Final answer:
Anti-malware can prevent, detect, and remove software threats.
Step-by-step explanation:
Anti-malware can prevent, detect, and remove software threats such as ransomware, Trojans, spyware, and rootkits. It is specifically designed to identify and mitigate various types of malware. Unlike firewalls and VPNs, which primarily focus on network security, anti-malware is specifically tailored to combat malicious software threats. The tool that can prevent, detect, and remove software threats including ransomware, Trojans, spyware, and rootkits is anti-malware software. Anti-malware programs are specifically designed to combat a wide range of malicious software (malware) by using a combination of signature-based detection, heuristic analysis, and behavioral monitoring. This kind of software often includes real-time protection, automatic updates, and sometimes even a quarantine option to isolate potential threats. Other options mentioned, such as firewalls, VPNs, and registry cleaners, serve different security and maintenance roles. A firewall is meant to control incoming and outgoing network traffic and prevent unauthorized access, while a VPN secures internet connection and privacy. A registry cleaner, on the other hand, is used to remove obsolete or unwanted items from the Windows registry, but does not protect against malware.
