Comprehensive and Detailed In-Depth Explanation:Ransomware is a type of malware that encrypts files and demands payment (usually in cryptocurrency) to decrypt them.

B. Keylogger – Tracks keystrokes but does not demand payment.

When a user reports slow performance, a changed home page, and pop-up ads, these are classic signs of malware infection. The first step should be:

Update the antivirus program and run a full system scan: This helps identify and remove any malware present on the system, addressing the root cause of the issues.

Uninstall the suspicious search engine and reset the home page: This addresses the symptom but not the underlying cause, which is likely malware.

Install the latest updates for the operating system: Important for security but secondary to removing malware.

Block the pop-up ads using the web browser settings: Again, addresses the symptom but not the root cause.

For managing permissions where a specific folder needs to have different access controls than its parent, turning off inheritance for that specific folder is the correct approach.

Option A: Turn off inheritance on the requested folder only and set the requested permissions to each file manuallyThis is partially correct, but setting permissions manually for each file is inefficient and error-prone.

Option B: Turn off inheritance at the top-level folder and remove all inherited permissionsThis action would disrupt permissions for all other folders and files, not just the confidential folder.

Option C: Turn off inheritance at the top-level folder and set permissions to each file and subfolder manuallyThis approach is overly broad and inefficient, impacting more than just the specific folder that needs restricted access.

Option D: Turn off inheritance on the requested folder only, set the requested permissions, and then turn on inheritance under the child foldersThis ensures the specific folder has unique permissions while allowing those permissions to propagate to its children, maintaining security and ease of management.
