Avast Antivirus Real Time Protection Review
Written by the same firm that offers AVG Anti-Virus Software, Avast is like turning up the volume on your iPod to the full 80 watts per channel in a four-channel system so that you can literally blast any nasty stuff back to where it belongs.
If this were a motorcycle or racing track, you would find that Avast would probably be the pole sitter (starting car) and would lead the race through out as it passes trojans, links, bots, link kits and rootkits as if they weren't even there.
In their way, you have a system that performs much better and is much cleaner. In fact, the level of clean is amazing. One of the key features of the Avast software, another piece of thinking or "heuristic" software from AVG is its level of anticipation. Every time you are installing a software, it pokes around within the software package itself to see if the software may be bugged and if it is, it offers you two options, one let it go through - if you already used the software and know what it is there's no reason why not - but if it is new software, you can safely let it kill the intruder and you can find another piece of software to use.
Limitations Of Antivirus SoftwareAn antivirus is considered as a prerequisite for computer defense, safety, and security. Generally, it does the basic protection tasks for us, such as virus scan and defense, quarantine, and identity protection, among many others. A significant number of antivirus software is available both online and in CD installers. Each type of antivirus software has features unique from each other, such as adware blocking, malware defense, Internet surfing protection, and registry cleanup. However, computer users should not depend entirely on the antivirus and its capabilities.
An online blog highlights a common misconception about security and antivirus software. The said blog focuses on the belief of computer users that they can already chill and relax once an antivirus is present on their computer. This shows that the said computer users are not aware of the limitations of an antivirus.
In order to detect viruses, an antivirus needs pattern files that contain the most recent and updated information about the different viruses that exist. However, the number of viruses seems to increase at greater intervals than the antivirus pattern files. This means that one limitation of an antivirus is the slowness when it comes to the update and detection of newly-conceptualized viruses.
Antivirus software have limitations when it comes to defense against rootkits. Rootkits are harmful computer elements that attack on the center of the operating system of the computer. Also, they are not able to detect what we call the zero-day exploits, which are defined as serious computer infections that spread so fast that it may be late for the computer to identify it as harmful.
