CyberDefender Customer Service: Support, Billing & Reviews

CyberDefender is a cybersecurity name currently included in the RealDefense LLC family of software, services, and websites. Customers looking for CyberDefender support may need help with an older software purchase, account or subscription question, cancellation, renewal charge, refund, technical problem, or a suspicious message claiming to provide CyberDefender or RealDefense support.

The current CyberDefender.com website focuses primarily on scam-awareness and scam-detection training. Customers with older CyberDefender software or subscription issues should use current RealDefense support resources rather than relying on telephone numbers or addresses found in old CyberDefender listings.

How to Contact CyberDefender Customer Service

CyberDefender does not currently publish a dedicated CyberDefender customer-service telephone number on its main website. RealDefense LLC’s current legal terms identify CyberDefender software and CyberDefender.com as part of the RealDefense product family and state that standard customer and technical support for RealDefense products is offered through USTechSupport.

For account, subscription, cancellation, or other product questions, RealDefense’s current terms also publish support@realdefen.se and refer customers to online chat or the contact form for the relevant product.

The number 1-801-857-2345 is specifically published by RealDefense for qualifying standalone-software refund requests. It should not be treated as a general CyberDefender technical-support number.

CyberDefender, RealDefense and the Older CyberDefender Corporation

Older consumers may remember CyberDefender as a company selling antivirus, anti-malware, PC optimization, online backup, and remote technical-support services. That business operated as CyberDefender Corporation and used Los Angeles addresses including locations on West 7th Street.

CyberDefender Corporation filed for Chapter 11 protection in 2012 as part of a proposed sale of substantially all of its assets to GR Match, LLC, an affiliate of Guthy-Renker.

The current situation is different. RealDefense LLC’s current Terms of Service and Privacy Policy specifically include CyberDefender among RealDefense software products and list CyberDefender.com among websites RealDefense may operate.

For that reason, customers should not assume that a support number, corporate officer, mailing address, refund policy, or software instruction from the old CyberDefender Corporation remains valid today.

What to Have Ready Before Contacting CyberDefender or RealDefense

• The name of the CyberDefender or RealDefense product involved
• The email address associated with the purchase or account
• Your order or transaction number
• The purchase or renewal date
• The amount charged
• The exact billing descriptor shown on your statement
• The device and operating system involved
• An error message or error code, when applicable
• A previous support case or chat number
• The website or retailer that processed the purchase
• The specific cancellation, refund, billing correction, or technical resolution you want

Do not send passwords, complete payment-card numbers, Social Security numbers, authentication codes, remote-access credentials, or other unnecessary sensitive information through ordinary email.

How to Cancel a CyberDefender or RealDefense Subscription

RealDefense’s current terms state that subscription billing continues until the account is canceled or terminated.

For a subscription purchased directly from RealDefense or one of its product sites, the current terms direct customers to use support@realdefen.se, online chat, or the contact form available for the relevant product.

When canceling:

1. Identify the exact product or subscription.
2. Check which company processed the original payment.
3. Contact the official support route.
4. State clearly that you want recurring billing canceled.
5. Ask for the effective cancellation date.
6. Request written confirmation.
7. Save the confirmation until you are sure no additional renewal is charged.

Uninstalling cybersecurity software from a computer should not be assumed to cancel a paid subscription. Confirm the billing status separately.

Third-Party Purchases

If CyberDefender or another RealDefense product was purchased through a third party, RealDefense’s terms say the customer generally must cancel directly with that seller. This can include a retailer, payment platform, app marketplace, software reseller, or other company that processed the transaction.

Review the original receipt and your payment statement before contacting support so you know which business actually billed you.

CyberDefender Automatic Renewal and Unexpected Charges

RealDefense’s current terms state that subscriptions can include recurring payment obligations. For annual or longer subscriptions, RealDefense may attempt to process a renewal payment as early as 35 days before the subscription expiration date.

If you see an unexpected CyberDefender or RealDefense-related charge:

1. Check the exact statement descriptor.
2. Search your email for purchase and renewal confirmations.
3. Review any RealDefense, CyberDefender, iolo, USTechSupport, or related account you recognize.
4. Determine whether another household member made the purchase.
5. Verify whether the transaction was processed by RealDefense or a third-party seller.
6. Contact the appropriate official support route.
7. Ask whether the subscription is still set to renew.
8. Save any cancellation or refund confirmation.

If the company cannot identify the transaction and you believe the charge is unauthorized, contact your bank or payment-card issuer promptly about account security and dispute procedures.

CyberDefender Refund Requests

RealDefense’s current Terms of Service state that qualifying purchases of standalone software may receive a refund when the customer contacts RealDefense within 30 days of purchase.

The published refund number for standalone software is 1-801-857-2345. RealDefense states that approved refunds are returned to the original form of payment.

The terms also say that monthly, quarterly, annual, and other subscription charges are generally nonrefundable except where another provision or applicable law provides otherwise. Refund eligibility can therefore depend on what was purchased, how it was purchased, and the specific transaction.

When requesting a refund, have the order information, purchase date, amount, product name, and reason for the request available. Do not post that information publicly.

CyberDefender Technical Support

RealDefense’s current terms say standard customer and technical support for RealDefense products is provided through USTechSupport. The service may assist with account or subscription questions and supported RealDefense products.

For a software problem, prepare:

• The exact product name
• Your operating system and version
• The software version, when available
• The precise error message
• What happened immediately before the problem
• Whether another antivirus or security product is installed
• Any troubleshooting steps already attempted

Back up important files before allowing any company to make substantial changes to a computer. RealDefense’s remote-service terms state that customers are responsible for maintaining their own backups before remote technical work.

Remote Technical Support Safety

If someone claims your computer has a virus, security failure, expired subscription, or urgent technical problem:

• Do not call a number displayed in a suspicious pop-up.
• Do not install remote-control software solely because a stranger requests it.
• Do not provide online-banking credentials or card-security codes.
• Do not purchase gift cards or cryptocurrency to pay for technical support.
• Close the message and navigate independently to the official website.
• Verify the support provider before allowing remote access.

If an unknown person already accessed your computer remotely, disconnect the device from the internet, contact affected financial institutions if payment information was exposed, change important passwords from a trusted device, and run security checks using legitimate software.

Current CyberDefender Website

The current CyberDefender.com website focuses on helping visitors practice spotting common online scams, including phishing emails, suspicious text messages, fake websites, and questionable social-media messages.

This differs significantly from older descriptions of CyberDefender as primarily a traditional antivirus and PC-support company. Customers looking for support for an older CyberDefender purchase should therefore use the current RealDefense support framework rather than assuming that the present CyberDefender homepage contains every legacy account-support function.

CyberDefender Corporate Information

Current RealDefense materials identify CyberDefender as part of the RealDefense product and website family.

RealDefense LLC lists its headquarters as:

RealDefense LLC
6080 Center Dr
Suite 800
Los Angeles, CA 90045

The current CyberDefender.com footer separately displays 150 S. Los Robles Ave., Suite 400, Pasadena, CA 91101. Customers should not assume that this brand-site address is the same thing as RealDefense’s corporate headquarters or that either address should be used for returns, payments, cancellations, or refund requests.

How to Escalate a CyberDefender Complaint

1. Identify the current operator. Determine whether your issue involves CyberDefender, another RealDefense product, USTechSupport, or a third-party seller.
2. Use official support first. Contact RealDefense through the current support email, relevant product contact form, chat, or authorized support route.
3. Request a case number. Keep the reference number and date of the interaction.
4. Document billing issues. Save receipts, renewal notices, bank entries, and cancellation confirmations.
5. State the requested resolution. Be specific about whether you want cancellation, a refund, a billing correction, or technical assistance.
6. Follow up in writing. Refer to the earlier case number if the promised action does not occur.
7. Contact the payment company when appropriate. If an apparently unauthorized charge remains unresolved, ask your bank or card issuer about its dispute process before the applicable deadline expires.

CyberDefender Customer Service Frequently Asked Questions

What is the CyberDefender customer service phone number?

A current CyberDefender-specific general customer-service telephone number could not be confirmed. RealDefense’s terms state that standard support for its products is provided through USTechSupport. RealDefense separately publishes 1-801-857-2345 specifically for qualifying standalone-software refund requests.

Who owns or operates CyberDefender now?

RealDefense LLC’s current Terms of Service and Privacy Policy list CyberDefender software and CyberDefender.com within the RealDefense family of products and sites.

Is the old 1-866-793-0454 CyberDefender number still valid?

That older number could not be verified as a current CyberDefender or RealDefense customer-service number and should not be relied on for present-day support.

How do I cancel a CyberDefender subscription?

For a subscription handled by RealDefense, use the current support email, online chat, or product contact form and request cancellation of recurring billing. If a third party sold and billed the subscription, contact that seller directly.

Does uninstalling CyberDefender cancel billing?

Do not assume that uninstalling software cancels a subscription. Confirm cancellation separately and save written proof that recurring billing was stopped.

Can I get a CyberDefender refund?

RealDefense’s current terms state that qualifying standalone-software purchases may be refunded when the customer contacts RealDefense within 30 days of purchase. Other subscription fees are generally subject to different terms and may not be refundable.

Where is RealDefense headquartered?

Is the old CyberDefender Corporation still the operating company?

The old CyberDefender Corporation filed for Chapter 11 protection in 2012 in connection with an agreement to sell substantially all of its assets. Current CyberDefender materials instead connect the brand and website with RealDefense LLC.

How do I avoid a fake CyberDefender or RealDefense support call?

Navigate independently to the official CyberDefender, RealDefense, or authorized support website. Do not rely on a telephone number in an unsolicited pop-up, email, text, or cold call, and do not grant remote access until the support provider has been verified.

Can CustomerServiceNumbers.com access my CyberDefender account?

No. CustomerServiceNumbers.com is an independent consumer-information and review website. We cannot access CyberDefender or RealDefense accounts, cancel subscriptions, issue refunds, remove malware, repair computers, retrieve product keys, or provide remote technical support.

Why Trust CustomerServiceNumbers.com?

CustomerServiceNumbers.com has helped consumers locate customer-service information and share service experiences since 2004. We focus on separating current official support channels from outdated directories, unrelated technical-support companies, advertisements, and suspicious support contacts.

Cybersecurity brands, ownership structures, product names, subscription rules, support providers, telephone numbers, and websites can change. Always confirm important account, billing, refund, and technical-support information through current official sources before sharing sensitive information or granting remote computer access.
