Real-time protection, on-demand scans, quarantine and Game Mode for one Windows PC.
Adds scheduled scanning, automatic removable-drive checks and wider file coverage for PCs used every day.
For users who want Kraken’s deepest local scans, startup checks, integrity verification and shortest definition interval.
Turn it on before a game or other latency-sensitive workload. Kraken reduces non-urgent background activity while real-time protection remains enabled, then returns to the normal profile when Game Mode is switched off.
I wanted an antivirus I could leave running on a gaming PC without babysitting it. It needed useful protection when the connection dropped, controls that were easy to find, and a way to stay quiet during a game without turning protection off.
Those are still the three checks I use when deciding what belongs in Kraken AV.
