CompTIA A+ Core 2 (220-1002) — Question 328

A technician is alerted to a virus on a PC. The technician isolates the PC from the network. After verifying there are no other infected PCs on the network, which of the following is the SAFEST method for the technician to use to clean the infected PC?

Answer options

• A. Download and apply the security patch that addresses the vulnerability that was exploited
• B. Use System Restore to bring the PC back to a previous restore point
• C. Reimage the computer and update it with all the latest patches
• D. Download another antivirus software that will quarantine the virus

Correct answer: C

Explanation

Reimaging the computer and updating it with the latest patches ensures a clean slate, free from any malware remnants, making it the safest option. Downloading a security patch or using System Restore may not fully eliminate the threat, and relying on another antivirus software could miss potential risks or fail to completely remove the virus.
