A student computer user downloads and installs an antivirus software program. The user manually runs the software regularly, but opts to update only manually and infrequently. This situation is most likely to result in which of the following outcomes?
  1. Only files modified since the last update will be scanned.
  2. The software may not identify files infected with newer virus signatures.
  3. Data files scanned previously will not be scanned again.
  4. The software may not be able to quarantine the infected files it finds.
Explanation
Correct Response: B. Antivirus software must be updated frequently because new viruses appear on a regular basis. Without the latest updates, the antivirus software cannot detect the latest viruses. A, C, and D are incorrect because updates have no effect on which files will be scanned (A and C), or on the quarantining of infected files (D).
