Real-time protection by Guard in Secura Web Total Security Antivirus is a crucial feature designed to actively monitor and safeguard users' systems against a wide range of security threats in real-time. It works continuously in the background, proactively identifying and blocking malicious activities, files, and processes before they can cause harm to the system. Here's a detailed explanation of the Real-time protection by Guard feature and its key aspects:

1. **Continuous Monitoring**: Real-time protection by Guard operates continuously, monitoring various entry points and activities on the user's system in real-time. This includes monitoring file system
   activities, network traffic, system processes, memory operations, and other critical areas susceptible to security threats.
2. **Malware Detection**: The primary function of real-time protection is to detect and block malware in real-time. This includes viruses, trojans, worms, ransomware, spyware, adware, and other types of malicious software. The antivirus software uses advanced detection techniques such as signature-based scanning, heuristic analysis, behavior monitoring, and machine learning algorithms to identify and quarantine malicious files and processes as soon as they are detected.
3. **Zero-day Threat Prevention**: Real-time protection by Guard is capable of detecting and blocking zero-day threats - previously unknown malware that exploits newly discovered vulnerabilities or bypasses traditional signature-based detection methods. By analyzing file behavior, reputation, and other indicators of compromise in real-time, the antivirus software can proactively identify and mitigate emerging threats before they can cause widespread damage.
4. **Web Protection**: Real-time protection extends to web browsing activities, preventing users from accessing malicious websites, phishing scams, and other online threats in real-time. The antivirus
   software may use URL filtering, reputation-based analysis, and other techniques to block access to malicious or suspicious websites and prevent users from inadvertently downloading malware or falling
   victim to online scams.
5. **Email Protection**: Guard may also provide real-time protection for email communications, scanning incoming and outgoing email messages and attachments for malware, phishing attempts, and
   other email-based threats. By integrating with popular email clients or servers, the antivirus software can intercept and block malicious email content before it reaches the user's inbox, thereby protecting against
   email-borne threats.
6. **Automatic Threat Remediation**: When a threat is detected in real-time, Guard takes immediate action to mitigate the threat and prevent it from causing harm to the system. This may involve
   quarantining infected files, terminating malicious processes, blocking network connections, or alerting the user about the detected threat. Automatic threat remediation helps minimize the impact of security
   incidents and ensures that users' systems remain protected at all times.
7. **Low System Resource Usage**: Real-time protection by Guard is designed to operate efficiently with minimal impact on system performance. The antivirus software uses optimized scanning algorithms,
   intelligent resource management, and background scanning techniques to ensure that real-time protection does not slow down the system or interfere with other activities.

Overall, real-time protection by Guard in Secura Web Total Security Antivirus provides users with proactive, continuous protection against a wide range of security threats, helping to keep their systems
safe and secure in today's constantly evolving threat landscape. By leveraging advanced detection techniques, real-time monitoring, and automatic threat remediation, Guard offers comprehensive defense
against malware, phishing, and other online threats in real-time.
