A user is experiencing persistent pop-up warnings that spoof Windows Defender and McAfee, indicating potential malware infection. Despite blocking pop-ups and running antivirus scans, the user continues to receive these alerts, suggesting the presence of adware or phishing attempts. Recommendations include utilizing Windows' Restore Point feature to revert to a previous system state, and employing tools like Process Explorer to identify suspicious processes. The user has attempted to clear temporary files and adjust browser settings, which have reduced the frequency of pop-ups but not eliminated them entirely. There is a discussion about the effectiveness of various antivirus programs and the possibility of zero-day vulnerabilities in Microsoft Edge. The user is advised to remain cautious and consider using a VPN for secure browsing, especially when on public Wi-Fi.
