What is fake DeepSeek AI Chat extension?

This extension misleadingly claims to be affiliated with DeepSeek AI, a well-known and reputable service, in an attempt to appear legitimate and trustworthy. It is designed to collect user-inputted data and transmit it to its developers. This creates a privacy concern, as malicious third parties could access sensitive information through the fake extension.

Fake DeepSeek AI Chat extension overview

The fake DeepSeek AI Chat extension collects data from users, including their chat history, IP addresses, and any information they enter, and sends it to a server (ai-chat-bot.pro) controlled by its developers. Over time, the continuous data leak could lead to identity theft, phishing attacks, targeted scams, and other issues.

Also, the extension includes a rating widget that manipulates feedback. Users who give low ratings are redirected to a private feedback form, while those who give high ratings are sent to the official Chrome Web Store review page. This practice boosts the extension's public rating, violating Chrome Web Store policies.

Moreover, it includes a script that directs users to a shady welcome page and tracks install/uninstall events. The page also sets tracking cookies and gathers browser information without permission. Overall, the fake DeepSeek AI extension should be removed from web browsers as soon as possible (if it has been added) to avoid the associated risks.

How did unwanted applications install on my computer?

Sometimes, fake extensions are disguised as useful tools in official stores like the Chrome Web Store, but with misleading descriptions and names to trick users into adding them to their browsers. Unofficial web pages are also commonly used to distribute fake or unreliable extensions and apps.

Also, these extensions can be packaged with free or suspicious software that users download. If users install programs without changing the provided options ("Advanced" or "Custom") that mention unwanted apps, they accept additional offers. In other cases, users may get unwanted apps via deceptive ads, pop-ups, P2P networks, third-party downloaders, and similar sources.

How to avoid installation of unwanted applications?

Always download software from reliable sources, such as official websites or app stores. During installation, opt for the "Custom" or "Advanced" settings to review and reject any unnecessary offers. Ensure your programs and operating system are regularly updated, and protect your system with a trusted security tool.

Also, avoid accepting notifications from untrustworthy websites and be cautious of pop-ups, links, and fake download buttons on suspicious sites. If your computer is already infected with rogue apps, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
