucrative to attack Windows because of its large customer base. Second, the fact that there are many variations (distributions) of Linux OS virus programmer to create and test the attack code separately for each of them.

Compare this with Windows, where one virus can infect any code that uses the operating system. In recent years, however, these two points have eroded. Firstly, there is a general increase in the popularity of the OS with home users increasingly adopting Linux.

The fact that the major computer retailers such as desktops and laptops are shipping with Linux Dell installed reflects this change. Second, the runaway popularity of easy to use as Ubuntu Linux distributions consolidated the fragmented client base. Unfortunately, this makes it easier for hackers to one piece of viral code, create hit millions of users.

Norton Scientific Reviews: Can Skype, Government Spy on Calls?

Rumor has it that Microsoft Skype could open for "lawful interception" of voice and data communications.

Skype has been known to have complex relationships of peer-to-peer and strong encryption, making it virtually impossible to intercept. But today, the quality of Skype security came under intense scrutiny after the acquisition by Microsoft for its $ 8.5 billion.

According to the spokesman Norton scientific tests, they "with law enforcement agencies as far along as it is technically and legally possible" and can not confirm or deny anything directly.

But recently, hackers are claiming that Skype has made changes to the architecture - changes that make it more convenient for the security forces "legally" could pickup. Skype has denied the charges and insisted that the changes were only to update their system and not to facilitate monitoring.

The suspicion that Skype could have spied on data and voice communications will come from the recent approval of the patent application, Microsoft last year that he was "to silence copy notification of the meeting."

However, the error with this rumor that two years before Microsoft bought Skype, the application of "lawful interception" patent was already in progress. In addition, the patent itself does not really have details on how the technology works.

Meanwhile, Microsoft denies the allegations, claiming that the updates in the Skype network to improve the safety and quality of service and to not allow them to spy.

If Skype can really be used by the authorities silent on this issue could be a tactic of enterprise search can be sure. It is likely that the change of direction has to do something. Prior to its acquisition by Microsoft, this is only a small upstart private if they wish, can refuse to comply with the government data requests. But now that it's part of a larger business and large, it is obviously in a different perspective.

The best bet for Microsoft is a Transparency Report, published as by Google and, more recently, Twitter published. Thanks to this, the public would better understand the details of the applications from entities for the user data from them. In addition, Microsoft also formal guidelines that ask the authorities for them, should be available for data and data types.

Norton Scientific opinion is obtained from a blogger-cum-security expert who keeps a close eye on the technology industry and the trend of malware. This blog is intended to educate the public regarding the benefits and keep malware and anti-virus updated counterparts.

Is Windows 7 Still Vulnerable to Viruses

Windows 7 is an upgrade value provides a user interface super new, but do not expect great improvements in security.

Software company Sophos anti-virus tested Windows 7 integrated anti-virus works by its own system of 10 pieces of the latest malware. Eight of the 10 samples was a success, says Sophos.

"Unfortunately, despite Microsoft's claims, Windows 7 disappointed that previous versions of Windows," Chester Wisniewski, a security consultant at Sophos, in a blog entry. "The good news is that the freshness of the 10 samples that are arrived, 2 would not work properly on Windows 7. "

Sophos results are not surprising: Windows 7 promises compatibility with most software that works on older operating systems like Windows XP. It would make sense that most malware is close compatible with Windows XP or Windows Vista are likely to affect Windows 7.
Even before the release of Windows 7, Microsoft has not promised that the OS is more secure against viruses. Improved security that Microsoft has highlighted the automatic data encryption for USB drives that control function for administrators who manage applications on a corporate network and malware filter in Internet Explorer 8 - was nothing of Promising prevent malicious software from working at all.

In fact, Microsoft has to be firm that Windows 7 users anti-virus software and regular updates of the system will continue to be safe.

"Security in Windows 7 is very complex and we have never recommended for customers to rely solely on a specific feature in the operating system," a Microsoft spokesperson said in a statement. "We recommend our customers to configure their computer to download and install updates automatically and install all security updates and service packs, if necessary, to ensure the highest level of protection against malware and other threats security. "

Many security researchers agree that the Windows operating systems are more vulnerable to malware. This is because the vast majority of PC owners are Windows users, and are "wicked" greater economic incentive to attack Windows systems.

So, even though Windows 7 comes with several built-in security that Apple's Mac OS X, the Mac is more secure because fewer attackers targeting platform less popular.

"If you're a villain and save you money ... you do not want 90 percent of your time on Windows and Mac spend 10 percent," said Charlie Miller, a security expert and author of The Hacker Mac Manual, in an interview with September. "You're going to spend 100 percent of your time on Windows."

Sophos says that the "lesson" of the test malware, you still need an anti-virus on Windows 7. This hardly seems to be a new lesson, because Microsoft never told anyone to stop running anti-virus. In the first place,

So why Sophos is "disappointed" with Windows 7? Obviously, the company is sensational their results in order to sell more anti-virus software. All this was already obvious, if numbers help confirm previous assumptions.

Everything you need to win the Sophos report is confirmation of something you already know: While you are using Windows, you need antivirus software. So make it work.

Reasons to Avoid Windows 7

Windows 7, hits stores becoming the best version of the Microsoft operating system is still widely used.

But nothing is perfect. Windows 7, like everyone else, has flaws - some of them major. on Tuesday a list of good reasons to change to Windows 7, including an improved user interface, improved compatibility with newer hardware and a seamless entertainment experience. (For more information, see our first look at Windows 7)

The reasons why you consider skipping this upgrade ever could: Now look at the other side of the story.

Upgrading from Windows XP requires a clean installation
If you are a Windows XP user, upgrading is not as simple as inserting a disc and start the installation. Instead, you should back up your applications and files, erase your hard drive and perform a clean installation of Windows 7 After Windows 7 is installed and running, you must manually install the software and re-use your library files or file transfer trust Microsoft to migrate your files for you.

We see this not so much of a headache as the data backup must be performed regardless of whether you are moving to a new operating system. In addition, a new facility is to be preferred in order to ensure proper performance. But we understand why this would bug many XP users. On the one hand, it's time. On the other hand many are sensitive to their data, and they do not have to trust Microsoft. (We do not blame them.) Third, if XP works well for you, why fix what is not broken?

Vista users, on the other hand, can upgrade to Windows 7 without reinstalling. You might as well get out of this train wreck, because it's easy.

The upgrade is expensive
Windows 7 is not cheap. Prices vary depending on the version you choose, but you'll pay at least $ 120 to upgrade from XP or Vista. And if you do not already have a copy of the Windows operating system, you have to pay the full price of at least $ 200 for Windows 7.

In the software market is not ridiculous $ 120 for an upgrade. Apple Mac OS X Leopard costs $ 130, for example. However, Apple plans its next operating system, Mac OS X Snow Leopard for $ 30 to sell current Leopard users. This change in power, because Apple Windows 7 Download look pretty steep.

It costs you time,
Customers are most likely to decide against the upgrade to Windows 7 because the company money. Joe Ansel, owner of a company that is considering the development of science centers, wrote in an e-mail to outlines the reasons for not upgrading to Windows 7: "The improvements will cost us time and money we play with our computers to do them things they used to do seamlessly -. while the phone never rings, and you get 60 emails a day Do not get me wrong, as a business owner, the cost for the update itself is nothing compared to the loss of wages to try to do the new operating system, what did the old. "

Ansel added that companies feel to perform the arcane software also reluctant to change. Microsoft promises Windows 7 will support almost every piece of software is compatible with Windows XP, and in rare cases it is not, it is an XP virtualization mode backward compatibility. However, companies invest thousands of dollars to create a stable environment, and it's easy to understand why they do not want their non-apple cart upset.

It is still under Windows
Despite the provision of a modern and intuitive interface in Windows 7, the OS is still Windows. In our first look at Windows 7, we complained about the inability of the operating system detects an Adobe AIR followed by his inability to a program to run the file.

In addition, Windows 7 is not immediately know what to do with certain tasks rather obvious. When you insert a USB drive, for example, you must have Windows 7, (ie open the folder to view files) to do what they tell and adjust the settings to get the OS to behave in this way. In short, if you start you need to do a lot of tweaking and adjustment to ensure a smooth transition. Unfortunately, it is an experience that all Windows users are accustomed to - things "just work".

Security is not always better
Steven Vaughan-Nichols Computerworld is confident that Windows 7 will not change anything in terms of security: "Windows 7 still has all the security of a drunken teenager in a sports car," he wrote. "Millions of Windows users are lazy, why the Internet is a mess. If you already do all the right things to keep XP running safely, you're not going to buy Windows 7 safe"

Good point. Since Windows 7 Windows yet, you are again the main target of attack by hackers and virus writers. Therefore, it is up to you to protect yourself with anti-virus software update and patch management to keep the operating system as safe as possible. (Compare this experience to Mac OS X Leopard, many of them have not even run anti-virus software because it is more secure out-of-the-box compared to Windows.) Although Windows 7 makes the desired functions security such as data encryption for USB, and control a function for Administrators, which applications running in a corporate network, this is not a general security improvements that change a lot to. the overall experience of the user

Integrated Management of Hardware-Based DRM obvious
Paranoid XP users will not want to move to Windows 7 for the same reason they do not have to Vista upgrade as Vista, Windows 7 supports the digital rights management technology, the rules, how would your media. Although some naysayers have called Microsoft DRM "draconian" DRM implementation has not materialized to withstand significant impact yet.

Ars Technica has a detailed explanation of the DRM issue. In short, the technology called protected Video Path (PVP) and Protected User Mode Audio (PUMA) provide secure playback of video and audio or .. "Little or no media effectively requires the use of protected channels, so most systems other than Windows users," wrote Ars Technica Peter Bright. "Playing unprotected media on a Vista machine, and in DRM systems just do not get used."

However, it is people who are in fear that one day PUMA and PVP can be bolted to the. Or an operating system completely open, like Linux - and for this reason they will stick with XP.

Snow Leopard is almost here
Apple new generation Snow Leopard comes September - a month before Windows 7 Apple's OS promises to offer many highlights improvements in Microsoft Windows 7 - 64-bit addressing, improved efficiency of management tasks on multiple processors, and others. It is unknown which operating system is better, but from my own perspective as a long-time user of Mac, I will say that I'd rather have the current Mac OS X Leopard to Windows 7 If you move to (or willing) to a completely different operating system, OS X Snow Leopard is an option before they consider themselves to Windows 7 Search.

Do the disadvantages outweigh the advantages? That probably depends on how much you are already in Windows. If you are using Windows Vista, the upgrade to Windows 7 is a breeze. Most of those who should currently Windows XP also enjoy the friendliness of Windows 7, increased device support and other functions. But if you have a Linux or Mac OS X, Windows 7 does not offer much to do you.
