Free Antivirus FAQ

Will Loaris conflict with my existing antivirus?
No. Loaris Trojan Remover is an on-demand scanner, not a real-time antivirus. It only runs when you start a scan, so there's no conflict with your existing security software like Windows Defender, Avast, Kaspersky, or any other antivirus.
Why do I need a second antivirus?
No single antivirus catches 100% of threats. Different scanners use different detection methods and signature databases. Running a second opinion scanner like Loaris helps catch malware that your primary antivirus might miss.
Is it really free?
Yes! You can download Loaris and run a full system scan completely free of charge. The free version detects and shows you all threats. You can upgrade to remove threats automatically and get priority support.
Should I uninstall my current antivirus?
Absolutely not. Keep your current antivirus for real-time protection. Loaris is designed to complement your existing security, not replace it. Think of it as a specialist consultant, not a replacement doctor.
