CompTIA A+ 220-1102 Practice Question

Rootkit removal tool - This is correct. Rootkits are designed to hide themselves deep within the operating system, often bypassing standard security measures. Specialized rootkit removal tools are specifically designed to detect and eliminate rootkits. These tools use advanced techniques to uncover hidden files, processes, and registry entries associated with rootkits.

Standard antivirus software - While standard antivirus software can detect and remove many types of malware, it often struggles to detect rootkits due to their ability to operate stealthily and deeply within the system.

Disk defragmentation tool - A disk defragmentation tool is used to reorganize fragmented files on a hard drive for performance optimization. It is not designed to detect or remove malware.

System restore utility - System Restore can revert the system to a previous state, potentially bypassing some malware. However, rootkits can often embed themselves in critical system areas that System Restore does not fully clean, making this method unreliable for rootkit removal.
