Dealing with Persistent Microsoft Defender Subscription Scam Pop-ups: A How-To Guide

In today’s digital landscape, encountering Software scams can be a frustrating and, at times, alarming experience. Recently, a user faced an annoying issue with a persistent Microsoft Defender subscription scam pop-up that kept resurfacing on their computer. Let’s explore this concern and discuss effective methods for addressing it.

Understanding the Scam

Our user reported a pop-up message claiming, “Your Windows Defender antivirus is upgraded to a Pro plan of $299.00, and the payment will be charged from your credit card on August 26, 2024.” Recognizing such notifications as scams is crucial, especially when they attempt to extract sensitive financial information or coerce users into purchasing unnecessary services.

The Insistent Pop-Up Problem

Despite the user’s efforts to eliminate the pop-up—such as deleting all browser data and attempting to run Microsoft Defender scans (quick, full, and offline)—the issue persisted, with the pop-up continuing to activate PowerShell. This raises concerns about the possibility of deeper issues within the system.

Investigating Potential Compromises

One particular element that caught our user’s attention was the appearance of conhost.exe in the System32 directory. Although many sources confirm that this file is typically not harmful, the fact that it triggers PowerShell every time the scam pop-up appears warrants further investigation.

Steps to Resolve the Issue

If you find yourself in a similar situation, here are several steps you can take to mitigate the problem:

Run a Comprehensive Anti-malware Scan: While Microsoft Defender has been utilized, consider supplementing it with reputable anti-malware Software for a broader search. Tools like Malwarebytes can often identify threats that conventional scanners might miss.
Check for Unwanted Programs: Go through your installed programs in the Control Panel. Uninstall any unfamiliar or recently added Software that could be linked to the scam.
Review Task Manager: Open Task Manager and inspect the processes running on your machine. Pay special attention to any suspicious activities. If you see conhost.exe consistently launching under PowerShell, it may require deeper analysis.
Clear Browser Data Again: Make sure to clear caches, cookies, and browser history again, especially if you’ve installed new tools or extensions that may contain vulnerabilities.
Reset Your Browsers: Consider resetting your browsers to default settings, which can eliminate any mal
