Why each option
Viruses commonly manifest as sudden drops in system performance and corrupted or deleted files, while display issues and faster drive access are not characteristic virus symptoms.
Viruses consume CPU cycles, memory, and disk I/O as they replicate and execute malicious payloads, which directly causes a noticeable reduction in available system resources and overall system slowdown.
Many viruses overwrite, encrypt, or delete files as part of their payload delivery, resulting in corrupted, inaccessible, or missing files - a classic and well-documented symptom of infection.
An unclear or distorted monitor display is typically caused by hardware failure, a faulty GPU, bad display drivers, or physical cable issues - not by virus activity.
Viruses do not increase the read/write speed of optical drives; faster CD-ROM access is a hardware characteristic unaffected by malware.
