Avast is making a broader push against scams, and the timing makes sense. Scam Guardian and Scam Guardian Pro are now available internationally on mobile devices, and the company is also launching a new Windows feature called Deepfake Guard. Together, the updates are aimed at a problem that has quietly gotten harder to spot, scams that look and sound real enough to blend into everyday browsing.
Deepfake Guard focuses on manipulated audio inside video content, which is where a lot of newer scams are showing up. Instead of chasing suspicious downloads or sketchy links, it listens to the audio in videos you are already watching and looks for signs that something has been altered. The analysis happens directly on the PC, which keeps things faster and avoids sending video data elsewhere. Avast says the feature is designed to work on regular Windows PCs, while also taking advantage of newer AI-focused hardware when it is available.
What stands out is how normal these scams are starting to look. Gen Threat Labs data shows that in the fourth quarter of 2025 alone, more than 159,000 unique deepfake scams were detected on devices where real-time video analysis was active. Platforms like YouTube, Facebook, and X accounted for much of that activity. In many cases, the scam content appeared as part of normal viewing rather than something users actively clicked on or downloaded. That makes the problem harder, because there is often no obvious moment where alarm bells go off.
This is where Avast is clearly trying to reposition scam protection. The argument is that fake voices and manipulated videos are not dangerous on their own. The real risk comes when they are used to create urgency, apply pressure, and exploit trust. A convincing voice telling you to act now can short-circuit common sense faster than a badly written email ever could. Deepfake Guard is meant to interrupt that moment and raise a flag before someone reacts.
On phones, the global expansion of Scam Guardian brings more consistent coverage for scam calls, texts, and emails. The idea is that protection should follow people across devices. Someone might ignore a suspicious text in the morning and then encounter a slick-looking video later that day. Avast wants both situations covered, without requiring users to think too much about which screen they are using.
There are practical limits. Deepfake Guard is opt-in, and how it works depends on the hardware. Lower-specification PCs can install it manually, but automated detection is not recommended because of potential performance impact. Higher-end Windows 11 systems can enable automated detection, and AI-focused PCs get the smoothest experience by default. At launch, video analysis supports English-language content across major platforms, and the feature is included with Avast Premium Security.
Deepfakes are not going away, and no software is going to magically solve that. What this update does show is how security tools are shifting to match reality. Scams in 2026 are often polished, familiar, and easy to miss. Protection that quietly questions what you are seeing or hearing, without getting in the way, may end up being more useful than another warning about suspicious links.
