Microsoft is urging Windows users who browse the Web with Internet Explorer to use a free tool called EMET to block attacks against a newly-discovered and unpatched critical security hole in IE versions 7, 8 and 9.

Malicious computer code that leverages a newly-patched security flaw in Oracle’s Java software is set to be deployed later this week to cybercriminal operations powered by the BlackHole exploit pack.
