A server administrator decides to install anti-malware software to prevent outside attacks. Which of the following threats are being prevented?

Anti-malware software, including antivirus programs, specifically targets and prevents the execution and spread of malicious software like viruses, worms, and trojans by scanning files and monitoring system behavior for known malicious patterns. This software protects the server from internal infection and potential data corruption or exfiltration caused by such programs.

IPSec is a suite of protocols used for securing IP communications by authenticating and encrypting each IP packet, not a threat prevented by anti-malware.

DDoS (Distributed Denial of Service) attacks overwhelm a system with traffic to make it unavailable and are typically mitigated by network perimeter defenses, not anti-malware software.

Network flooding is a type of denial-of-service attack that overloads network resources with excessive traffic, which is prevented by firewalls and intrusion prevention systems, not anti-malware software.
