Internet Explorer

Internet Explorer 8's new SmartScreen Filter builds upon our leadership in the detection of phishing sites and now helps protect you against inadvertent installation of malware—or malicious software—which can compromise your data, privacy, and identity while also damaging your computer and valuable data. Today Internet Explorer is detecting over 1 million attempts to visit known phishing sites weekly.

QuickTime

A really good media Player, QuickTime 7 Player supports a wide-range of industry-standard audio formats including AIFF, WAV, MOV, MP4 (AAC only), CAF and AAC/ADTS. Ultra-efficient, the H.264 codec compresses video tightly, resulting in much smaller files, without sacrificing any quality.

Google Earth

Google Earth is a map viewer with almost every points of this planet. You can change the visualization angle, position and zoom, from entire globe to street level! And that's not all, you are able to search for places of interest, with information and metadata, and the capability to switch on/off the different map layers available (streets, places, 3D maps, roads, borders and labels, etc).
