Version 25.4​

Released May 2025

ARM64 upgrades resumed​

Clients running Total PC version 19.8 on ARM64 will be automatically upgraded to this version. We are still working on adding ARM64 support for the VPN.

Manual banking protection activation​

You can manually activate banking protection on specific websites by adding them to a custom Banking list under Scam Protection → Manage allowed and blocked websites.

Other improvements​

• Alert is shown in the main user interface when a conflicting product has been installed that completely prevents Device Protection from functioning.
• In App and file control user interface, SHA256 hashes of quarantined files are visible and can be copied to the clipboard. Full file paths can also be copied.
• VPN Hydra and WireGuard tunnel adapters are named FSVpnSDK-HydraTunnel and FSVpnSDK-WireGuardTunnel.
• User interface framework updated from .NET6 to .NET8.
• On Settings → Updates user interface, the Device Protection update installation time shown reflects the installation time of the latest new update instead of the last update check time.

Bug fixes​

• Fixed an issue where Device Protection updates could fail with certain firewall configurations.
• Improved recovery in cases where Device Protection malfunctioned.
• Fixed an issue where UDP server could get incorrectly blocked.
• Resolved a problem where VPN Hydra connection establishment could take over 30 seconds.
• Fixed VPN WireGuard connection failures caused by link-local IPv6 DNS servers in the system network configuration.
• Fixed an issue where the VPN trusted network setting did not work correctly after a VPN upgrade.
• Fixed VPN bypass not working when the application path contained certain uppercase Unicode characters.
• Fixed an issue where the virus scan did not always display the name of the currently scanned file.
• Fixed an issue where network connectivity was broken after system returned from sleep or connected standby while VPN was connected.
• Resolved a crash that could occur when opening the hamburger menu in the main user interface.
• Fixed an issue where touch screen-based scrolling did not work on ARM64 devices.

conflicting product installations

is just a way to discourage you from running the competitions' products. Useless feature. Maybe a conflict is noticed at some point in the past, but they never bother to update this warning if the situation changes. I have had enough of this kind of warnings. It's MY computer and I insist on installing what I want and I will deal with the consequences. I am not a stupid end user who gets frightened with one or two error messages.When something breaks, it is something specific that breaks; and if i don't need it then I will let it break all it wants.
