FAQ

    Why Should You Believe A Word We Say?

    One of the most crucial aspects of selecting the right antivirus is - who should you trust? With fake review sites and fly-by scams everywhere, it is a challenge to find a trustworthy source. Choosing the appropriate security for your digital life is easy with our guide. The sad fact is that most of the teams that recommend antivirus products have never tested or even installed the products themselves. Why should you base your decision on a Top 10 antivirus list generated by a Top 10 marketing group?

    Our goal has always been to maintain our reputation for being the most trustworthy and reliable buying guide for antivirus software. From the very beginning, we took a different approach. Rather than putting together a quick Top 10 list that only included antivirus software with high affiliate payouts, we identified the most reputable antivirus solution providers by researching the market. We opted to only add established brands with a great reputation and broad recognition in the industry. We purchased each antivirus premium package and then we did our research online. We established a benchmark for each antivirus package using our unique proprietary scoring system that we will discuss further below.

    Why should you listen to us? Our team consists of expert software testers and reviewers with over 30 years of combined experience. Trust, integrity and transparency are the basis of our unique approach to recommending antivirus products.

    What Are The Best Antiviruses?

    We examined respected antivirus testing labs for many hours, and we put together any malware and virus detection info we uncovered. Some of the most dependable and trustworthy sources included AV Test and AV Comparatives, however, we did even more research. PcMag, The Anti-Malware Testing Standard Organization, Ars Technica and Project Zero from Google are just some of the whitepapers and articles we also used. By doing this we were able to pinpoint the antivirus software technical requirements and the best way to score each antivirus package.

    Being able to detect threats is important, but it is not the only deciding factor. It is important to consider other key factors, including software specs, user-friendliness and system performance. In our office, we tested them on PC and Mac systems. Once the list of features has been determined and the scoring system was established t for each function, we installed the antivirus programs. Carrying out the tests has been time-consuming, however, we learned a lot about virus protection software by comparing it with others. In the weeks to come, our blog posts will include those features. Although we were almost finished with the scoring table, we still needed to consider one factor more: pricing.

    Should You Invest In The Best Antivirus Software?

    You will find lots of information and entertainment online, but there's also a lot of danger with every click. You may think the best antivirus measure is to stay away from downloading dangerous files; however, this is not the reality.

    Viruses can sneak into your system undetected and you may lose access to your computer or have your data stolen. The worst thing about this is that you won't realize how serious this is until it's too late. Therefore, it's crucial to have some kind of defense on your system. It is still possible to find the best antivirus for your budget even if you do not have too much to spend that will provide the proper protection.

    You can safeguard your computer and your personal info by installing an antivirus program. You can defend your computer from hacker attacks and ensure your information will not get corrupted and infected. It's the best way to relax when trying to work, watch a movie or play on your computer. 

    While there are free options available online, investing in an antivirus is definitely a good idea because of its numerous benefits. You can take advantage of an array of bonuses, which can make you feel much better while browsing the web or downloading files. Online shopping will be safer, secure your whole home network and shield children from unsuitable content.

    Some viruses cause your system to slow down and make some files unreadable. With other viruses, you'll be unable to tell if something's wrong, therefore, staying away from obvious threats shouldn’t be your only option. If you buy security software, you'll be protected from any threats, even if it is hard to detect them. Furthermore, if you experience any problems or get an infection, professional assistance is available from the support team of the antivirus creator. This will keep your computer free of viruses and malware.
