Little about Free Antivirus
If you are running a windows PC, antivirus software is a MUST these days. There are dozens of free or paid antivirus software’s on the market. Which one to choose can be a daunting task. Their functionality is pretty much the same, they are all scanning your computer files. This is done by comparing a so called "virus signatures" (small amount of code extracted from the already recognized viruses) with your files. If your file contains a virus it will match a signature and the antivirus will give a signal for the infections . The antivirus companies are working around the clock in order to keep their signature databases updated, so that they can immediately recognize and neutralize all new viruses. According to statistic of major antivirus companies like Symantec, Kaspersky and others, we have more than 100 000 new variation of viruses on a daily basis.
Free antivirus software’s sometimes can be much better solution than paid ones. I mean you do not need to spend any money and usually you do not have any problems. It only takes a bit of understanding how things work on the net. The main difference, and I would say the only difference, (although here and there you might find some difference in the functionally as well), is that with the paid version you usually get a customer support service.
Microsoft Free Antivirus
Here is worth mentioning that by default Microsoft Window 8 and 7 are shipped together with the antivirus (if we can call it by that name) - Microsoft Security Essentials. He is considered as a baseline security and really, it cannot compete with all others specialized free antivirus software’s. Even Microsoft would not disagree with this fact.
OK, now, let's take a look at some of our top contenders.
Avira Free Antivirus - has been on the market for a long time and it offers all basic components. Real-time protection and system scanning are his basic components. There are additional features as well: firewall, mail protection, web protection but they are grayed out and only available in the paid version. Who needs them anyway, most of users get off really well with just the “basic features”. The overall good antivirus with long tradition and very easy to install, use and maintain.
AVG Free Antivirus - offers a powerful cleanup and protection features. He has been on the market for a long time. There are some reports on difficulties during installation process. If your system is already badly infected and crumbling, perhaps this is not the best solution. Once you are past the point of installation (once again: only if your system is really badly infected and damaged you should reconsider installing AVG) the AVG antivirus is running smooth and is doing pretty effective job at cleaning and protecting your system.
Comodo Internet Security Free Antivirus - is quite a newbie on the market, but it’s not to be underestimated. It offers some more advance features which are usually not shipped with free versions of other Antivirus programs. Those features are: specially security tailored browsers, which is a version on Chrome, DNS protection, firewall (quite useful feature) and a Behavior Blocker. These are protecting access to critical files and processes on your system. All of these are adding extra safety and taking care for the well-being of your complete system.
Malwarebytes Anti-Malware Free Antivirus - has a strong capacity for virus detection but it does not have a real-time protection like other Antivirus programs, hence it is a good practice to use him in combination with some other Antivirus. Malwarebytes could be used for daily or weekly comprehensive virus scans. The newest version 2.0 has a very friendly user interface and some cool feature and functionality improvements.
360 Internet Security 2013 Free Antivirus - has a very easy installation even on the highly affected systems. His behavioral based detecting system can sometimes produce false positive, which means that sometimes a legitimate (good) programs are detected as a virus and removed.
