Computer Viruses

In October 2002, the Bugbear virus infected users running Windows via a security hole in Microsoft Outlook, Microsoft Outlook Express and Internet Explorer. The virus copied itself to the hard drive and on to other computers that shared a network. The virus copied the passwords and credit card numbers a user typed. Then, it could send a file with the personal information to several e-mail addresses. In its first week, 320,000 infected e-mails were sent. Viruses can be stopped by good internet security software and personal firewall software.
