Know the Strength and Weakness of Antivirus Program

You install an antivirus program on your machine because you want to protect your machine from any unwanted accidents, such as data corruption, data loss, system malfunction, and personal data theft. So far, the so-called antivirus program is indeed the only reliable program to block malwares coming from virtually everywhere. With the rising trend of internet usage, virus threats are considered much more menacing than they used to be. 

This situation makes the installation of antimalware program on a computer machine an unavoidable necessity. However, it is worth mentioning that not all antimalware programs give advantageous effect. In fact, almost all of those programs still have some shortcomings that make them not entirely reliable. If you want to install one of popular antivirus programs, it is recommended that you scrutinize its strength and weakness before installing it. You can learn about two strong and weak features of popular antimalware programs in this article.

1. Many antimalware programs are strong enough to keep malwares away from your machine.
Most programs that are considered popular today indeed claim that they are strong in some way in preventing malwares from attacking your computer. Avira, for example, proves its strength in protecting your machine by optimizing its detection rate and email spam filtering capability. There are also some programs, such as Avast, that improve their protection capability by performing boot-time scanning, which averts virus attack before it is being executed by the operating system.

2. Many antimalware programs are cheap.
There is no doubt that you want to keep your machine protected, but you also want to make sure that you don’t have to spend a lot of money to afford such protection. Fortunately, many antimalware programs are available for free, although you have to pay in order to enjoy the most optimal protection provided by those programs. Some paid programs also allow you to enjoy trial version before you decide whether to buy them. If you are a Windows 8 user, you can rely on Windows Defender. This application is theoretically free because it is bundled with the operating system that you automatically get when you buy the OS. Although it is free, its strength is averting virus attack is comparable to that of most third-party paid antimalware applications.

There are also some shortcomings that some antivirus programs have not successfully overcome.

1. Antimalware programs may perform erroneous test.
Because all of those programs try to prove their strength in capturing viruses, they often catch files that are actually not harmful. This situation is usually referred to as false positive. Avira is considered a very strong antivirus; however, many users have reported that it shows false positives quite frequently. Reporting for false positive is easy because most, if not all, antivirus programs provide their users with tool to tell the program that it has caught the wrong file; however, it is not always easy to determine whether false positive has actually happened. If you are not sure about whether a file captured by your antivirus program is safe or not, you can go online to look for websites that give you comprehensive report about how that file is checked by different antivirus programs.

2. Some antimalware programs may cause system malfunction.
Some Windows 8 users have reported that Avast causes problem to the system when it is installed on Windows 8-operated machine. The machine cannot start up properly and the screen turns black after log-in. Although this problem can be overcome by modifying Avast’s protection policy, the complication of doing such modification makes it difficult for casual computer users to install this antivirus program on Windows 8 while trying to avoid such problem.
