Antivirus software is designed to detect, remove and prevent computer viruses, Spyware, adware, worm and Trojan horses. This security program is highly vulnerable and easy to compromise when a PC is establishing connection to the internet. Antivirus software installation is not a choice, but it is essential to detect malicious activities of computer viruses.
How Antivirus software works
Learning how an antivirus program operates is quite tough. Every antivirus program works differently from each other. Antivirus software manufacturers employ a numbers of methods to remove Spyware, computer viruses and other nasty intruders. This software makes use of a database dictionary to scan various types of viruses. These database dictionaries contain comprehensive lists of computer codes and viruses matching each bug. Whenever a new application or program is installed, the antivirus software checks the dictionary for virus codes. If it finds any match, the antivirus software recommends deleting the program so that it may not damage your machine. It is the most effective and reliable way of protecting a computer from internet hackers and viruses. Since new risks and viruses are introduced every day, antivirus programs require periodic updates. Once a specific version of antivirus is purchased, security updates are free to download until a new version of this software is released.
There are many benefits of using a commercial antivirus program. One reason is that these products are embedded into a complete security suite with anti-Spyware, firewall, spam filtering and many more. All these protections provide a more secure coverage to your machine. If you cannot buy commercial software due to an affordability issue, you can use free programs that offer basic protection. However, you should be careful when choosing these free antivirus programs. Always download from a well-reviewed and well known source like Avast and AVG.
Now, the use of antivirus programs for mobile applications is also increasing due to the immense prevalence of wireless devices everywhere. It is very easy to trace unsecured wireless networks. Antivirus programs for mobile applications provide you remote protection and privacy control when your device is stolen or lost. This technology can help you find your lost phone. Though mobile viruses and worms are still uncommon, it is recommended to secure your mobile against device loss, data loss and other problems that can arise.
Consequently, an antivirus program is a necessary and sound investment for internet users. These days, there are a variety of antivirus software programs in the market based on personal and enterprise security requirements. This preventive medicine will save your machine, server or even network from bugs and viruses. It will save you from big losses and help you to run your system smoothly in the non-secure internet world. There are many reputable brands of antivirus software like MacAfee, AVG and many others. You should buy a home or professional edition from these trusted sources. You should read all features and specifications of the products before paying money for it. It is recommended to check their trial versions first to check the authenticity of features they are claiming for your network and computer protection.
