Answer Key

Software malware updates

Section A: Quick Questions

B — True

A — Updating daily

B — True

A — Automatic updates

A — False

Section B: Match the Pairs

if defs_ver != latest: update_defs() → Checking if definitions are outdated and updating them

skip_defs_update = True → Disabling definition updates, leaving detection outdated

Updated definitions let security software detect new threats → update_defs(latest_defs)

Scanning after an update checks the system against current definitions → scan_for_malware()

ignore_new_threats = True → The mistake: ignoring threats detected by updated definitions

revert_to_old_defs() → The mistake: reverting to outdated definitions after updating

Section C: Definitions

Malware definition update — Refreshing the database used by security software so it can recognise and detect newly discovered threats.

Section D: Fill in the Blanks

malware_defs = get_latest_defs()

update_enabled = True

if defsVer != latestVer:

def scan_for_malware():

quarantine_enabled = True

Section E: Spot the Error

A — Line 1 skips updating malware definitions, so new threats won't be detected.

B — Line 2 disables future definition updates, leaving detection outdated over time.

C — Line 3 does nothing when definitions are outdated, instead of triggering an update.

D — Line 4 resets the definitions back to an old version after applying the update.

E — Line 5 ignores newly detected threats instead of quarantining them.
