1.) Identify at least two features that you think would be most useful. Why do you think these are useful?

2.) There is an option to exclude specific files, folders, file types, or processes from being scanned. This is an option that can be used for trusted items that you are certain don’t need to be scanned. What would be the pros and cons of setting this option?

3.) There was an option to check for Protection Updates in the previous activity. Why might it be a good idea to check for protection and antivirus updates?

1) Two useful features could be real-time scanning and automatic updates.

Real-time scanning continuously monitors the system for any malicious activities or files. It instantly detects and blocks any threats, providing immediate protection. This feature is useful as it prevents malware from infecting the device and causing damage.

Automatic updates ensure that the antivirus software's database is up to date with the latest definitions and security patches. It helps improve the effectiveness of the antivirus program by detecting and defending against newer threats. This feature saves time and effort for the user, as they don't have to manually update the software and can trust that they are protected against the latest threats.

2) Setting the option to exclude specific files, folders, file types, or processes from being scanned can have both pros and cons.

Pros:
- Improved system performance: Excluding trusted files or processes from scanning can reduce the workload of the antivirus software, leading to better system performance.
- Avoiding false positives: Sometimes, antivirus programs mistakenly identify legitimate files or processes as threats. By excluding trusted items, users can prevent unnecessary alarms or actions taken against harmless files.
- Time-saving: Excluding trusted items from scanning can save time, especially for large files or folders that don't pose a high risk of infection.

Cons:
- Increased risk: Excluding certain files or processes from scanning means they will not be checked for malware, making the system more vulnerable to potential threats.
- Overlooking malware hiding in trusted items: Certain types of malware can hide within seemingly trusted files or processes. By excluding them, users may inadvertently leave their system exposed to potential malicious attacks.
- Difficult to determine trusted items: It can be challenging for users to accurately identify which files or processes are truly safe and don't need to be scanned. Mistakes in excluding critical items can result in compromised security.

3) Checking for protection and antivirus updates is crucial for maintaining a high level of security. Updating the antivirus software's protection and database definitions ensures that it has the latest information regarding new malware threats, vulnerabilities, and methods of attack. This helps the antivirus program in accurately detecting and blocking potential threats.

Regularly updating the antivirus software is essential because:
- New threats are constantly emerging, and updating protection updates the software's defense mechanisms against the latest malware.
- Vulnerabilities in the software itself can be patched, preventing attackers from exploiting them.
- Outdated antivirus software may not effectively detect or combat newer types of malware, leaving the system at risk.
- Security updates may add additional features or enhancements to the software, improving overall protection.

By checking for updates, users can ensure that their antivirus software is armed with the latest tools and information to guard against potential threats and maintain a secure system.

Is the history function of CodeHS more similar to a full backup or an incremental backup? Explain your answer.

The history function of CodeHS is more similar to an incremental backup rather than a full backup.

In backup systems, a full backup refers to creating a complete duplicate copy of all the files and data at a specific point in time. On the other hand, an incremental backup only backs up the files that have changed since the last backup.

The history function in CodeHS allows users to view previous versions or iterations of their code. It maintains a record of changes made to the code over time, including additions, deletions, and modifications. When a user accesses the history, they can see a timeline of different versions of their code, with the ability to compare and revert to previous versions if needed.

This functionality aligns more with an incremental backup because it captures and stores only the changes made to the code rather than duplicating the entire codebase. Each time the code is saved or modified, the system records the specific changes, making it more efficient in terms of storage and retrieval compared to maintaining a full backup of the codebase every time.

1.) Two useful features in a software/application could be:

a) Real-time scanning: This feature constantly monitors files and activities on a computer to detect and block any potential threats or malware in real-time. Real-time scanning provides proactive protection and prevents malicious files from executing or causing harm to the system. It is useful because it helps ensure the security and integrity of the computer and its data by immediately identifying and stopping any ongoing threats.

b) Scheduled scans: This feature allows the user to set up automatic scans at specific times or intervals. Scheduled scans are useful because they ensure regular and thorough scanning of the system, even when the user might forget or neglect to initiate a manual scan. This helps in detecting any malware or security vulnerabilities that might have been missed otherwise.

2.) Pros of excluding specific files, folders, file types, or processes from being scanned:

- Improved scan efficiency: Excluding trusted items that do not require scanning will reduce the overall scanning time and resource usage of the antivirus software, leading to quicker scans.
- Avoiding false positives: Some legitimate files or processes might trigger false positives and be flagged as potentially harmful by the antivirus software. Excluding such items can prevent unnecessary alerts or quarantines.

Cons of excluding specific items:

- Increased risk: By excluding certain files or processes from scanning, there is a possibility of inadvertently ignoring potential threats. If any of the excluded items get infected, the antivirus software will not detect it.
- Malicious file disguise: Malware can be designed to camouflage itself within trusted files or folders. Excluding such items from scans might allow the malware to go undetected.

To make an informed decision, it is recommended to only exclude items that are from trusted sources and that have been thoroughly assessed for security risks.

3.) It is a good idea to check for protection and antivirus updates because:

- New threats: Protection updates include new threat definitions and patterns, which enable the antivirus software to recognize and block the latest malware and viruses. By regularly updating, the system stays protected against emerging threats.
- Vulnerability fixes: Updates often include security patches that fix vulnerabilities or loopholes in the antivirus software itself. By keeping the software up to date, the chances of attackers exploiting such vulnerabilities are reduced.
- Performance improvements: Updates may also include performance enhancements that can optimize the antivirus software's scanning speed, resource utilization, and overall efficiency.
- Compatibility: Updates ensure that the antivirus software remains compatible with the latest operating systems or platforms, avoiding any issues or conflicts that might arise due to outdated software.

Regularly checking for protection and antivirus updates helps ensure the antivirus software's effectiveness, enhances system security, and keeps pace with the ever-evolving threat landscape.
