Separately, Adobe has a new version of its Flash Player software available that squashes at least seven nasty bugs.

Last week, Google security researcher Tavis Ormandy reported to Microsoft a flaw in its Malware Protection Engine, a technology that exists in most of Redmond’s malware protection offerings — including Microsoft Forefront, Microsoft Security Essentials and Windows Defender. Rather than worry about their malicious software making it past Microsoft’s anti-malware technology, attackers could simply exploit this flaw to run their malware automatically once their suspicious file is scanned.

But Google security research Tavis Ormandy discovered that it was possible to add URLs to that whitelist.
