The biggest problem is that the most recent batch of viruses and Trojan horse programs have used e-mail to multiply the damage. Both Melissa and Love Bug copied themselves into users' e-mail address books, automatically sending themselves on when the victim logged on to the Net. But it is interesting to note that they are only two of around 50,000 viruses in circulation. Before you start to panic, consider for a moment how many human viruses and bacteria you encounter every day of the week. But a normal healthy person doesn't need to stay indoors to avoid them.
Sensible precautions are the answer.
It's the same with computers. Any company trading online should have an effective firewall to prevent infection. If you haven't, put one in place immediately. Home and small business users should install anti-virus software and update it regularly. Several companies claim to have zapped the Love Bug within minutes of its appearance.
