What can antivirus software protect computers from?

• A. It can prevent any malware from running regardless of detection.
• B. It can fix hardware faults.
• C. It can protect the computers from any malware that it is able to detect.
• D. It can clean any data after infection.

Answer: (C)

Antivirus software protects computers by actively detecting and blocking or removing malware it can recognize. It uses a database of known malware signatures and behavior-based checks to identify threats as they try to run, quarantining or deleting them to keep the system safe. The important point is that this protection only applies to malware the software can detect—new or unknown threats may slip by if they aren’t in its database or don’t trigger its detection methods. It doesn’t fix hardware faults, and while it can clean up malicious files during remediation, it can’t guarantee complete data cleanliness after every infection.
