WASHINGTON
Considering the serious warnings lately about Internet viruses, users may be tempted to unplug their machines just to keep them safe. In reality , common sense and a few basic tips can keep Internet surfers secure.
Antivirus software is a must, and it should be updated （更新） at least once a week to recognize newly released （释放的） viruses.
People with broadband Internet connections should also have a firewall. These protect the computer from attacks by hackers.
Then it is time to think about computer habits. Unlike old viruses, which spread only through shared diskettes , the Internet brings viruses straight to the e-mailbox. If an e-mail with attachment comes from an unknown sender, or unexpectedly from a known sender, it should not be opened.
On receipt of an unexpected attachment from a friend, experts suggest a telephone call to make sure of the mail's source before opening.
