A vulnerability has been reported in Microsoft Windows, which can be exploited by malicious people to spoof certain information and potentially trick a user into installing a malicious program.

The vulnerability is caused due to an error in Microsoft Agent making it possible to spoof trusted Internet content (e.g. hide various security prompts by a Microsoft Agent character). This can be exploited to trick a user into believing that they are looking at trusted content when actually visiting a malicious web site.

Successful exploitation requires that a user visits a malicious web site.
