Every week we ask ChatGPT, Gemini and Perplexity “What is the best antivirus software?” — the same question, five times per engine, under one fixed condition. Score = how often a name appears in the answers; n/5 = mentioned in n of 5 runs per engine.
Sources shown are the citations the engines consulted for the answers that named each business. Placement is never for sale. Week-over-week movement appears as runs accrue. Full method.
