A user's company-issued mobile device is having issues browsing the internet. Many news articles found by following social media links have missing images, and top search results for product purchasing produce errors when followed. Which of the following is most likely causing these symptoms?

Device encryption secures the data on a mobile device by encoding it, preventing unauthorized access. While it protects sensitive information, it does not influence the ability to browse the internet or render web content, and thus would not cause the symptoms described.

Antivirus software is intended to detect and eliminate malware, as well as protect the device from threats. While it may occasionally interfere with certain websites or downloads, it typically does not cause missing images or link errors, which are more indicative of content filtering.

Missing updates can lead to performance issues or security vulnerabilities on a device. However, they would not specifically cause problems with image rendering or errors in browsing. Generally, updates improve functionality rather than restrict access to content, making this choice less likely the cause of the symptoms reported.
