    Important alert for MetroCast customers!

    Beware of any e-mail that asks you to reveal personal identifying information, including your online logins, user IDs and passwords, even if the email threatens some serious consequence. The email may not be legitimate even though it contains authentic logos and trademarks from companies with whom you regularly do business.

    Responding to such email, or clicking on links within the email that lead to websites, may cause viruses and malicious software to infect your computer. It may also result in the theft of your online credentials and other personal identifying information that could allow cyber criminals to gain unauthorized access to your accounts.

    Please be advised that MetroCast will never ask you by email to provide personal or financial information, your account number, user name or password, or ask you to verify your email. If you suspect that you've received a fraudulent email that appears to be from MetroCast, do not click on it or provide any personal information.

    If you are unsure whether a suspicious email that appears to have been sent by MetroCast is legitimate, you may send it as an attachment or paste it into a new email to
    Please do not forward the email itself. Then, delete the email and empty your deleted email folder.

    If you have received suspicious emails purportedly from other organizations, you may also send the phishing emails (as an attachment) to, as well as to the company, bank, or organization impersonated in the email. You also may report phishing email to The Anti-Phishing Working Group, a group of ISPs, security vendors, financial institutions and law enforcement agencies, uses these reports to fight phishing. You may also file a report with the Federal Trade Commission at Then, delete the email and empty your deleted email folder.
    Spam is a term used to describe any kind of unsolicited online communication, usually email. Sometimes the unwanted online communication is harmless, but it can also be more serious and more dangerous if it is part of a phishing attack.

    Phishing attacks-which may come in the form of "spam" (online junk mail)-attempt to persuade an email recipient to voluntarily provide security credentials or personal identifying information, usually by inviting the recipient to click on a link that leads to a malicious or fraudulent website. The goal of phishing is to steal your personal information and/or to disrupt your computer (and potentially those of others via your computer) through viruses and malware.

    MetroCast utilizes advanced anti-spam filters and virus protections to block the vast majority of fraudulent emails. However, in recent years, cyber-attacks have increased in frequency and sophistication, so harmful emails may still reach recipients' inboxes. For this reason, caution always is advisable.

    A computer virus is a software program or computer code that becomes attached to your computer through email attachments, instant messages, or downloads. The virus is designed to spread from one computer to another and to interfere with your computer's operation and performance. It may also corrupt data on your computer and result in the loss of programs and or saved files.

    Malware is short for "malicious software." It includes viruses and spyware that get installed on your computer, phone, or mobile device without your consent. These programs can interfere with the performance of the device and can be used to monitor and control your online activity. Cyber criminals use malware to steal personal information and commit fraud.

    What does MetroCast do to protect my account from online attacks?

    MetroCast deploys proprietary, state-of-the-art spam filtering which removes the majority of unwanted email before it ever reaches your email inbox. The filtering consists of a multi-stage process using a variety of methods that is over 99% effective. The MetroCast filtering will not interfere with your in-house spam filters, only enhance them. Email that is not clearly spam will be tested and marked as suspected spam based on content. This allows you to set filters for spam that meet your needs. MetroCast also provides virus protection by removing known virus content before it hits your computer or server.

    Proofpoint Spam Filtering and Virus Protections

    As a part of our continuing improvements for our High Speed Internet customers, MetroCast is proud to announce the release of ProofPoint, our new spam and virus removal service. While there are many reasons for MetroCast to make this switch in providers, the single biggest reason is that it is an investment in our customers. Spam is the most frequent complaint in the industry of Internet providers. MetroCast is investing in the highest rated spam tool offered in our industry.

    Our technical support staff is well trained on the product and will be available to answer any of your questions or concerns. A few of the advantages to the service are:

    • The new technology results in a very high spam catch rate while dramatically reducing false positives. Our internal testing has shown approximately a 40% decrease in spam sent to mailboxes versus the previous spam solution.
    • A summary of newly quarantined messages are sent to your mailbox daily. A simple click of the mouse can release the message to your inbox or mail box from the quarantine or whitelist the sender, preventing their mail from being held back to wait for your approval.
    • Email Virus detection with hourly signature updates.

    One of the largest changes is that you, the customer, no longer needs to select and delete the spam items as before. All known spam is automatically deleted and only questionable items will be sent out to the customer for the decision to keep or delete.

    Below is a sample "digest" email from ProofPoint.
    Across the top are links directing server to either:

    • Send a New End User Digest (with all the current email waiting for your approval)
    • Request Safe/Blocked User List to see who is allowed/blocked from sending email
    • Manage My Account will bring you on the server to check settings
    • Help will open a summary screen with detailed information on each function within the digest mailing.

    Now here's the truly important information, so feel free to print this page for reference later.

    • Release will send an email listed on the digest to your email Inbox
    • Safelist will send the email to your Inbox and automatically add to your Safe User list as well.

    Gone are the days of selecting emails just for deletion and virus protection is automatic as well. No more notices announcing that a virus was received. Think of the time saved by not having to read through dozens or hundreds of emails just to delete them each day or week. We heard your concerns and now believe this is a much better solution for the growing spam issues facing our customers.
