Windows Defender will now delete misleading disk cleanup programs

Add as a preferred source on Google

On Windows, there’s an ever-growing number of utilities designed for cleaning up your directories and thereby maximizing hard drive space. Some even intend on optimizing memory and processing speeds along the way.

While Microsoft doesn’t typically acknowledge these types of cleanup software, it is starting to call out some of the more deceptive tools disguised as cleaner/system-tuner resources. While being advertised as enhancements to your PC’s performance, the reality is that some of these programs are more likely to eat away at your computer speeds. Alternatively, some of these apps even charge money after revealing an extensive list of hindrances on your PC’s efficiency.

Now Microsoft is saying that any programs guilty of these crimes will be marked as “unwanted software,” meaning that — assuming you’re on Windows 10 — the company’s built-in Windows Defender will automatically remove them from your downloads. This is according to a post published on the Malware Protection Center blog, on which Microsoft clarifies that the aforementioned subset of these programs leaves its customers with “arbitrary and fear-based” purchasing decisions.

More specifically, it’s widely known that some of these programs detect a Windows system file variant, prefetch (.pf) files, as malware. In reality, though, these files are conceived by the operating system itself to reduce the load times of certain apps. Rather than improving on performance as advertised, these programs can actually be quite detrimental to your computer’s health.

The way this works for Windows Defender is remarkably straightforward. By developing an objective criteria for how malware programs “back up their claims, so that you have the ability to assess what the program found and deems to be errors,” users can determined if they would “like to take the program’s recommended actions.”

Essentially, this means that if the programs meddle with your system files, absent a necessary explanation for doing so, Defender will strike back with an equally terminal blow.

YouTube users in the U.S. are getting a new way to search for videos on the web. The company has started rolling out Ask YouTube, its conversational AI search experience, beyond the Premium-only test announced at Google I/O 2026.

Instead of entering a few keywords and scrolling through a standard list of results, users can ask YouTube a complete question. The feature is designed for broader searches where the exact video, channel, or topic may not already be clear.

Meta’s detection tool fails to identify photos generated by its own Muse Image AI
Meta has created an invisible watermarking tool called Content Seal that is embedded in all images generated by the Muse Image AI.
Meta AI identification tool.

Earlier this week, Meta announced two new AI products, namely, Muse Image and Muse Video. As the name suggests, these are generative AI tools for making photos and video clips using natural language text prompts. Soon after their rollout commenced, these tools sparked controversy because Meta had automatically opted in Instagram users, allowing others to use their publicly posted media and convert them into remixed AI content. But it appears that Meta courted another loss on its side of the court.

Your Google AI Studio apps can finally have polished, presentable web links
AI Studio web apps can now use personalized subdomains

Google AI Studio has made building a web app surprisingly easy. You can describe what you want, refine the design through prompts, and publish the result without setting up a traditional development environment. An awkward point of friction comes after deployment, when the finished app still has to live behind a long, forgettable Cloud Run link.

Google is now cleaning up that final step. AI Studio lets you assign a deployed web app a personalized address under the “ai.studio” domain, such as “your-app-name.ai.studio.” A recognizable URL should make the project look more presentable in a portfolio, client demo, social post, or internal project page.
