Simple and powerful, Norton AntiVirus 2003 protects your PC against viruses--and it covers e-mail and instant messaging, too. The program's clear and simple interface shows you what you're protected against, how up-to-date your virus definitions are, and when you last checked your whole system. Anything you need to worry about is clearly marked in red.
Installation is simple: you can accept all the defaults without worry, and you'll be prompted to go online and get up-to-date definitions as soon as you install. If a virus is found, the software will try to automatically repair the file. In addition to looking for known viruses, the Norton AntiVirus Bloodhound feature tries to spot new viruses and worms by their behavior. AntiVirus 2003 also checks for viruses in files you download from the Web, in e-mail, and now in instant messages. If you use MSN Messenger you'll need to reboot; other messaging tools are protected straight away. With e-mail, Norton AntiVirus 2003 can check incoming and outgoing messages and files in POP3 clients like Outlook Express. While AntiVirus 2002 would only stop you from getting infected by an e-mail worm, this version stops you from passing the infection on to others.
