How to Stop Robocalls, Spam Calls, and Phone Scams

Robocalls have earned the top spot on the FCC’s consumer complaint list year after year — and it’s easy to understand why. Americans receive billions of unwanted automated calls every month, and modern spoofing technology makes these calls appear to come from numbers you already trust: your doctor’s office, your bank, or even your next-door neighbor. The problem isn’t just annoying anymore — it’s a genuine financial and privacy threat. Understanding how robocall scams work is the foundation for stopping them. McAfee antivirus and privacy tools give you a powerful additional layer of defense on top of the practical steps covered below.

​

How Robocall Scams Work

Behind every robocall scam is a layer of deception designed to get you to lower your guard and either hand over information or authorize a payment. Spoofing is the core technique. Scammers use software that lets them display any phone number they choose on your caller ID screen, making it trivially easy to impersonate a bank, government agency, or familiar contact. The number you see is almost never the number actually calling you. Neighbor spoofing takes this further by programming the fake number to share your own area code and even your local exchange (the first six digits of your number). Studies show that people are significantly more likely to answer a call that appears local, making this technique especially effective. Perhaps most chillingly, voice cloning has made robocall scams capable of impersonating people you personally know. Researchers have found that as little as three seconds of recorded audio is enough to produce a voice clone with roughly 70% accuracy. With AI tools now widely accessible, scammers can harvest audio from social media videos and use it to make a fake “emergency call” from a family member’s voice. Common impersonation targets include the IRS, Social Security Administration, Medicare, major banks, and tech support departments — any authority figure that could create urgency or fear.

6 Ways to Beat Robocallers

You don’t have to be a passive target. These six steps significantly reduce both the volume of robocalls you receive and your vulnerability to the ones that still get through. 1. Don’t answer unknown numbers — and never say “yes.” Let unrecognized numbers go to voicemail. If you do accidentally answer, avoid saying “yes” as your first word. Scammers record your voice to authorize fraudulent charges or clone it for future scams. 2. Use your phone’s built-in spam filtering. Both major mobile platforms have native tools to help:

• iOS: Go to Settings → Phone → Silence Unknown Callers to send unrecognized numbers directly to voicemail.
• Android: Open the Phone app → Settings → Caller ID & Spam → enable “Filter spam calls.”

These are free, built-in, and require no extra apps. 3. Use your carrier’s call-blocking service. All four major US carriers offer free or low-cost call-blocking tools:

• AT&T: ActiveArmor (free app + network-level blocking)
• T-Mobile: Scam Shield (free, with a premium upgrade)
• Verizon: Call Filter (free tier available)
• US Cellular: Call Guardian (included)

Check your carrier’s website or app for enrollment options — most take less than two minutes to set up. 4. Register on the Do Not Call Registry. Visit donotcall.gov to add your number to the national Do Not Call Registry. While this won’t stop illegal scam operations (they ignore the list), it does reduce legitimate telemarketing calls and makes it easier for the FTC to take action when you report violations. 5. Don’t call back unknown numbers. If you miss a call from an unfamiliar number, resist the urge to call back. Some scam operations use “one-ring” tactics: they call once, you call back, and you’re connected to a premium-rate number that charges by the minute. If the call seemed important, search for the company’s official number independently and call that instead. 6. Use McAfee Personal Data Cleanup to remove your phone number from data broker sites. Robocallers don’t dial randomly — they buy lists. Your phone number, home address, and email are likely available for purchase on dozens of data broker websites right now. McAfee Personal Data Cleanup scans more than 30 of these sites, identifies where your information appears, and helps you get it removed. Fewer data brokers holding your number means fewer spam callers dialing it.

Be Careful with Call Blocker Apps

The app store is full of third-party call-blocking apps promising to silence robocallers forever. Some work well, but they come with a meaningful trade-off: to identify spam calls, these apps need access to your contact list, call logs, and sometimes microphone data. Before installing any call-blocking app, ask yourself:

• Does the app have a clear, readable privacy policy?
• Does it sell or share your contact data with third parties?
• Is it published by a company with a verifiable track record?

Some apps have been caught selling the very contact data they collected to the same brokers that fuel robocall lists — creating a self-defeating cycle. Stick to your carrier’s native tools or a reputable security suite rather than a free unknown app. Taking all six steps above — combined with choosing trustworthy tools over obscure free apps — gives you a serious edge over robocallers. No single measure is a silver bullet, but together they dramatically reduce both the volume of calls you receive and your risk when an unwanted call does get through.
