Why each option
Pop-ups appearing both in the browser and as OS-level notifications outside the browser indicate adware or malware installed on the system, requiring an anti-malware tool to detect and remove.
A firewall controls inbound and outbound network traffic but cannot detect or remove malware that is already installed and actively running on the local system.
OS security updates patch known vulnerabilities to prevent future exploitation but do not actively scan for or remove malware that has already been installed.
Chkdsk is a file system integrity tool that checks for disk errors and has no capability to detect or remove malware or adware processes.
An anti-malware application is specifically designed to scan, detect, and remove malicious software including adware that generates unsolicited pop-ups. Notifications appearing outside the browser indicate a persistent process or browser extension installed at the OS level, which only a dedicated malware scanner can fully identify and remediate.
