The Kaspersky free Antivirus is a computer security software. This software was designed by Kaspersky Lab, a cybersecurity and anti-virus provider headquartered in Moscow, Russia. Kaspersky Lab was founded by three individuals namely Eugene Kaspersky, Natalya Kaspersky, and Alexey De-Monderik in 1997.

Very recently, this company received recognition as a 2018 Gartner Peers Insights Customers’ Choice for Endpoint Protection Platforms. With 400 million users, Kaspersky Lab Technologies is a force to reckon with in the tech security space. The first release of the Kaspersky Antivirus software with its Freemium license was in 1997. The Kaspersky Free Antivirus 2019 release is already available for downloads. This software is compatible with various Windows-based desktops & laptops.

Kaspersky free Antivirus is used to tackle viruses from attacking PCs, block Trojans and various form of malware, and also warn about suspicious websites. This software provides necessary protection for PC.

Kaspersky Antivirus is free to use, and although it has limited features when compared to other Kaspersky security products, it successfully imitates the security feature of premium products. According to 2018 statistics, Kaspersky Lab has a 6.25% share of the tech security market.

Protection capabilities

In 2018, Kaspersky Labs was accused of spying on data on behalf of the Russian Government by the U.S. political class which led to the ban by President Trump across all federal agencies. However, we don’t find any compelling evidence to conclude that Kaspersky products are compromised and thus recommend it for protection of data and computer.

The Kaspersky Lab Antivirus (either 19.0 or lower versions) protection comes in three layers. First, the file scanner feature in the software scans the PC for local threats and recognized virus and malware. After that, heuristic analysis, an improved design on signature detection compares the scanned information examining the code for suspicious properties synonymous with known malware attacks. Lastly, Kaspersky’s online security network examines the issues and thereafter updates the user’s database for improved security measures.

Unlike many free Antivirus software, Kaspersky free Antivirus can be used to schedule a scan. It also offers to scan all inserted USB drives. A quick scan action can be performed using the software, likewise a full-system scan, custom scan, and removable drive scan.

As part of its measures of improving security, Kaspersky Antivirus collects data from the computer about location, malware threats details, etc. However, you can opt out of this feature.

German Lab, AV-Test reports that this software recorded a 100% protection against 0-day malware attacks when tested. Also, it records a 100% detection of malware discovered in the last four weeks. You can download the Kaspersky Antivirus here.
