Responding to emergencies

If you have an emergency, these procedures can help you find the solution to your problem.

If you think your computer is under attack

If your computer is behaving unpredictably, and you have determined that the behavior is not due to a virus or a corrupted file, you may be the victim of an Internet attack.

If you suspect that someone is attacking your computer, immediately disconnect your computer from the Internet. If you have not yet installed Norton Personal Firewall, install it now.

See “Stop Internet

communication with Block Traffic”

on page 44.

If you have installed Norton Personal Firewall, you can use its security tools to block the attack, investigate the attacker, and prevent this type of attack in the future.

To block and investigate an attack

1 Open Norton Personal Firewall.

2 Click Block Traffic.

This immediately stops all incoming and outgoing communication

with other computers.

3 If you are using the Security Monitor, click Security Center.

4 In the Security Center, click Statistics.

5 Click Attacker Details.

Your browser opens the Visual Tracking Web page.

Responding to emergencies

Recover from an emergency

See “Identify the

source of communications”

on page 43.

6 Use Visual Tracking to identify the IP address of the computer that the

attacker used. You can use this information to report the attack to the ISP that owns the IP address.

See “Restrict a

blocked computer”

on page 88.

7 To block all future connections from this IP address, add this computer

to your Restricted Zone.

If you suspect that the attacker has already compromised your computer, install Norton Personal Firewall, then visit http://security.symantec.com for tools to repair damage and eradicate any threats that the attacker may have placed on your computer.

Recover from an emergency

Once you’ve dealt with the problem, you can install Norton Personal Firewall and perform the following activities.

Action Description

Install Norton Personal Firewall.

Update your protection.

Norton Personal Firewall can keep your computer safe from future attacks.

See “Installing Norton Personal Firewall” on page 19.

After installing, run LiveUpdate to ensure that you have the most updated protection.

See “Keeping current with LiveUpdate” on page 53.

Configure your firewall.

Periodically review program logs and statistics.

The default installation of Norton Personal Firewall should provide sufficient protection for most users, but you can customize protection by adjusting firewall settings.

See “Customize firewall protection” on page 72.

Norton Personal Firewall maintains extensive logs of all of the actions that it takes to protect your computer. Check these logs occasionally to identify potential problems.

See “Monitoring Norton Personal Firewall” on page 103.

Prevent future problems

Norton Personal Firewall can protect your computer against most Internet attacks.

To prepare your computer for emergencies:

1 Stay informed about security risks by visiting the Symantec Security

Response Web site (securityresponse.symantec.com).

1 Keep your browser up-to-date. Software publishers release new

versions to fix vulnerabilities in their browsers.

1 Use passwords intelligently. For important information, use complex

passwords that include uppercase and lowercase letters, numbers, and

symbols. Don’t use the same password in multiple places.

1 Don’t run software if you don’t trust the publisher and the source from

which you received the software.

1 Don’t open email attachments unless you are expecting an attachment

and you trust the sender.

1 Be sensible about providing personal information. Many sites ask for

more information than they need.

1 Review the privacy policies of the sites to which you are considering

sending information.

1 Tell children never to reveal details about themselves to people they

meet via instant messenger programs.

1 Back up files regularly and keep copies of the last few backups on

hand.
