Free CompTIA A+ 220-1102 Practice Question

The correct action to take is to perform a complete scan with an updated anti-malware software. The described symptoms are indicative of potential rogue security software, also known as 'scareware,' which can masquerade as legitimate security alerts to convince users to purchase a fake antivirus program. Performing a thorough scan will help identify and remove any malicious software that the current antivirus might have missed. Updating the anti-malware software is essential to recognize the newest threats. Restoring the system could potentially remove the malware but might not be effective if the malware is designed to evade such measures. Similarly, utilizing a safe mode and preinstallation environment for scanning should be done if the full scan in the normal mode is not possible or effective, but as a first response, updating and scanning the system is recommended. Lastly, the suggestion to disable antivirus software is incorrect because it could exacerbate the security concerns by leaving the system vulnerable.
