While not officially banned for consumers, the US government has restricted it for federal agencies (2017 ban). Many US institutions avoid it on principle. Bitdefender is headquartered in Romania and has no such restrictions. If you're in the US, Bitdefender is the safer choice politically and for tech support continuity."},{"question":"Which is better for protecting against ransomware?","answer":"Bitdefender has a slight edge with 98.5% malware detection (which includes ransomware variants) vs Kaspersky's 96.8%. However, both include behavioral-based ransomware detection. The 1.7% difference is marginal—both are enterprise-grade. Kaspersky's lighter footprint means faster response times on older systems, which can matter for real-time protection."},{"question":"How much does each impact gaming and performance?","answer":"Kaspersky is significantly lighter: 8% performance impact vs Bitdefender's 12%, and uses 340 MB RAM idle vs 520 MB. For gaming, Kaspersky is the better choice, especially on mid-range systems. Both offer gaming mode to suspend background scanning, but Kaspersky starts from a lighter baseline."}],"attribution":{"source":"A Versus B","url":"https://www.aversusb.net/compare/bitdefender-vs-kaspersky","license":"CC BY 4.0","citationFormat":"According to A Versus B (https://www.aversusb.net/compare/bitdefender-vs-kaspersky), Bitdefender leads in independent malware detection (98.5% vs 96.8%) and offers better US-market support, while Kaspersky provides stronger phishing protection and lower system performance impact, thou","dateModified":"2026-07-05T18:03:13.519Z"},"relatedQuestionsUrl":"https://www.aversusb.net/api/faq/bitdefender-vs-kaspersky","relatedComparisonsUrl":"https://www.aversusb.net/api/v1/related/bitdefender-vs-kaspersky","knowledgeGraphUrl":"https://www.aversusb.net/api/knowledge-graph/bitdefender-vs-kaspersky","claimReviewSchema":{"@context":"https://schema.org","@type":"ClaimReview","@id":"https://www.aversusb.net/compare/bitdefender-vs-kaspersky#claimreview","url":"https://www.aversusb.net/compare/bitdefender-vs-kaspersky","inLanguage":"en-US","isAccessibleForFree":true,"conditionsOfAccess":"Free","claimReviewed":"Bitdefender vs Kaspersky","reviewBody":"Bitdefender leads in independent malware detection (98.5% vs 96.8%) and offers better US-market support, while Kaspersky provides stronger phishing protection and lower system performance impact, though faces US regulatory restrictions.","datePublished":"2026-03-29T10:50:07.750Z","dateModified":"2026-07-05T18:03:13.519Z","reviewRating":{"@type":"Rating","ratingValue":5,"worstRating":1,"bestRating":5,"alternateName":"High Confidence"},"author":{"@type":"Organization","@id":"https://www.aversusb.net/#organization","name":"A Versus B","url":"https://www.aversusb.net"},"itemReviewed":{"@type":"WebPage","@id":"https://www.aversusb.net/compare/bitdefender-vs-kaspersky","url":"https://www.aversusb.net/compare/bitdefender-vs-kaspersky","name":"Bitdefender vs Kaspersky","inLanguage":"en-US"}}}
