Which of the following can be a consequence of installing unverified software on a computer?

Installing unverified software can lead to various negative outcomes, one of the most common being an "Out of memory error." When unverified software is introduced to a computer, it may not be properly optimized or may have bugs that cause it to consume an excessive amount of system resources, particularly memory. This can lead the system to run out of usable memory, resulting in crashes or slow performance.

In contrast, trusted and verified software typically goes through rigorous testing to ensure it operates efficiently within the system's limits, minimizing the likelihood of such errors. Thus, the direct link between unverified software and memory issues highlights the importance of careful consideration when installing new programs.
