Why You Should Trust Us

When choosing the right antivirus to buy, one of the most critical aspects of the research is who you should trust. With so many fly-by scams and fake review websites, it is difficult to find a reliable source, an authentic guide to selecting the right protection for your digital life. The sad truth is that most teams behind antivirus recommendation websites have never actually installed or tested any of the products they recommend. Why should you choose an antivirus starting from a Top 10 software list compiled by a marketing team?

Keeping true to our original goal of being the most trusted and respectable buying guide for antivirus software, we wanted to do things differently from the beginning. Instead of compiling a quick Top 10 list featuring the best paying antivirus affiliate programs, we started by researching the market and identifying the most reputable antivirus solution providers. We decided to include only established brands with an excellent track record and industry-wide recognition. After buying the premium package from each brand, we started researching online and benchmarking each product in our office using a proprietary scoring system(more about this on our blog).

But who are we? We are a team of experts in software testing and reviewing with a combined experience of over 30 years. Our aim is to bring a new approach to antivirus software recommendation, based on integrity, trust and transparency.

Finding The Best Antivirus

We spent hours researching the most reputable antivirus testing labs, and we compiled all the virus and malware detection data we could find.  AV Comparatives  and  AV Test  have proven to be some of the most reliable sources, but our research did not stop there. We have also read white papers and articles published by groups and institutions like  The Anti-Malware Testing Standard Organization,  PcMag,  Google's Project Zero,  Ars Technica, to name just a few. We were then able to identify the important technical requirements of antivirus software and to how to attribute a detection score to each antivirus.

While the detection capability plays a significant role, sellecting the best antivirus is not just about that. There are other important factors to be considered, including software features, ease of use and system performance. We set out to test those in our office on various PC and Mac systems. After deciding on a general list of features to check and setting a scorring system for each function, we started installing each antivirus package. Testing has proven to be a highly time-consuming task, but we were able to get some interesting insights when comparing various virus protection software, some of those will be featured in our blog over the following weeks. Our scorring table was almost ready, but we needed to take one more factor into account: pricing.

The Right Price

A fully packed antivirus solution with premium features may come with a hefty price tag. To justify a higher sale price, some companies will include many exotic features, but are those worth the extra cost? Along with the highly essential detection capabilities, we agreed to take into account only the must-have features of each package, the usability, the system performance, and the total price when deciding what the best antivirus is. At this time we realised that some virus protection packages swimming in all kinds of exotic features are actually highly overpriced.

Most antivirus companies offer excellent discounts, but you won't be able to see that when visiting their sites directly. Prices may go as low as 50% off on certain ocasions, and this changes the dynamics of sellecting the best antivirus. Wouldn't you choose an antivirus that has the same must-have features as a competing brand, but it is 50% less expensive? By partnering with various affiliate programs, we were able to provide direct links to antivirus offers at discounted prices. We took those prices into account when compiling the best antivirus software list, to help you make an informed decision when choosing the right protection solution for your digital life.

Why Should You Buy The Best Antivirus Software?

Today's Internet is nowhere near as safe as you'd thought, which is why it is important to have an Internet security system in place. You can't rely solely on your ability to avoid infected files or dangerous websites, since all the latest threats are created specifically to look like legitimate applications and services.

Malware can make its way to your personal files without leaving any visible clues, so you may find yourself with a broken system, stolen data or even worse, only when it's too late to do anything about it. However, installing an Internet security program on your computer will negate these risks, so you may work on your computer, watch a movie or play a game, without any worries. The best part is that you don't have to spend a fortune, even if you are looking for the best Internet security on the market.

Installing such a program on your computer is the best way to protect your computer and your personal data. You can be sure that your files won't be infected, corrupted or encrypted by ransomware. Furthermore, you will also be able to protect your computer from direct hacker attacks. It's the best solution if you want some peace of mind when working on a computer.

While there are some free protection software out there, buying one of the top 5 Internet security software can bring many more benefits. You will get access to a wide range of special features, which enable you to do anything, from surfing the web to working with sensitive data, without worrying about virus infections, hackers or online scams. You will no longer need to worry when you make an online purchase, when children use your computer or be concerned that a device could make your network vulnerable.

The effects of virus infections are numerous, from unusable files to an inoperable system. While some of them are immediately noticeable, some of them can hide in your system for a long time and you won't realize it. This, however, is not a problem for the best Internet security programs, due to their highly rated detection capabilities, so you can be sure that nothing bad is hiding in your system. Furthermore, if you do encounter an infection or other problems, you can request help from a professional tech support team, who are ready to assist you with any issues.

Choosing the best Internet security software

There are various aspects to consider when looking for the best Internet security software. Besides a multi-layer defensive system, with highly effective zero-day malware detection capabilities, you can also benefit from a wide range of features, dedicated to data security, user privacy, parental control and much more. These are the features that set the best Internet security solutions apart from many low-ranking antiviruses.

How performance is affected by an antivirus is a serious concern for many users, but not if you're looking at the best Internet security solutions we have picked for you. Modern antivirus programs have little to no effect on a computer's performance, so you can use your computer normally, without noticing any slow-downs or encountering too many notifications. The best part is that you still get a large amount of useful security features, so there is no trade-off between performance and protection. You can prevent the worse the Internet can throw at you, without sacrificing a significant amount of processing power.

With a basic package, you can protect your computer from almost any online dangers, but you can do even more if you look towards a higher package. You can plug security gaps, prevent hackers from gaining access to your personal files or prevent unscrupulous individuals from spying on you with your own webcam, so the mid-range or top-of-the-ladder packages are definitely a good investment. You could pay a bit more for an advanced package, but you can be sure that online scammers or fraudulent websites won't steal your money, thanks to your Internet security program's early warning mechanisms.

The best Internet security solution is defined by what it has to offer an how it can address your particular needs. Basic packages are good choices if you are looking for a baseline protection system for your computer, but a higher package would make more sense, if you also need to protect sensitive documents or protect children from inappropriate online content.

Internet security developers keep up with the latest spyware, adware, worms, Trojans, rootkits or ransomware, by constantly improving their products. It doesn't matter if you have a low-end computer, used by family members or a powerful laptop, on which you keep important work-related documents, you will certainly find the best Internet security solution that suits your needs, among our carefully analyzed antivirus products.
