The Best Antivirus Software Buyer’s Guide
When looking for the best antivirus software to keep your computer safe, there are some vital things you need to consider. There are many antiviruses out there, and you need to look for the software that will not only keep your PC safe but also be easy to use, have a little performance impact, have great features, privacy, and more. Here are some of the vital things you need to look for when buying antivirus software:
The effectiveness of the antivirus software is one of the first and most important things you need to consider when buying antivirus software. This tool is meant to run virus scans for malware and viruses while also providing real-time protection. It also provides anti-phishing protection to block suspicious and shady sites that can steal your data.
You want to make sure the tool you choose provides such protection. It should also monitor unforeseen behavior and ransomware protection to ensure that your computer is always free of malware and viruses. The antivirus should have a very large database and be active enough to identify even the latest unknown malware and viruses.
➤ Low System Performance Impact
Another vital thing to consider is the performance impact of the software on your system. Viruses and malware do not only steal vital information, they also tend to make our system crawl and perform poorly. As such, the last thing you want is to install an antivirus that will eat most of your system resources and reduce its performance.
You should avoid antiviruses that tax the resources of a system. If after installing the software you notice some sluggishness in your PC, websites take more time to open, files take forever to copy, or your apps take a longer time to open, you should consider trying another program.
Fortunately, all the antivirus programs on our list are light on system resources. Most of them even come with a 30-day free trial to test the performance impact and functionality of the software before purchasing it.
In addition to having a low system performance impact, most of the options on our list come with utilities and tools that you can use to optimize your computer. This means the program will not only help to keep your system safe but also enhance its performance.
When looking for the best antivirus program, you need to consider your budget. Different programs come with different price tags, and you should choose a program that suits your budget. When it comes to antivirus pricing, you should know that the most expensive program is not the best and the cheapest is not the worst.
The price does not really determine how effective the software will be. Some programs also offer free packages that offer great security and protection but with limited features. Fortunately, most of these companies offer discounts, which you can take advantage of. You can look for discounts on the website of the company.
➤ Platforms and Number of Devices
You should also consider the platforms the antivirus software is compatible with. So far, Windows is the largest target for malware and viruses. The second operating system on the list is Android, but only less than one percent of apps installed via the Google Play Store are in the potentially harmful category. Mac and iOS have very low threats, thanks to the strict control of the app store of Apple.
Most antivirus programs are compatible with all these platforms. When purchasing the software, you want to make sure it is compatible with the platform you want to use it with. All antivirus software are compatible with Windows, but not all are compatible with other platforms. Again, some of them are only compatible with Mac, iOS, or Android on certain packages, so you need to subscribe to that package before you can use it on those platforms.
You should also consider the number of devices you want to connect with it. The pricing of those programs differs based on the number of devices you can connect. If you want to use it on just one device, then you would be fine with the single device package. However, if you want to connect more devices, then you should make sure the program has a plan that can cover all the devices you want to connect.
Paying for up to 10 devices in one package is much cheaper and cost-effective than paying for a single device package for all your devices. Hence, you want to make sure that the software and package you choose is suitable for all the devices you want to protect.
➤ Additional Features
Some antivirus software come with few options when it comes to feature while others offer loads of features. When looking for the right antivirus software, you need to consider the features you need. You should have a program that offers the features you need in addition to the basic protection features.
If you are more concerned about your online privacy and you do not want to invest in a VPN service, then you should look for an antivirus that has a VPN client. Some of the programs on our list come with this feature, but with limited use. For some tools, you would have to pay an additional fee to enjoy the full VPN package. This will help to save space and resources for running both an antivirus and a VPN tool.
If you want to control the way your kids use their devices and access the internet, you should look for a program that offers parental control features. This will help you to manage and control their devices. You can restrict the sites they can visit and monitor their online activities.
If you want your PC to be performing at its best always, you should opt for a program that comes with device optimization tools. These tools will help to enhance the performance of your computer. There are several other features that come with these programs. In all, you want to make sure the tool comes with all the basic features you need.
➤ Ease of Use
Another vital thing you should consider is the software’s ease of use. You want to make sure you choose a program that is easy to install, configure, and use. You can check if the antivirus is easy to use during the trial or free period phase. Install and use it for some time to see how you can cope with it.
