Catching a nasty virus
There are a host of new crimes that can only happen because of computers, such as viruses, where people write pieces of computer code that download themselves, often as email attachments, onto your computer. These viruses then often access your address books and send copies of themselves onto your contacts. Some of them even destroy data on your computer first. Like a biological virus these electronic nasties duplicate themselves and spread rapidly over the Internet. They have caused millions of pounds of damage in the business world.
