U.S. reader note: The U.S. Department of Commerce prohibits certain Kaspersky cybersecurity and antivirus transactions, including provision and resale, and related updates. This article is a historical comparison, not a U.S. purchase recommendation. See the official BIS information for scope and details.
Malware protection is one layer of defense for devices and personal information. Antivirus tools can monitor, detect, and block threats, but do not replace updates, account security, or backups.
This archived comparison discusses two well-known brands: Avast and Kaspersky.
Background and trust considerations
Kaspersky was founded in 1997 by Eugene Kaspersky in Russia. Its products expanded from antivirus tools into protection against phishing, ransomware, and other threats.
Over time, Kaspersky became a prominent cybersecurity brand internationally. Its Russian connections also prompted government scrutiny and restrictions. For U.S. readers, availability and regulatory restrictions take priority over a historical feature comparison.
Avast was founded in 1988 by Pavel Baudiš and Eduard Kučera in what was then Czechoslovakia. It became known for free antivirus software. It grew through a broad consumer offering and acquisitions, including AVG in 2016. Historically, it was a familiar free antivirus option for Windows 10 and other operating systems.Avast also faced privacy controversy involving its former Jumpshot subsidiary and the sale of browsing data. The company closed Jumpshot in 2020. Trust and data handling are important considerations alongside detection features.
Kaspersky and Avast: features discussed in the original comparison
Features depend on the product, plan, platform, region, and version. Review the exact supported edition rather than relying on a brand-level comparison.
- Threat protection
The original comparison described real-time malware protection, phishing defenses, and behavior monitoring, with additional controls varying by plan. It also discussed family and gaming-related features. Check current independent tests and the specific product documentation before selecting an available product.
- Privacy
The article discussed features such as secure file removal, webcam controls, browsing protection, and exposure alerts. These are not included in every edition, and privacy tools do not establish that a product is appropriate for every market.
- VPN features
VPN services can encrypt part of a connection and change the visible IP address, but do not guarantee anonymity or prevent every form of tracking. Limits, server access, and availability vary by provider and subscription.
- Customer support
The original article described online documentation, community resources, and support channels such as chat, phone, or email, depending on the product and plan.
Support availability and eligibility should be checked for the exact region and service. A historical list of channels is not a guarantee of current support.
Conclusion: choosing antivirus for your region
Do not choose solely on a historical brand comparison. For a U.S. purchase, prioritize products that are available, supported, and suitable for the U.S. market, then compare protection, privacy practices, system compatibility, and total cost.
