Google Inc. is offering to run the search engines of small Web sites for as little as $100 per year, marking the company’s latest attempt to make more money off technology that already steers much of the Internet’s traffic.

The service scheduled to be unveiled Tuesday is aimed at the millions of Web sites that either don’t have search engines or are unhappy with the quality of their current search results, said Nitin Mangtani, a Google product manager.

The price for Google’s “Custom Search Business Edition” will start at $100 annually to sift through up to 5,000 Web pages. Larger Web sites can pay Google $500 annually to search up to 50,000 Web pages.

Microsoft Corp. is once again on the defensive against hackers after the launch of a new program that gives average PC users tools to unlock copy-protected digital music and movies.

The latest version of the FairUse4M program, which can crack Microsoft’s digital rights management system for Windows Media audio and video files, was published online late Friday. In the past year, Microsoft plugged holes exploited by two earlier versions of the program and filed a federal lawsuit against its anonymous authors. Microsoft dropped the lawsuit after failing to identify them.

The third version of FairUse4M has a simple drag-and-drop interface. PC users can turn the protected music files they bought online - either a la carte or as part of a subscription service like Napster - and turn them into DRM-free tunes that can be copied and shared at will, or turned into MP3 files that can play on any type of digital music player.

An Iranian hard-line student group unveiled a new video game Monday that simulates an attempt to rescue two Iranian nuclear experts kidnapped by the U.S. military and held in Iraq and Israel.

The “Rescue the Nuke Scientist” video game, designed by the Union of Students Islamic Association, was described by its creators as a response to a U.S.-based company’s “Assault on Iran” game, which depicts an American attack on an Iranian nuclear facility.

“This is our defense against the enemy’s cultural onslaught,” Mohammad Taqi Fakhrian, a leader of the student group, told reporters Monday.
