CompTIA A+ 220-1102 Practice Question

The most likely cause of this issue is malware infection. Malware can modify the system to appear legitimate while simultaneously altering files and stealing user data. It can also cause sluggish performance by consuming system resources. While a faulty hard drive can cause slow performance and potential file corruption, it would be unusual for the hard drive to specifically affect the user's home directory. While a corrupted user profile can lead to slow performance and unexpected behavior, it is less likely to cause a major change to the desktop layout or file organization. System instability can cause slow performance, but is less likely to cause file and desktop alterations.
