Problem
When you try to browse to a website that you believe is trustworthy, the McAfee Firewall function called Net Guard blocks you from accessing the site.
This function uses a repository of known good and known bad domain names and IP addresses. If you try to go to a known bad website or address, Net Guard protects you by blocking the connection.
This article shows you how to file a ratings dispute, and how to allow blocked content.
Solution
If you can’t browse to a website that you think is trustworthy, follow these steps:

Check to see the rating of the website from the TrustedSource homepage:

  1. Open a web browser, and go to trustedsource.org.
  2. On the Check Single URL screen:
    1. In the Please Select drop-down list, select McAfee Real-Time Database.
    2. Type the domain nameURL, or IP address in the textbox, and then click Check URL.
  3. Review the categorization. If you do not agree with the categorization, follow the steps below to submit a dispute.

How to submit an IP reputation dispute
If you think that the rating is a false positive, submit a “change request” as follows:

  1. View the categorization as described above.
  2. Below the categorization details, add up to three categorization suggestions that you believe are more appropriate.
  3. Type an optional comment in the space provided.
  4. Click Submit URL for Review.

If you need to access the page while the page is under review, follow the steps in the workaround below.

Workaround
If you need to connect to this website, you can change the website or IP address to Allow under Net Guard:

IMPORTANT: McAfee recommends that you keep Net Guard enabled, and strongly advises you to wait for the site to be retested instead of changing the site to Allow. The site might have become compromised, and connecting to it could risk your computer security. If you accept this risk and still prefer to access the potentially harmful site, follow these steps:

  1. Open McAfee.
  2. Click Web and Email Protection or click the Gear icon in the upper-right corner.
  3. Select Firewall, scroll down, and then click Net Guard.
  4. Select the IP Address listed for the site that you want to access.

    NOTE: To identify the IP address by name, you need to use a DNS or IP address lookup tool.

  5. Click Edit, and then change Block to Allow.
  6. Click Save or Apply.
NOTE: After the website is reviewed and the status changes, you can remove it from your list by selecting the item and clicking Delete. If the status remains untrustworthy, the IP address will be blocked again. You must use the steps above for any untrusted IP addresses.

DNS and IP lookup tools
While URLs and domain names allow you to more easily remember and access web resources, your connection to these resources uses IP addresses.

Net Guard also uses the IP addresses to control access. If you find multiple IP addresses in the IP Address field, use a lookup tool to find the specific IP address that you need to update.

Common lookup tools include:

Windows XP and Windows Vista
