«Companies are clamping down on employees' workplace use of the expanding range of free Internet services, such as instant messaging and video downloading, to protect themselves from viruses, communications traffic jams and regulatory missteps.
General Electric Co. has barred outside instant-messaging and file-sharing programs, as well as access to personal online e-mail accounts such as those offered by Yahoo! Inc. Telecom company Global Crossing Ltd. also blocks outside instant messaging and online e-mail accounts. JPMorgan Chase & Co. is one of many banks that blocks Internet services it can't track or monitor, including outside instant-messaging, phone and e-mail programs.
Another big bank, ABN Amro Holdings NV of the Netherlands, also bans many consumer-communications technologies, including Skype, the Internet phone service owned by eBay Inc.
The corporate crackdown underscores an emerging challenge for the Web. As the spread of broadband technology makes it possible for millions of Americans to watch TV on the Web or make cheap phone calls, companies, government agencies and universities are concerned about the possible side effects — including the threat of a worm or other bit of malicious code sneaking into their computer systems.
