Frequently Asked Questions

Kaspersky Internet Security costs $39.99 annually (2026), while ESET Internet Security is $49.99—a $10 annual difference favoring Kaspersky. However, ESET's lighter system footprint may reduce performance-related costs on older devices, and adding VPN/password manager to ESET increases its total cost.
ESET is significantly better for resource-constrained systems. It uses only 8-12% CPU during scans (vs Kaspersky's 15-18%), consumes 85-95 MB idle memory (vs 120-140 MB), and completes full system scans in 42 minutes instead of 68 minutes. This makes ESET ideal for users with budget laptops, netbooks, or aging desktops.
Yes, but only in Kaspersky Premium tier (2026). The base Kaspersky Internet Security does not include these features. ESET requires separate purchases for both VPN and password manager add-ons, making Kaspersky Premium better value if you need all three security tools integrated.
Kaspersky achieved 99.8% detection rate in 2025 AV-TEST benchmarks, compared to ESET's 99.2%. While both are excellent, Kaspersky's 0.6 percentage point advantage means it catches approximately 6 additional threats per 1,000 samples, making it better for maximum threat protection.
Kaspersky provides significantly faster support with 2-3 hour response times, compared to ESET's 4-6 hour window. For users who need immediate assistance with security issues, Kaspersky's faster support response is a measurable advantage.
