Windows fails second virus test
Microsoft's Live OneCare security software has failed tests which check how well it spots and stops malicious programs designed to attack Windows. — OneCare was the only failure among 17 anti-virus programs tested by the AV Comparatives organisation.
Context & Ripple Effects
Windows Live OneCare has had a rough first year in public. Before it even shipped, Microsoft's OneCare firewall drew fire from testers in February 2006, and the package finally reached market that August with a launch splash built on its all-in-one promise: antivirus, backup, tune-up, and firewall in one subscription.
Now AV Comparatives' malware-detection benchmark delivers the sharpest rebuke yet: among 17 anti-virus programs tested, OneCare was the only one to fail at spotting and stopping malicious programs aimed at Windows. That matters because OneCare is not an also-ran utility — it is Microsoft's own security offering for its own operating system, sold on the premise that the platform vendor knows best how to protect it.
First-order effects
- Customers paying for OneCare are running the worst-tested malware detection in a 17-product field, undermining the product's core value proposition on Microsoft's flagship OS.
- AV Comparatives gains outsized influence over purchase decisions: a single 'fail' verdict against the incumbent's own product is the strongest possible advertisement for the other sixteen.
Second-order effects
- Rival security vendors in the tested field can now market against the platform owner directly — 'independent labs rate us, not Microsoft' — pressuring Microsoft to fix detection rates fast or discount OneCare to hold subscribers.
- The result sharpens the question facing every Windows buyer: whether to buy security from the OS vendor itself or from third-party specialists whose products just outperformed it in the same test.
Third-order effects
- Independent testing organizations like AV Comparatives are consolidating their role as de facto certification authorities for the consumer security market, with pass/fail verdicts capable of making or breaking a product regardless of brand strength.
- If Microsoft keeps competing in security while controlling Windows, expect persistent scrutiny over conflicts of interest between the platform owner and the security suite market built on top of it.
The trend: Consumer antivirus is being sorted by independent lab benchmarks rather than brand trust, a shift that punishes even the platform owner when its own suite underperforms.
