CompTIA A+ Core 2 (220-1002) — Question 8

A technician is working on a user's workstation and notices a lot of unknown processes running in the background. The user informs the technician that an application was recently downloaded from the Internet.
Which of the following types of infection does the user MOST likely have?

Answer options

• A. Rootkit
• B. Keylogger
• C. Trojan
• D. Ransomware

Correct answer: C

Explanation

The user is likely dealing with a Trojan, as these are often disguised as legitimate applications but can introduce harmful processes once downloaded. Rootkits and keyloggers have different characteristics and purposes, while ransomware typically involves encrypting files for ransom, which is not indicated in this scenario.
