The virus is causing something akin to panic throughout corporate America, which has become used to the typos, misspellings, missing words and mangled syntax so acceptable in cyberspace. The CEO of LoseItAll.com, an Internet startup, said the virus had rendered him helpless. “Each time I tried to send one particular e-mail this morning, I got back this error message: ‘Your dependent clause preceding your independent clause must be set off by commas, but one must not precede the conjunction.’ I threw my laptop across the room.” . . . If Strunkenwhite makes e-mailing impossible, it could mean the end to a communication revolution once hailed as a significant timesaver. A study of 1,254 office workers in Leonia, N.J., found that e-mail increased employees’ productivity by 1.8 hours a day because they took less time to formulate their thoughts. (The same study also found that they lost 2.2 hours of productivity because they were e-mailing so many jokes to their spouses, parents and stockbrokers.) . . . “This is one of the most complex and invasive examples of computer code we have ever encountered. We just can’t imagine what kind of devious mind would want to tamper with e-mails to create this burden on communications,” said an FBI agent who insisted on speaking via the telephone out of concern that trying to e-mail his comments could leave him tied up for hours.
