Fake Claude AI Website Found Spreading Harmful Software

Scammers have created a fake Claude AI website (claude-pro[.]com) that looks almost identical to the real one (claude[.]ai). If you visit it and download any files, it can secretly install harmful software on your computer.


Who Is at Risk

Anyone searching online for Claude AI or other AI tools, especially Windows users who click download buttons from ads, search results, or websites they do not recognize.

What to Watch For

Look closely before downloading anything. Be suspicious if the website offers a “Claude-Pro Relay” download, tells you to install a file before you can use Claude, or has a web address that does not match the official Claude site.

What to Do

Only use the official Claude website and avoid downloading software from unfamiliar links.
