Suspicious File Detected: A Guide to Understanding and Eliminating the Threat

The “Suspicious File Detected” notification is a misleading alert that often appears on the bottom-right corner of a Windows screen. Though it might look like a legitimate warning from trusted entities such as Microsoft Edge, Windows, or antivirus software (often McAfee), it is, in fact, tied to scams and malware. These deceptive messages are designed to lure users into revealing sensitive personal or financial information or to trick them into visiting malicious websites.

This threat can result in identity theft, data misuse, or malware infections, making it a severe issue that warrants immediate action. Recognizing the problem, understanding its implications, and removing the underlying malware or potentially unwanted program (PUP) are crucial steps for safeguarding your system.

What Is “Suspicious File Detected”?

The “Suspicious File Detected” pop-up is not a legitimate security alert. Instead, it is a scam notification triggered by browser hijackers, adware, or other potentially unwanted programs (PUPs). These notifications often attempt to mimic the design and language of authentic system alerts to gain users’ trust.

Characteristics of Suspicious File Detected Notifications:

• Frequent intrusive pop-ups that appear even when you are not browsing risky websites.
• Impersonation of legitimate companies like Windows or antivirus providers.
• Push notifications urging immediate action, often leading to phishing sites or malware downloads.

This pop-up is typically triggered by unwanted browser extensions, adware, or malware. The most common sources include:

1. Unreliable Software Downloads: Downloading files or programs from unverified sources can introduce adware and PUPs to your system.
2. Malicious Browser Add-ons: Extensions that claim to enhance browser functionality may carry malicious scripts that enable the pop-ups.
3. Redirects from Compromised Websites: Visiting unsecured or compromised websites may automatically load scripts that generate fake alerts.

Once installed or activated, the program behind the “Suspicious File Detected” notification can cause several issues:
