Cevap

The technician should remove the unauthorized browser extension and reset browser settings, as well as inspect and clean unauthorized IP mappings from the local Windows hosts file.
Resolving browser hijacks and unauthorized pop-ups requires tackling both application-level components (removing malicious extensions and resetting configuration defaults) and OS-level redirection vectors (clearing unauthorized entries in the local hosts file).

Adım Adım Çözüm

1
Identify browser hijack vectors
Discovered rogue extension and persistent browser redirects.
Unauthorized browser extensions can override homepages, search engines, and security settings.
2
Remove malicious browser add-ons and reset configuration
Restored original browser behavior and blocked pop-up scripts.
Resetting browser settings to default removes policy overrides and disables untrusted extensions.
3
Check system-level redirection mechanisms
Identified and removed malicious static entries in C:\Windows\System32\drivers\etc\hosts.
Host file entries override DNS resolution and cause domain redirects independent of browser settings.
