Can I use Trojan Killer in my language? Change the Trojan Killer interface language, understand what the setting affects, and report missing or unclear translations.
Do I need internet to use the app? Learn which Trojan Killer tasks work offline and when activation, Threat List updates, website checks, or Support features need a connection.
Does Trojan Killer work with other antivirus apps? Use Trojan Killer alongside another security product while avoiding duplicate real-time filters, simultaneous scans, and unsafe exclusions.
How do I send Support the info you need? Prepare a focused Gridinsoft Support request with the right report, timestamps, environment details, and safely redacted account information.
I have a valid license but the key isn’t working. Troubleshoot a valid Gridinsoft key that is rejected by checking the exact error, purchase account, connection, clock, and activation limit.
I have a virus but Trojan Killer doesn’t detect it. Update Trojan Killer, run the appropriate scan, verify whether the symptom is malware, and send a focused diagnostic report or sample to Support safely.
I think a detection is a false positive. What should I do? Keep a suspected file detection isolated and send it to Support; submit website and domain reputation cases through Gridinsoft Portal.
The Portable Edition asks me to activate again. Troubleshoot repeated Trojan Killer Portable activation after a USB, folder, hardware, clock, connection, or device-assignment change.
What exactly does Reset Browser Settings change? Understand each browser and Windows setting that the reset tool can change, what is selected by default, and how to protect personal browser data.
What information do you collect? Understand the difference between service data, optional diagnostics, manual Support submissions, and information that should never be included.
What scan should I start with? Choose Quick, Standard, Full, or Custom scanning based on symptoms, exposure, available time, and the location you need to check.
What’s different about the Portable Edition? Compare Trojan Killer Portable with an installed security app, including USB use, updates, activation, real-time limits, and safe handling.
Why does the app ask me to reboot after cleanup? Understand why cleanup may require a Windows restart, how to prepare safely, and what to do when the same reboot request or detection returns.
