On today’s internet, you can never be too careful about what you view or download. A good antivirus is essential for anyone using the internet for more than the most basic of tasks, but there are many options available, and they are not equal in the quality or degree of protection they provide.
Two of the most popular Antivirus software’s are Norton’s antivirus and Mcaffee, unfortunately, due to their popularity and the fact that they are pre-installed as trial versions on so many computers, these are often the first two Antivirus software’s that virus writers work to disable and this greatly reduces their effectiveness. While there are quite a few advanced security suites that are fee based, the comprehensive solutions too often bombard the user with constant pop-ups asking what to do, and for most people these become such an annoyance that they either just click on them to get them out of the way, or disable them, which defeats the purpose of having those features in the first place. Generally for most users, a free version of one of the current Antivirus software’s will provide adequate protection with minimal annoyance.
A good choice, and one that comes without costly subscriptions, is Avast Free Antivirus [http://www.avast.com/en-us/index]. Avast is a very old brand, originating in 1988 as a tiny program designed by two Czechoslovakian university students to remove the then-common Vienna virus. Today, it is a major competitor in the antivirus market, with over 150 million users. The latest iteration of the software has three versions (Free, Pro, and Internet Security) [http://www.avast.com/en-us/free-antivirus-download]. The Pro and Internet Security versions come with some additional features, such as spam blocking and an integrated firewall, but for the majority of users, the free version provides enough security.
The most basic component of Avast (and any antivirus) is the ability to scan your computer for malware and then to remove any that is found. In this field, Avast can hold its own with other similar products. What makes Avast great, however, is the inclusion of so many extra features. First, there’s an entire suite of real-time scanners, checking websites, network connections, emails, and even scripts running in the background. If any signs of malware or suspicious behaviors are found, Avast will alert you and provide options to terminate the connection or process before damage can be done. Also included is “sandbox mode”, which isolates programs from accessing any important system files until you approve them as safe. Avast also makes use of cloud streaming technology. It uses this technology both to stream updates to your computer and to keep a database of programs. When a program is run, Avast checks against the cloud database to see what the reputation of the program is. If the program has been marked as dangerous or is unknown to Avast, it will warn you and offer to run the program in sandbox mode until you decide whether to risk it.
