Antivirus vendors have undergone significant transformations in their product offerings throughout 2026. ESET, for instance, has rebranded its home security lineup, introducing ESET HOME Security Essential and Premium, while integrating automatic ransomware backup into its Ultimate plan. This shift was marked by the release of version 19.2 of its core NOD32 engine on August 27, 2026. Meanwhile, IPVanish made waves on October 7, 2026, with the launch of a next-generation antivirus product built on the VIPRE engine, seamlessly integrated into its existing VPN application. For consumers who installed antivirus software two or three years ago, it is likely that the product name on the box no longer reflects the current offerings from these vendors.

The disconnect between what users believe they have and what is actually available is prompting many Australians to reconsider their antivirus solutions this quarter, rather than opting for automatic renewals. However, the process of switching antivirus software is fraught with risks. Running two real-time engines simultaneously can severely impact system performance, leading to crashes or slowdowns. Moreover, improper uninstallation of the old software can leave behind kernel drivers that obstruct the installation of new software. Additionally, forgetting to export license keys can result in the loss of a paid subscription. This guide outlines a comprehensive 13-step process to facilitate a safe transition between antivirus solutions, ensuring that users maintain uninterrupted protection.

Why Australians Are Switching Antivirus Software in Late 2026

Despite the growing number of Australians contemplating a switch in antivirus software, such changes remain relatively uncommon. According to Security.org’s 2025 consumer antivirus report, a staggering 84 percent of users made no alterations to their software in the preceding year. Typically, consumers only reassess their antivirus options when faced with specific triggers, such as price increases, new hardware purchases, or product discontinuations. In fact, earlier data from 2024 indicated that 46 percent of surveyed U.S. adults relied on third-party antivirus solutions rather than solely on built-in operating system protections, with 12 percent of those still using built-in security expressing intentions to switch within six months.

Financial considerations also play a role in the decision-making process. Security.org found that 54 percent of third-party antivirus users opted for paid versions, while 43 percent utilized free tiers. Similarly, AV-Comparatives’ Security Survey 2023 revealed that approximately 59 percent of respondents were paying for their security solutions. Interestingly, 83 percent of users reported satisfaction with their current products, which contributes to the inertia surrounding antivirus software switching. However, as the product refreshes of 2026 are examined, the cost of remaining stagnant becomes increasingly apparent.

Significant changes have occurred this year, particularly with ESET’s rebranding of its home security lineup, which replaced older names like Internet Security and Smart Security Premium. The new ESET HOME Security Essential and Premium tiers now include features such as a Website Security Inspector for real-time scanning of web content and a Microphone Monitor for privacy auditing. Additionally, the NOD32 engine has been updated to version 19.2, with the previous version now receiving limited support.

IPVanish’s recent entry into the antivirus market with its October 2026 release is noteworthy. This product, powered by the VIPRE engine, received an Advanced+ rating from AV-Comparatives in March 2026. Unlike traditional antivirus solutions, IPVanish has integrated real-time anti-ransomware protection and machine-learning threat detection directly into its existing VPN application, eliminating the need for a separate antivirus dashboard. For users already paying for a VPN, this consolidation presents a compelling option worth considering before the next renewal invoice arrives.

ESET vs IPVanish vs Staying on Windows Defender: A Quick Comparison

Before making a decision to migrate, it is crucial to evaluate the three viable options side by side, rather than relying solely on each vendor’s marketing claims. The following table provides a comparative overview of ESET HOME Security Premium’s features against IPVanish’s new antivirus module and the built-in Windows Defender that comes with every Windows installation.

Feature	ESET HOME Security Premium (2026)	IPVanish Antivirus (Oct 2026)	Windows Defender (built-in)
Core engine	NOD32 engine, version 19.2	VIPRE engine (AV-Comparatives Advanced+, March 2026)	Microsoft Defender engine
Separate dashboard required	Yes — dedicated ESET HOME app	No — built into the existing IPVanish VPN app	No — built into Windows Security
Ransomware file backup/restore	No on Premium (Ultimate tier only)	Not listed as a standalone feature	Controlled Folder Access only, manual setup
Website/phishing content scanning	Website Security Inspector, real-time	Web protection blocks malicious sites, ads, trackers	SmartScreen, browser-dependent
Download and exploit protection	Yes, via real-time scanning	Yes — download monitoring plus exploit prevention	Yes, baseline only
VPN included	Unlimited VPN on HOME Security plans	Yes — this is a VPN app with antivirus added	No
Household member management	Yes — “Members” model, assign devices per person	Per-device licence, no household roles	No multi-device management
Cost	Paid subscription, tiered	Bundled with IPVanish VPN subscription	Free, included with Windows

The comparison reveals that there is no universally superior option; rather, the best choice depends on individual needs and preferences. For users satisfied with Windows Defender, the rationale for switching hinges on specific feature gaps rather than deficiencies in Defender itself, which has consistently received competitive ratings from independent labs. For those paying for a separate VPN, the IPVanish option warrants consideration purely for its potential to consolidate services. Conversely, if ransomware recovery is a priority, ESET’s Ultimate tier is the only one that offers backup-and-restore capabilities, necessitating careful tier selection to avoid assumptions about coverage.

Prerequisites and System Requirements Before You Start

Before initiating any changes to your antivirus software, ensure the following prerequisites are met to avoid complications during the migration process:

• Operating system: Windows 10 (version 22H2 or later) or Windows 11 (24H2/25H2) for Windows machines; macOS 14 Sonoma or later for Mac migrations covered by IPVanish’s new antivirus and most 2026-era suites.
• Administrator access: Ensure you have a local account with administrator rights on every device you are migrating, as standard user accounts cannot fully uninstall kernel-level security drivers.
• Current antivirus version number: Document the exact build of your existing antivirus software for reference.
• New antivirus version number: Confirm the version of the antivirus you plan to install.
• Stable internet connection: A reliable connection is necessary for downloading the new installer and running the removal tool.
• 15 to 45 minutes of uninterrupted time per device: Plan for reboots and avoid starting this process during critical tasks.
• A password manager or notes app: Use this to record license keys, activation emails, and exclusion lists before removing the old software.
• Backup of irreplaceable data: While the process is not destructive, having a backup is a prudent precaution.

As a preliminary check, confirm which antivirus engine is currently active on your Windows system by running the following PowerShell command:

Get-CimInstance -Namespace root/SecurityCenter2 -ClassName AntiVirusProduct |
    Select-Object displayName, productState, pathToSignedProductExe

This command will help identify if any remnants of old antivirus software are still active, which could complicate the migration process.

Phase 1: Audit and Prepare (Steps 1 to 3)

Step 1: Audit What Your Current Antivirus Is Actually Doing

Begin by accessing your current antivirus dashboard and documenting all the features you actively utilize, such as real-time scanning, firewall rules, VPN, parental controls, and scheduled scans. This step is crucial as different antivirus suites offer varying feature sets, and a product labeled as “antivirus” may also be managing your firewall, DNS filtering, and backup schedules. Understanding what you rely on will help ensure that your new solution meets all your needs.

Step 2: Choose the Right Replacement Engine

Select a replacement that addresses your specific needs rather than being swayed by marketing hype. If consolidating your VPN and antivirus into a single invoice is a priority, IPVanish’s October 2026 antivirus release may be ideal. Alternatively, if ransomware recovery is crucial for your household, ESET HOME Security Ultimate offers automatic backup-and-restore features. For small offices, ESET Small Business Security now includes the same ransomware backup functionality previously exclusive to home users.

Step 3: Export License Keys, Exclusions, and Settings

Most antivirus dashboards provide an account or license tab where you can find your key, renewal date, and number of activated devices. Take a screenshot or note these details. Additionally, remember to export any exclusion lists you’ve created, as these do not automatically transfer between vendors. Rebuilding these lists from memory after the migration can lead to unnecessary complications.

Phase 2: Remove the Old Antivirus Cleanly (Steps 4 to 6)

Step 4: Download the New Installer Before Touching the Old One

Before uninstalling your current antivirus, download the new installer and save it to an easily accessible location. This precaution ensures that you have the installer ready in case the old antivirus disrupts your download capabilities during the uninstallation process. Always verify the downloaded file’s integrity by comparing its hash against the vendor’s published hash.

Step 5: Disable Tamper Protection and Self-Defense Modules

Most antivirus products include self-defense modules designed to prevent unauthorized changes. This protection can hinder the uninstallation process, so it’s essential to disable it before proceeding. You may need to re-enter your product password or confirm via a two-factor prompt to complete this step.

Step 6: Run the Vendor’s Official Removal Tool

Do not rely solely on the standard uninstall process. Each major antivirus vendor provides a dedicated removal tool to eliminate leftover drivers and services that standard uninstallers may miss. After uninstalling the old software, reboot your system and run the vendor’s removal tool to ensure a clean slate for your new installation.

Phase 3: Install and Verify the New Engine (Steps 7 to 10)

Step 7: Reboot, Then Install the New Antivirus

After rebooting, proceed to install the new antivirus software. For ESET HOME Security, the installation process will guide you through selecting the appropriate tier, while IPVanish users will enable the antivirus feature within the existing VPN application.

Step 8: Verify Real-Time Protection Is Actually Active

After installation, it’s crucial to confirm that real-time protection is functioning correctly. Use the PowerShell command from earlier to check that only the new product appears as active in the Security Center.

Step 9: Rebuild Exclusions, Scan Schedules, and Firewall Rules

Using the list from Step 3, manually re-add any exclusions, scheduled scans, and custom firewall rules to ensure that your new antivirus operates smoothly without interruptions.

Step 10: Test Detection Safely With the EICAR File

To confirm that your new antivirus is working correctly, create the EICAR test file, which is designed to be recognized by legitimate antivirus engines. A successful detection will confirm that real-time protection is fully operational.

Phase 4: Scale and Document (Steps 11 to 13)

Step 11: Migrate Every Family or Business Device

Repeat the migration process on each device covered by your license, one at a time. This approach allows you to troubleshoot any issues that arise without affecting all devices simultaneously. For households using ESET HOME Security, take advantage of the new “Members” model to assign devices to specific family members for easier management.

Step 12: Confirm Account-Level Settings and Login Methods

Log into the new vendor’s account portal on each device to verify your preferred login method. ESET HOME 11.1 introduced passwordless passkey login support, which is worth enabling to avoid future access issues.

Step 13: Document the Migration and Set a Review Date

Record the new product name, version, activation date, renewal date, and covered devices. Set reminders to check on subscription renewals and pricing changes to avoid surprises down the line.

Common Pitfalls That Break an Antivirus Migration

Many failed migrations can be traced back to a few common mistakes. Be vigilant for the following:

• Installing the new antivirus before fully removing the old one: This can lead to conflicts between two real-time engines.
• Forgetting to disable self-defense/tamper protection: This can prevent the uninstaller from functioning properly.
• Skipping the vendor removal tool: Standard uninstallers often leave behind crucial components.
• Losing exclusion lists: Ensure all necessary exclusions are documented and re-added.
• Not checking for license conflicts: Be aware of auto-renewals that may lead to double billing.
• Assuming built-in protection will cover gaps: Windows Defender may not activate immediately after uninstalling a third-party product.
• Migrating all devices at once: This can complicate troubleshooting if issues arise.
• Ignoring mobile and tablet licenses: Ensure all devices under the same subscription are updated.
• Trusting dashboard status over actual detection tests: Always verify functionality with the EICAR test.

Output Examples: What a Clean Migration Looks Like

To confirm a successful migration, utilize the Security Center query and other checks to ensure that only the new antivirus product is active and functioning correctly. The expected output should indicate that Windows Defender is disabled, confirming that the new product has taken over primary responsibility.

Switching Antivirus on Android and iOS Devices

The guidelines above primarily address desktop operating systems, but many antivirus licenses also cover mobile devices. When switching on Android, ensure that any accessibility or device-admin permissions from the old app are cleared to avoid conflicts. On iOS, the process is simpler, typically involving the deletion of the old app and signing into the new one. Always check that mobile devices are linked to the same household or business account to maintain coverage.

Advanced Tips for Power Users and Small Teams

For those managing multiple devices, consider staggering the migration over several days to ensure a smooth transition. Utilize the migration as an opportunity to reassess your security posture and confirm that the new product meets your organization’s needs. Additionally, check for any advisories affecting your antivirus vendors before committing to a migration window.

Complete Working Project: A Reusable Migration Runbook

To streamline future migrations, save the following PowerShell script, which checks the current antivirus state and logs it for comparison:

# av-migration-check.ps1
Run as Administrator before AND after switching antivirus software
Produces a timestamped log for pre- and post-migration state

$logPath = "$HOMEDesktopav-migration-log.txt"
$stamp = Get-Date -Format "yyyy-MM-dd HH:mm:ss"

"=== Antivirus check: $stamp ===" | Out-File -FilePath $logPath -Append

$avProducts = Get-CimInstance -Namespace root/SecurityCenter2 -ClassName AntiVirusProduct
$avProducts | Select-Object displayName, productState |
    Out-File -FilePath $logPath -Append

$defenderStatus = Get-MpComputerStatus |
    Select-Object AntivirusEnabled, RealTimeProtectionEnabled
$defenderStatus | Out-File -FilePath $logPath -Append

if (($avProducts | Measure-Object).Count -gt 1) {
    "WARNING: more than one antivirus product detected. Resolve before continuing." |
        Out-File -FilePath $logPath -Append
} else {
    "OK: exactly one antivirus product detected." | Out-File -FilePath $logPath -Append
}

Write-Host "Migration check complete. Log saved to $logPath"

Running this script before and after the migration on each device will provide documented proof of a successful transition to a single-engine, fully protected state.

Frequently Asked Questions

Do I need to uninstall my old antivirus before installing a new one?
Yes. Running two real-time antivirus engines simultaneously can cause performance issues and system instability. Always remove the old product completely, reboot, and then install the new one.

Will Windows Defender protect my PC during the gap between uninstalling and installing?
Windows Defender typically reactivates automatically when no other antivirus is detected, but this may require a reboot. Keep this window as short as possible.

What is the safest way to test that my new antivirus is actually working?
Use the EICAR standard test file, which is designed to be flagged by legitimate antivirus engines. It contains no real malicious code and is the industry-standard method for confirming real-time detection.

Can I just use the built-in Windows or Mac uninstaller instead of the vendor’s removal tool?
While you can try, standard uninstallers often leave behind low-level drivers and scheduled tasks. Using the vendor’s dedicated removal tool ensures a thorough cleanup.

What happened to ESET’s old product names like Internet Security and Smart Security Premium?
ESET has rebranded its home lineup, replacing those names with ESET HOME Security Essential and Premium, with the Ultimate and Small Business Security tiers now including automatic ransomware backup and restoration.

Is IPVanish’s new antivirus a separate product I need to install on top of the VPN?
No. IPVanish has integrated its October 2026 antivirus release directly into its existing desktop VPN application, eliminating the need for a separate download.

How often should I actually switch antivirus software?
Most users should not switch reflexively. Changes should be made when specific needs arise, such as feature gaps or pricing changes, rather than on a fixed schedule.
