Chart: Comparison Article: False Alarm Test September 2026


Hi Spartan, this is a useful companion to the protection chart. Lower is better, and the spread is substantial:

  • 1: Bitdefender, G Data
  • 3–6: ESET, Total Defense, Kaspersky, VIPRE
  • 14–15: F-Secure, Fortect, Avast, AVG, K7, Norton, TotalAV, Trend Micro
  • 28–49: Microsoft, Malwarebytes, McAfee, Quick Heal, Sophos
  • 91: Panda

Taken together with the September Malware Protection Test, Bitdefender has the standout balance: 99.98% online protection with only one false alarm. Kaspersky also looks well balanced at 99.97% with five. Panda’s 91 false alarms are particularly difficult to justify alongside 98.39% protection; that is a lot of noise without a corresponding protection advantage.

The counts still need context. AV-Comparatives counts multiple detections belonging to one application as a single false alarm and excludes cracks, keygens and similarly questionable tools. They are therefore comparative counts from this clean-file set—not percentages or a prediction of how many warnings every user will encounter. The named applications and their prevalence in the detailed false-alarm report matter too. Even so, once the count reaches several dozen, “better safe than sorry” starts becoming “better keep the quarantine log handy.”
