For computer users, a few mouse clicks could mean the difference between staying online and losing Internet connections this summer.

Unknown to most of them, their problem began when international hackers ran an online advertising scam to take control of infected computers around the world. In a highly unusual response, the FBI set up a safety net months ago using government computers to prevent Internet disruptions for those infected users. But that system is to be shut down.

AP) SAN FRANCISCO (AP) — Tax-free shopping is under threat for many online shoppers as states facing widening budget gaps increasingly pressure Amazon.com Inc. and other Internet retailers to start collecting sales taxes from their residents.

Billions of dollars are at stake as a growing number of states look for ways to generate more revenue without violating a 1992 U.S. Supreme Court ruling that prohibits a state from forcing businesses to collect sales taxes unless the business has a physical presence, such as a store, in that state.

SARGODHA, Pakistan – A Pakistani court on Thursday convicted five Americans on terror charges and sentenced each to at least 10 years in prison, a prosecutor said.

They were accused of contacting militants in Pakistan over the Internet and plotting terrorist attacks.

Rana Bakhtiar made the announcement Thursday in the Punjab town of Sargodha. He said the men have the right to appeal.

(CNN) — Former President Clinton said he sees parallels in the mood of the country now and on April 19, 1995, when the bombing of a federal building in Oklahoma City killed 168 people while he was in the White House.

“There’s the same kind of economic and social upheaval now,” he told CNN’s Wolf Blitzer in an interview to air Friday on “The Situation Room.”

“Then, you had the rise of extremist voices on talk radio. Here, you have a billion Internet sites,” Clinton said.

A suburban Philadelphia school district accused of secretly switching on laptop computer webcams inside students’ homes says it never used webcam images to monitor or discipline students and believes one of its administrators has been “unfairly portrayed and unjustly attacked.”

The Lower Merion School District, in response to a suit filed by a student, has acknowledged that webcams were remotely activated 42 times in the past 14 months, but only to find missing, lost or stolen laptops — which the district noted would include “a loaner computer that, against regulations, might be taken off campus.”

Two bloggers received home visits from Transportation Security Administration agents Tuesday after they published a new TSA directive that revises screening procedures and puts new restrictions on passengers in the wake of a recent bombing attempt by the so-called underwear bomber.

Special agents from the TSA’s Office of Inspection interrogated two U.S. bloggers, one of them an established travel columnist, and served them each with a civil subpoena demanding information on the anonymous source that provided the TSA document.

The document, which the two bloggers published within minutes of each other Dec. 27, was sent by TSA to airlines and airports around the world and described temporary new requirements for screening passengers through Dec. 30,

(CNN) — The past 12 months have been a banner year for cyber crime. And that could be bad news for the future of e-commerce.

“At current trends, in three or four years people will start to think twice about transacting on the Web, individuals and businesses,” said Michael Fraser, director of the communications law centre at the University of Technology Sydney.

“The way it’s trending now, the Web could be so full of rubbish that people won’t trust it,” Fraser said. “That could destroy the potential of the whole knowledge economy, which so many developed economies are counting on for the competitive advantage.”

(CNET) — Major countries and nation-states are engaged in a “Cyber Cold War,” amassing cyberweapons, conducting espionage, and testing networks in preparation for using the Internet to conduct war, according to a new report to be released on Tuesday by McAfee.

In particular, countries gearing up for cyberoffensives are the U.S., Israel, Russia, China, and France, the says the report, compiled by former White House Homeland Security adviser Paul Kurtz and based on interviews with more than 20 experts in international relations, national security and Internet security.

WASHINGTON – Stung by an embarrassing electronic leak last month revealing ethics investigations into dozens of lawmakers, Congress moved Tuesday to prohibit federal employees from using the same type of Internet file-sharing software blamed for the disclosure.

The Secure Federal File Sharing Act, introduced in the House, would bar government employees and contractors from downloading, installing or using so-called peer-to-peer file sharing software such as Limewire without official approval. The bill also would require the White House to develop rules for employees and contractors working on home or personal computers.

(CNN) — Ever wonder what information Google knows about you? With a click or two, now you can find out.

Google released a feature Thursday that lets users see and control data that the Web giant has collected about them. Called Google Dashboard, the service provides an online summary of a user’s Google files — Gmail, Google Docs, Picasa photos and so on — by collecting pre-existing privacy controls in one place.

Dashboard users can review and delete recent Google searches, see recently opened and shared documents and survey their interactions with other Google-powered sites such as YouTube.
