a.The keyboard is failing
b.The system is infected with malware
c.The monitor cable is loose
d.The BIOS date is wrong
Giải thích
Pop-ups without a browser and a disabled antivirus strongly indicate a malware infection actively defending itself. Hardware or BIOS issues would not disable security software or generate advertising pop-ups.
