Installation Process

Kaspersky Free Antivirus Download

The installation of the Kaspersky Free Antivirus is extremely simple and takes a few minutes. The process requires minimal user intervention. Our Score: 10/10.

On the official website of the Kaspersky Free Antivirus, click on the 'Download Now' button to begin the download of the installer file. We found that the installer exe is pretty small and takes a few seconds max to finish the download.

Once the download is complete, we recommend running the installer file as an administrator to grant all necessary privileges necessary for successful software installation. The software installer would connect you to the Kaspersky Lab Server.

The software would then require you to confirm your participation in the Kaspersky Security Network (KSN), which provides cloud-based protection to your PC. We recommended checking this option for maximum protection. Make sure you've read the KSN Statement before you agree to try this feature. Click on 'Install' option to proceed further.

Overall, the installation process is fairly simple and easy for first-time users of this software. It is recommended to uninstall all previous antivirus and malware protection software before you proceed with the installation. We also recommend restarting the system after installation to ensure all settings take full effect before you use the software.

Ease of Use

Kaspersky Free Antivirus Dashboard

The Kaspersky Free Antivirus User Interface (UI) is easy to use and navigate around but could have been more enriched with all features packed in given a front seat in the UI design. Our Rating: 8/10.

We liked the Kaspersky Free Antivirus interface, however, felt that it could have been improved, especially considering the powerful features the device packs in. The software UI designers choose to bury many of those deep inside the settings menu when they could have actually showcased them on the Dashboard itself. Instead, the Dashboard currently houses links to upgrade-only features. Click on the 'Details' button on the top to bring up the Notification Center.

Kaspersky Free Antivirus Details

This is where all crucial notifications, which frequently require user intervention, are placed. We recommend updating your virus database and definitions by clicking on the 'Run Update' button if they are out-of-date.

Antivirus Protection

Kaspersky Free Antivirus Task Manager

The Kaspersky Free Antivirus provides top-notch malware protection with multiple folds of security. We were really impressed with the span of the antivirus coverage- kudos to the developers! Our Score: 10/10.

Antivirus software provides two mechanisms for security to the users: automated protection, which ensures that the files on the system are secure in real-time, with the antivirus software taking a proactive approach in keeping them safe with minimal user intervention, and, manual protection, which entails scans manually scheduled by users themselves. Let's take a look at the two components inside Kaspersky Free Antivirus in detail.

Automated Protection

The Kaspersky Free Antivirus software provides some of the most powerful automated protection measures unlike others we've ever seen before in its peers, but, strangely enough, abstracts them from the user, hiding them deep under the settings section.

Kaspersky Free Antivirus Settings

Click on the small cogwheel icon on the bottom left of the UI to bring up the Settings screen.

Protection Shield

In the 'General' section of the Settings screen, you'll see the 'Protection' setting. We recommend leaving this turned 'ON' always to ensure your antivirus starts running from the moment the system is booted and keeps protecting it until the end of the session. We were really amazed by the level of customization each option provides- you can see individual options to customize just about everything in the software.

Kaspersky Free Antivirus Manage Settings

Click on the 'Default Settings' option for example, to choose the desired security level. There are 3 options to choose from: Maximum, Optimal, and Minimum. We recommend leaving this setting at 'Optimal security level' unless you suspect you live in a heavily infected environment.

File Anti-Virus Shield

Kaspersky Free Antivirus Protection

Navigate to the 'Protection' section of the Settings screen and you'll be able to see the File-Antivirus shield, which scans all files that are ever opened, run on the system, or saved. Click on the 'File Anti-Virus' option to customize its controls further.

Kaspersky File Antivirus

You'll be able to set the security level from High, Recommended, and Low, and also set the action the software would take upon threat detection. You could either leave this setting to 'Select action automatically' if you'd like the system to automatically make the best choice for you, or, for full manual control, choose 'Block', 'Disinfect', 'Disinfect, if not possible- delete', or 'Delete'. The level of customization is one of the deepest we've ever seen, something which seasoned antivirus users will enjoy and greatly appreciate.

Web Anti-Virus Shield

This shield ensures your PC stays safe online. It will scan, in real-time, the incoming web traffic and prevent malicious scripts from running. We recommend leaving this control turned 'ON'. Once again, you could click this control to fine tune it.

IM Antiv-Virus Shield

This shield will scan all incoming and outgoing messages on your IM apps to detect and control malware. We recommend that you leave this control 'ON'. 

Mail Anti-Virus Shield

The Mail antivirus shield scans the messages, both incoming and outgoing for potential threats and malware, for, this is one of the most common ways viruses are spread from system to system. We recommend leaving this control set to 'ON'.

Performance Impact Control

The Kaspersky Free Antivirus allows you to control the impact of the automated protection on system performance and resources. You can disable scheduled tasks when running on your battery or disable notifications. There's even an option, which we highly recommend keeping activated, to search for traces of malware in software, which are deliberately concealed- the notorious rootkits. Once again, the software shines in the very deep levels of customization that it offers, which many of its peers so utterly lack.

The user can click on the 'Pause File Anti-Virus' option to set a time when this automated shield would be disabled. It can also be deactivated when certain pre-listed apps are started!

Scan Controls

Click on the 'Scan' option in Settings to bring up this control. Users are able to choose here the security level desired, the action to be performed on threat detection, as well as set advanced settings for further calibration.

Additional Automated Protection Features & Controls

Clicking on the 'Additional' option activates the settings screen for additional automated protection settings.

Update Controls

The setting determines when updates are installed. We recommend leaving it set at the default value. You can also control the update sources, which are set to Kaspersky secure servers.

Threat and Exclusions

The 'Threats and Exclusions Settings' screen allows you to specify the type of malware you wish to be protected against. You can choose to be protected against other, rarer malware forms too, including remote controls software. Exclusions and trusted apps can also be defined in this section.


This feature allows the system to main self-defense mechanisms. This will block attempts made by malware to change or delete crucial Kaspersky Free Antivirus files and processes, so it can continue to protect your PC at all times. We highly recommend keeping this setting enabled, always.

Network Protection

The Network shield will monitor web traffic as you interact with web pages to discover malware. You'll be able to fine-tune controls here, and even access advanced settings if you are comfortable changing system behavior in accordance with your needs. Exclusions can be managed here as well.


These control the notifications displayed to the user. We recommend leaving the notifications activated to stay up-to-date with security updates and alerts.

Reports and Quarantine Behavior

This setting controls the behavior of generated reports and quarantined objects. If you wish to control how long infected files remain inside the quarantine, this is where you'll be able to do so. You can also manage the size of the Quarantine vault itself.

Additional Protection Tools

Within this section is located the 'Kaspersky Security Network', which uses a cloud-based knowledge base to scan applications and websites. This is a great way to detect new malware threats and also reduces the instances of false alarms and detections. We recommend leaving this feature activated for the best protection.

Manual Protection

Kaspersky Free Antivirus Scan

Clicking on the 'Scan' button on the Dashboard brings us to the manual scan section, where users can schedule and run scans on their PC and the files contained therein. There are various options when it comes to scanning types.

Full Scan

This is a comprehensive scan of the entire computer. We highly recommend users to run the 'Full Scan' once every few days to ensure their system is free of malware. This is particularly important for those who download music and movie files extensively on their computers. This scan is also recommended the first time you run the Kaspersky Free Antivirus software.

Quick Scan

The 'Quick Scan' will scan all objects loaded into the system memory since the machine was started. It takes only a few minutes to complete and can be used when you are short on time.

Selective Scan

External Device Scan
