Kaspersky Internet Security 2021 is also our undisputed winner in 2021, and has superseded our other rivals such as Norton Antivirus 2021, Avast Pro Antivirus 2021, AVG Internet Security 2021, and Avira Antivirus Pro 2021. Although all these reviewed and tested antivirus software are highly recommended, Kaspersky’s lead in virus detection, speed, reliability and usability is unmatched. However, before we dive into reviewing the software, here is a quick note on expired software—if you have an expired license and are trying to acquire a new Kaspersky license, read this first:
Kaspersky Internet Security Download — Be Careful When Buying
Many users who have ordered the Kaspersky software through Amazon reported invalid or expired activation codes. Therefore, we recommend downloading the software directly from the manufacturer’s website:
It seems like the online stores such Amazon have old expired codes in stock—this may be due to the fact that the software stays in storage for too long before it gets sold. Some users reported that they purchased licenses that were already activated and/or expired weeks ago. Below is the direct link to the Kaspersky website:
Kaspersky Free Antivirus — Beware of Free Versions
Most negative reviews about Kaspersky found on the web are related to the license costs. It’s true that Kaspersky is not the cheapest alternative and it’s not free either. However, we already pointed out in our article, “The myth of free virus protection“, that the time of free antivirus programs are long over and all antivirus manufacturers nowadays put more effort into developing high-quality antivirus software in the licensed versions. The remaining free antivirus manufacturers usually consist of unreliable virus detection methods. And even worst, most of these free antivirus programs offer their software under the pretense of being an antivirus tool, but in fact provide a virus contaminated software known as adware (advertising software). Talking about free antivirus tools, Windows 10 created a built-in free virus protection program called AV-TEST, but it couldn’t protect the computer from viruses efficiently. Therefore, we can only advise you to buy from reputable antivirus manufacturers and abstain from free antivirus programs.
Kaspersky Internet Security Virus Coverage
Kaspersky Internet Security had to undergo immense antivirus testing from AV-TEST. According to AV-TEST’s new ratings, Kaspersky antivirus software placed itself as the number 1 antivirus program in terms of virus coverage. AV-TEST has attacked Kaspersky’s software with unknown and malicious viruses to test its effects.
The Germany-based company AV-TEST is one of the most well-known security software auditors independently checking all antivirus programs on the market for their virus coverage and promised security. The company has the largest collection of viruses in the world and has established self-developed testing methods that can detect the weaknesses of any anti-virus programs within minutes. It is also known that AV-TEST uses self-developed and insidious viruses to check whether antivirus manufacturers can even handle viruses unknown in the market.
AV-TEST’s testing methods have been a thorn on the side of antivirus companies for a long time. Just a few years ago Kaspersky’s CEO criticized AV-TEST’s processes—at a time when Kaspersky was still struggling with significant issues in the market, and had to submit to giants like Norton and Avira. However, times have changed. Years later in 2021, after immense development and research, Kaspersky successfully met the extremely demanding requirements of the AV-TEST. In the current AV-TEST report, Kaspersky was rated particularly well. Thus, Kaspersky 2021 may be the virus killer with the strongest virus coverage in the market as of 2021.
Kaspersky Internet Security Conclusion
In the 80s and 90s, Kaspersky was one of the antivirus manufacturers ahead of its time and had made a name for itself, even in the hacker scene using innovative methods.
Between 2011 and 2020, the company was struggling with major organizational and technical challenges. The reviews were mostly mediocre and for a while it looked like Kaspersky would not survive the competitive antivirus market. However, instead of selling the company, Kaspersky put all their eggs in one basket and redeveloped their software into one of the strongest virus killers in the world. The old hacker culture and 30 years of antivirus knowledge flowed into the new product line called Kaspersky Internet Security for the first time in years.
The new product, Kaspersky Internet Security 2021, has managed to establish itself as the undisputed market leader with hard work and years of investment. On a positive note, the company has not deviated from its course and has focused on a single product. The result is Kaspersky Internet Security 2021, which is currently superior in every way. Let’s hope it stays that way next year in 2022.
