AVG vs Avira vs Avast – Download Best Antivirus To Ensure Safety

September 11th, 2014

When you want to install the perfect antivirus software for your personal computer, it can be rather very hard for you to find the suitable program of software that you actually need. You surly desire a program that is able to fully protect your computer’s OS and your personal files.

Nonetheless, you definitely don’t want is to install one that has firm restrictions that it actually disables all the programs that you require to use on your PC. So, let’s learn more about three of the most favored antivirus programs available to help you decide which one is the best for your needs and to install it on your PC.

AVG antivirus

AVG is one of the leading antiviruses available that has been on the market for a couple of years. AVG is enabled to be downloaded for absolutely free, therefore this is a huge advantage for those who do not want to spend about $100 on a decent antivirus program. In addition, this software program has the capability to protect your PC from potentially websites that have viruses or malware and this program will obstruct your personal data from the hands of the hackers. Generally, this is a good antivirus software program that can surly protect your computer from a big number of viruses. Thus, there is a drawback, for instance when it have to protect against potentially menacing emails that are created and send especially in order of allowing the hackers to have the access to all of your personal files. Though, the company is in continuously working to fix this matter and upgrade the program, it still has some developments to be done.

Avira antivirus

Avira is the perfect software program for stopping viruses and malware, also blocking cookies and dangerous webpages. Nevertheless, the company does not provide any technical support, and also it has been reported that this system has entirely disabled the OS of the PCs on which it was set. Additionally, there have been some objections regarding the possibility that this antivirus is likely to make it virtually impractical to connect on Internet on some networks.

Avast antivirus

This program is the one that is a bit different from the other two antivirus programs regarding the way it works. Its user interface features an ample viewpoint on the health of your system or any potential risks of virus infections. Plus, it is in a constant scanning of your system and it is designed especially to obstruct fishing. Its biggest inconvenience is that it provides too much information to the user, which sometimes can be overwhelming. This makes it hard for the user to determine which information to consider and which to be left aside.


Overall, the best is one of the two contestants, either AVG or Avast. Usually, the AVG program does a excellent work on protecting your system from majority of threats, but if you think that you need a superior protection, the suitable choice for you is the Avast Antivirus, which is an magnificent program provided that the user has some knowledge about computers and to know how to set up the system and control it for becoming an effective antivirus rather than an annoying one. However, these software programs are an essential part for maintaining your PC protected and safe.


James Fields: Antivirus software still a necessary tool

May 16th, 2014

Have you heard? Antivirus is dead. Kaput. No longer relevant in today’s computer security world, where 315,000 new malicious files are detected every day.

When Brian Dye, senior vice president of information security for Symantec — the company that invented commercial antivirus software 25 years ago — told The Wall Street Journal a couple of weeks ago that antivirus “is dead,” loyal antivirus updaters across the world rightfully asked, “What does that mean?”

Let’s start by saying that while it makes a great headline, declaring that antivirus is dead is an exaggeration. Antivirus is still an important part of your computer security equation. However, believing that it’s the only part, and that antivirus alone will protect you, is highly inaccurate.

Antivirus is a piece of software designed to prevent, detect and remove malicious viruses from a computer system or network. Most antivirus software, traditionally and today, works by blacklisting malicious code. There are millions and millions of computer viruses out in the world — some of them existing and some original — and when antivirus software finds a known piece of bad code, it flags and bans it.

A blacklist protection system is always playing catch-up — it is always inherently one step behind. Though it’s flawed, antivirus software using a blacklist model is straightforward and easy to implement, which is why it’s been our most widespread computer virus protection system for the past 25 years.

A supremely superior model of security is white-label. Say there are 500 tasks that your computer needs to perform and programs it needs to run. If you already know that these 500 things are safe, a white-label system allows these 500 things and prevents everything else.

This method is incredibly effective and safe, yet very few people use it because it requires an enormous amount of effort to set up. Since you have to tell your computer each and every program it is allowed to run, this white-label antivirus model is not practical for most people at this time.

If blacklist antivirus is too little, and white-list systems are too much, to find the “just right” solution, I suggest taking a layered approach to your computer’s security. Your system needs to include a blacklist antivirus software program in addition to Internet filtering.

In this day and age, if you’re not filtering your Internet connection, you’re going to be attacked and hackers are going to compromise your systems. This goes for both personal and business use.

It’s important to note that, when implemented properly, Internet filtering can be aggravating at times, because by design it prevents you from going to some places on the Internet. This barrier can get in your way, preventing you from doing something that you want to do. The worst thing that you can do in this instance is shut off your Internet filtering. You can put all the safeguards in the world on your computer, but if you don’t actually use the tools, they’re worse than useless because they cost you money and don’t secure anything.

The last important thing to understand is that the general goal of computer viruses is to exploit some vulnerability in another piece of software on your computer, like Adobe Flash Player or Acrobat Reader. Even with antivirus software and Internet filtering implemented, you need to be sure to keep your computers and all the software that runs on them up-to-date all the time.

The next wave of antivirus software will cover all your devices — even at work

April 24th, 2014

McAfee and Symantec have had their day. Now a startup called Sentinel Labs wants a shot at the antivirus market.

Sentinel started last year, picked up some seed funding, and quietly released software to protect individual devices against advanced threats.

Then, customers told Sentinel what they wanted next was new antivirus software for all their devices, co-founder and chief executive Tomer Weingarten said in an interview with VentureBeat.

“We know the market is ripe for disruption, so we went with that vision back to our existing investors,” Weingarten said.

“We told them basically that we had already built the hardest parts here, which is an antivirus engine. Now we just need to build on that and built that entire offering for antivirus.”

The investors must have liked the pitch, because now Sentinel has completed a new $12 million funding round.

The funding hints at the value of bolstering security on the devices that lots of employees use — smartphones, tablets, desktops — rather than the networking devices that a few data center administrators might have access to. Funding for companies like Lookout Mobile and CrowdStrike, as well as FireEye’s Mandiant acquisition, also hint at the sensibility of keeping watch on individual client devices.

Even if Sentinel strives to keep all devices covered, it doesn’t want to slow down the performance of those devices. Its technology aims to use less than 1 percent of CPU and memory resources on a given device. Sentinel supports Mac OS X and Android, and it expects to announce support for iOS and Linux soon, Weingarten said.

But each operating system takes time because each one faces different attack vectors. Apple mobile devices could face man-in-the-middle attacks and malicious profile attacks, while Windows machines might deal with malware or Trojan horse attacks.

Sentinel can cover such threats, but Weingarten said, “For us that’s a very small portion of the entire picture.” Devices on many operating systems can remain protected even when they’re offline and unconnected to a network, he said. And the system is constantly tracking new patterns and making predictions based on threat intelligence it collects from devices it’s charged with protecting.

The company works with about 15 customers today in different stages of the sales process, Weingarten said.

Tiger Global led today’s round in Sentinel, which is based in Palo Alto, Calif. Accel Partners, Data Collective, Granite Hill Capital Partners, and the Westly Group also participated. To date Sentinel has raised $14.5 million.
