Why each option
The workstation is redirecting the user to incorrect sites because it is infected with browser-hijacking malware, which is possible because it is disconnected from endpoint protection. Browser redirection malware alters DNS settings, the hosts file, or browser configuration to send users to attacker-controlled sites.
Browser redirection is a type of malware that modifies local browser settings, proxy configuration, or DNS entries to send users to unintended sites. The workstation being outside of endpoint protection allowed the infection to persist undetected. This explains why the behavior is isolated to one specific machine.
Pop-ups are intrusive advertisements or notifications but do not cause redirection to an entirely incorrect site for a specific service.
Ransomware encrypts files and demands payment; it does not redirect web browsing sessions to incorrect sites.
Spam refers to unsolicited bulk email messages and has no mechanism to redirect a user's browser to an incorrect site.
Hijacked email involves unauthorized access to an email account, not the redirection of a browser to a wrong website.
