Trend Micro is still suffering financial and customer relations repercussions nearly a week after issuing a faulty virus definition file that caused customers' PCs to slow to a crawl. The Tokyo-based security firm's stock has taken a hit. An investment firm has downgraded the stock, and the company acknowledges the incident may affect corporate earnings in the second quarter.
The problem began last Friday afternoon when Trend Micro pushed out a flawed virus signature update that caused computers, primarily those running Windows XP SP2, to lock up as the software consumed 100 percent of the processor's cycles.
