2.594.00 is not the magic number
Trend Micro forced to apologise to customers for faulty update file.
A red-faced Trend Micro has apologised to its customers for the release of a faulty update file that caused chaos for thousands of computer users worldwide.
Official Pattern Release 2.594.00, released in the morning
of Saturday 23 April (Japanese time), caused 100% CPU
usage, system slow down, and in some cases complete
system failure on machines running Windows XP SP 2 and
Windows 2003 Server.
Although Trend staff removed the file
from the Active Update list just 90 minutes later, the
company estimated that it had already been downloaded
between 300,000 and 350,000 times and support staff are
reported to have received in the region of 370,000 calls
about the problem. The fault was blamed on insufficient
testing of the pattern file in the rush to add detection of the
Rbot family of worms.
To add to its woes, Trend’s share
price took a knock, falling 4.7 per cent, and it is expected
that the incident will have an adverse effect on the
company’s second quarter results.
