    Trend Micro Antivirus Update Slows PCs

    Faulty file drained the processing power of PCs that had downloaded the update, company says.

    A faulty update to antivirus software released over the weekend by Tokyo-based Trend Micro caused PCs to slow down or stop working around the world, the company says.

    By 2 p.m. local time in Tokyo on Monday, Trend Micro had received 311,900 calls from business and consumer users in Japan saying their PCs had been affected by a faulty data file containing information about known viruses and worms, according to the company. The data file was available between 7:30 a.m. and 9:02 a.m. Tokyo time on April 23, says company spokesperson Naomi Ikenomoto.

    A bug in the file, Official Pattern Release (OPR) 2.594.00, created a loop that sucked up all or nearly all the processing power of PCs that had downloaded the update, she says.

    Business with PCs using Microsoft's Windows XP Service Pack 2 (SP2) and Trend Micro's OfficeScan software, and consumer PCs using Microsoft Windows XP SP2 and Trend Micro's PC-cillin Internet Security 2005 VirusBuster software were affected, Ikenomoto says.

    "The problem was caused by our virus labs in Manila during the checking process when a part of the test wasn't performed," she says.

    The company replaced the faulty file with version 2.596.00 at 10:51 a.m. Japan time. This and later OPRs issued by Trend Micro will automatically end the problem in PCs that download the new files, the company says.

    Affected Users

    The vast majority of those affected by the faulty file were in Japan, although Trend Micro has received several reports of users experiencing problems from Australia and countries in the Middle East and Europe. The company had several hundred calls from customers in the U.S., Ikenomoto says.

    "It was a lot of trouble, I had to go half the day not using my PC," says Yoshimi Machida, a language instructor in Tokyo whose desktop PC was hit by the faulty update at about 9 a.m. Saturday morning.

    The PC slowed to a crawl when downloading e-mail, Machida says. She at first thought either the PC had downloaded a virus through the e-mail software, or that the PC was breaking down. After spending an hour trying to get through to the PC vendor's call center without success, she gave up, switched off her PC and left her house for an appointment she couldn't miss, she says.

    "Initially, I wasn't angry, I was just worried. I couldn't do a thing," Machida says. "Then when I got home in the afternoon and I found out [from the TV news] that it was Trend Micro... then I got angry. Getting a virus is frightening. Every year I pay money to Trend Micro, and then it turned out that they were the cause of this trouble and this is just unbelievable."

    Trend Micro has yet to make any announcement on compensation or other measures for customers affected by the problem. If the company does decide to compensate customers, the details will remain confidential between customers and the company, Trend Micro's Ikenomoto says.
