    FAQs

    How common are online scams today?

    Online scams are on the rise. In late 2024, social engineering threats made up nearly 90% of all cyberattacks, according to a recent Gen Threat Report. And cybercrime victims reported a record total of $16.6 billion in losses to the FBI in 2024, according to the Internet Crime Complaint Center (IC3).

    Cybercriminals are leveraging sophisticated AI to craft more convincing schemes, targeting both individuals and businesses. This growing threat underscores the urgent need for heightened digital awareness and stronger security practices.

    How do I know if a website or message is a scam?

    It’s increasingly difficult to spot a scam website or identify a fake message just by looking for poor grammar, urgent language, unfamiliar senders, and suspicious links. That’s why you should use an AI-powered scam detection tool like Avast Assistant to review suspicious content and help you decide what’s safe and what’s best avoided.

    Is scam protection included in the free version of Avast’s antivirus?

    Yes, Avast Free Antivirus includes built-in scam protection for Windows and Mac. This free cybersecurity software package uses AI to help automatically detect suspicious websites and phishing attempts in real time. It also lets you interact with an AI assistant for quick guidance on shady messages.

    What should I do if I get scammed online?

    If you get scammed online, act fast to protect yourself and others from further harm: change your passwords, alert your bank, and report the scam to the relevant authorities. You should also preserve evidence, like emails or screenshots, to help you report cases of identity theft if you fall victim.

    How can I tell if a phone number is from a scammer?

    Scam phone numbers are notoriously difficult to detect, because scammers often use spoofed phone numbers to impersonate trusted contacts or institutions. Avast’s scam detection tool can help by analyzing related messages and giving you instant advice through its built-in AI Assistant, so you stay protected.

    Is it safe to rely on free security software for online protection?

    Trusted free security software like Avast Free Antivirus offers strong core protection against scams, phishing, and malware. It includes real-time threat detection and an AI assistant to help you navigate the digital world safely. While some paid tools like Avast Premium Security offer even more features — such as automatic protection for more channels — dependable free apps offer a safe and effective first line of defense.

    How do I protect my personal information from online scams?

    To keep your personal info safe from online scams, use strong passwords and turn on two-factor authentication. Be careful with unexpected messages or links, and don’t share details unless you’re certain of the recipient's identity. Keep your software updated and stick to trusted websites and security tools.
