Mobile scams are evolving — your protection should too
In 2024, scams cost victims more than $1 trillion worldwide — most carried out through phone calls and text messages. And the reason for this cybercrime epidemic is clear: scammers now use AI-generated assets, spoofed caller IDs, and highly convincing language to trick victims into sharing personal information, sending money, or clicking malicious links.
That’s why the Avast Premium Security mobile app now includes Scam Guardian Pro — our most advanced, always-on scam protection. Powered by AI, it helps identify and block dangerous messages, calls, and emails, so you can connect with confidence and avoid costly traps.
Why scams are trickier than ever
Scammers aren’t just sending clumsy, typo‑filled messages anymore. They’re using AI to write flawless copy, spoof legitimate phone numbers, and mimic the tone of trusted companies. The result? Sophisticated social engineering ploys that can fool even the most cautious person.
We’ve all been on the receiving end:
-
Delivery texts claiming your package is delayed — just click this link.
-
Calls “from your bank” demanding your account details right now.
-
Emails warning you to reset your password before it’s “too late.”
These scams exploit urgency and trust to push you into acting before you think. But Scam Guardian Pro flips the script, blocking threats before they can fool you, so you never have to make a split-second, risky decision.
One app. Four smart protections.
Scam Guardian Pro brings together four powerful AI-driven scam detection tools in one simple dashboard inside Avast Premium Security:
-
SMS Guard – AI-powered scam detection for every text message.
-
Call Guard – Instantly identify which calls are safe to answer.
-
Email Guard – Proactively flags suspicious emails in your inbox.
-
Avast Assistant – Real-time interactive scam protection.
No juggling multiple apps. No second-guessing your safety. Just complete, reliable scam protection you can count on.
SMS Guard
Scam texts can be used to steal your money, data, and peace of mind in seconds. SMS Guard stops them cold. Using Avast’s AI engine, it scans every message in real time, detecting scam patterns and malicious links — even brand-new ones. If something looks suspicious, SMS Guard flags or blocks it before it lands in your inbox.

Why you’ll love it:
-
Identifies scam texts automatically
-
Adapts instantly to new scam tactics
-
Protects you from malicious links
-
Works silently in the background
Example: You’re waiting for a delivery, and a text claims you must “confirm payment” to receive it. SMS Guard intercepts and blocks it before you even think about tapping.
Call Guard
Scam calls are more than a nuisance — they can be costly. Call Guard makes it easy to know which calls to trust by using smart AI to filter malicious calls. The names of verified business numbers are displayed, known scams are blocked outright, and suspicious calls are flagged so you can decide whether to pick up.

Why you’ll love it:
-
Blocks scam and spam calls automatically
-
Warns you about risky numbers
-
Labels businesses for easy recognition
-
Helps you answer with confidence
Example: Call Guard flashes “Scam Caller” on your screen before you answer — so you hang up right away, instead of exposing yourself to a fraudster claiming to be from your bank.
Email Guard
Email is still a top choice for scammers, which is why we’ve built Email Guard to help keep them out of your inbox. It connects to major email providers in just a few clicks. Then, it scans messages in the cloud, detecting phishing attempts, deceptive content, malicious attachments, and spoofed senders before they reach you.

Why you’ll love it:
-
Detects scams automatically
-
Flags dangerous emails
-
Works on all your devices
-
Keeps your inbox worry-free
Example: A scam email looks like a friendly message from someone you trust, but Email Guard flags it before you even open it, so you don’t get caught off guard.
Avast Assistant
Sometimes you just want to ask: “Is this real?” Avast Assistant gives you the answer. Snap a screenshot, upload a suspicious ad, or paste a questionable link. The interactive Avast Assistant instantly analyzes it, explains the risks in plain language, and tells you exactly what to do next.

Why you’ll love it:
-
Instant answers about suspicious content
-
Works with text, images, and links
-
Explains threats in simple terms
-
Offers help with your Avast protection
Example: You spot an unbelievable online deal for a designer watch. Upload the ad to Avast Assistant, and seconds later, it confirms it’s a scam and tells you why.

Can Scam Guardian Pro block a legitimate message or call?
It’s rare, but possible, if a legitimate message or call shares traits with known scams. If this happens, you can easily review your call logs and restore messages from within the app. This gives you full control over what’s allowed through while still protecting you from genuine threats.
Will Scam Guardian Pro slow down my phone or drain my battery?
No, Scam Guardian Pro is designed to run efficiently in the background, using lightweight processes that have minimal impact on performance and battery life. You’ll stay protected without noticing any slowdown.

No, with just one multi-device Avast Premium Security subscription, you can install the Avast Mobile Security app on Android and iOS devices. Whether you switch phones or use multiple devices, you can enjoy seamless protection from Scam Guardian Pro without needing separate accounts or purchases.
Is it better than my phone’s built-in spam filter?
Yes. While built‑in spam filters block some unwanted messages or calls, Scam Guardian Pro uses AI‑driven protection that goes beyond simple keyword matching. It monitors texts, calls, emails, and suspicious online content in real time to detect sophisticated scams, phishing attempts, and fraud tactics that default filters often miss.
