MOST EFFECTIVE FREE ANTIVIRUS

MOST EFFECTIVE FREE ANTIVIRUS

Today we will try to answer at these questions to looking for the most effective 2011 free antivirus :

1. What is the most powerful antivirus ?
2. Which antivirus lighter ?
3. Which is the most effective antivirus ?

Let us first to see if there is actually a virus better than another.

The majority of antivirus present in circulation today uses heuristic algorithms, ie algorithms that, in an almost intuitive, trying to discover if, in a certain file or process, may hide some malicious activity. To understand how works an algorithm, we think at keylogger, spy little program that, once installed on a computer, without your knowledge, store in a text file, everything you write on keyboard. If, for example, you enter username and password for online banking accounts, will be found, in the text file, these data. Once hacker enter into possession of this data is trouble for the user. Well, new antivirus, more advanced, recognize this type of process and warn us of their presence.

What is the most powerful antivirus ?

So, to answer the first question, antivirus more powerful is than that, not only recognizes viruses, malware, backdoors, etc..., already popular, but antivirus discover new threats by analyzing the processes (heuristic algorithms).

Which antivirus lighter ?

In reality this is a not correct question, because when we talk about light antivirus is obvious that we refer to the amount of RAM that uses and CPU resources. It's clear that, to have a recent version of NORTON or ESET NOD32, installed on a Pentium IV, leads us to say that none of these 2 virus is light. Antivirus application, usually at startup, active scanning process in background, a updates control process for the database and the program and perhaps some other process that depends on each individual antivirus. For example, there are some who scan in real time the links on a webpage that we open.

All good and effective antivirus exploit the memory needed for their activities. More powerful processor and more RAM we have, less we feel its weight. On a Core 2 Duo computer, I3, I5, I7 4-6 Gig of RAM will never feel the heaviness of a antivirus. Obviously when we make a full scan, memory usage increases. But then, we can have 4-6 G. of RAM but have dozens of processes in place and then the problem is not in the lightness or heaviness of antivirus.

Which is the most effective antivirus ?
What there is not even caught a virus, what it feels risky opening a web page or an executable program. But really there is the virus most effectively ? I think its not just for the heuristic system in real time above described. In fact, hundreds and hundreds of viruses are created and placed on the network every day and only an alert to these centers of any anti-virus software companies can afford to create an "antidote" to enlarge the database and computer viruses that then we update. Here the importance of doing the update of the database every day.

But since you have come here hoping to find an answer to your research and that is an effective antivirus light and, of course, free for home use, I will tell you a post where I describe effectively the most popular antivirus 4, effective, lightweight and freeware for 2011 :

THE BEST FREE EFFECTIVE AND LIGHT ANTIVIRUS SOFTWARE

THE MOST POWERFUL ANTIVIRUS IN THE WORLD IN 2010

THE MOST POWERFUL ANTIVIRUS IN THE WORLD IN 2010

Choose an antivirus for your computer today is really a business. The choice is possible between different security software, but sometimes we do not know the rule, because we do not know enough about the "threats" from which we must protect our workstation PC.

Before choosing an antivirus suit our needs, we need to know for what kind of use we will use it. Everyone thinks that each antivirus can defend ourselves from any "evil" file trying to enter and infect your PC. Not so. There are antivirus that will allow us to more effectively defend against spyware, trojans and backdoors, others by the phenomenon of phishing.

When we decide for an antivirus, it should have the following features and capabilities :

1. Minimum system resources and CPU used.
2. Constantly updated virus database and program.
3. Clear setting clear and simple parameters.
4. Heuristic scanning system in real time.
5. Scan links present on Web sites we visit.
6. Anti-phishing feature.
7. Function of spyware protection.
8. Fast and efficient scan of your system.
9. Control of compressed files on your hard drive.
10. Checking the mail clients and especially attachments.

When you visit a site of a antivirus will notice that there is always a page where they are listed in detail the basic features of the software. These features are read as it is here that we find differences, relevant to our choice. As indicated by the title of the article, I will show you the most powerful antivirus 2010 in the world. It may seem crazy to mention the more powerful given that there are many very effective, but reading and reviewing the technical characteristics of dozens of anti-virus programs, I concluded that NOD32 is really exceptional.

Mind you, I'm in favor of free software and open source software but when it comes to protecting your PC, especially if containing important data, I believe a small fee needs to be addressed in this case. In many posts I talked about Avira, Comodo, AVG, Avast and I think the freeware versions are very effective but NOD32 (which is not free but a shareware trial version) is a foot higher.

I invite you to read my previous article where I talked about these and also ESET NOD32 antivirus :

THE BEST FREE SOFTWARE ANTIVIRUS

THE BEST FREE ANTI-VIRUS SOFTWARE TO PROTECT THE PC

THE BEST FREE ANTI-VIRUS SOFTWARE TO PROTECT THE PC

The title of this post is not correct, as I realized that the best antivirus there is not. The algorithms used are very advanced up to the use of heuristic algorithms to scan very well made. By now, all major software companies that create and update antivirus programs are progressed and the choice depends a lot from us. Certainly there are more bad software to be excluded. So there are a number of other best software around for virus protection. We are in 2011 and I will list those who are undoubtedly the most used and most efficient freeware virus protection.

Before listing, I explain what's a computer virus. A virus is a small program created especially by so-called hackers, with various features. A virus can take a specific name according to that for which it was created :

SPYWARE : these viruses are designed to be installed on PCs and "copying", storing them properly, sensitive data in your hard drive. It 's so that those have current account data on your computer, can be seen the account emptied.

BACKDOOR : a type of virus that sets himself the task of putting in touch our computer with hacker  computer. The attacker then gets full control of the infected PC and can do whatever he wants. The connection, of course, is so invisible and we do not notice anything.

But the list is endless as there are all types of malware as various troyan, rootkits, etc. ... It's good to say that rootkits are programs designed to hide certain processes on your PC. There is therefore said that they can hide but may contain viruses in some cases. In fact because of their characteristic hide processes, some malware exploiting them.

As mentioned, the list of viruses is endless. Where can they hide these viruses ?

1. Through pictures and images that are downloaded or attached to email.
2. In executable programs (.exe).
3. In various links on the web.

But we now see the list, describing the main features which the best free software for effective protection against viruses. Among the four that I will list, there is one that has not a freeware version (ESET NOD 32) but you believe me, it is exceptional.
