Software TroubleshootingCâu 64 / 100
A user's files suddenly have a strange extension and a note demands payment to restore them. What has most likely happened, and what is the safest recovery path?
a.A driver conflict; update the driver
b.A failed update; reinstall the update
c.A dead battery; replace it
d.A ransomware infection; isolate the system and restore data from clean backups
Giải thích
Renamed files plus a ransom note indicate ransomware. The safest recovery is to isolate the machine and restore from known-clean backups rather than pay. Driver or battery explanations do not match these symptoms.
