What software program prevents, detects, and eliminates malware from a system?

• A. Anti-Virus Software
• B. Adware
• C. AES
• D. AdHoc

Answer: (A)

Antivirus software prevents, detects, and eliminates malware on a system. It runs in the background, compares files and processes against a database of known malware signatures, and uses behavioral analysis to spot suspicious activity. When it finds a threat, it can quarantine or remove it and update its definitions to protect against new malware. This type of program also often offers real-time protection, scheduled scans, and alerts to keep the system safer over time.

Adware isn’t protective software; it’s software that displays ads and can be intrusive or track user behavior. AES is an encryption standard used to protect data, not to detect or remove malware. AdHoc refers to a temporary, improvised setup or network and isn’t a protection tool.
