If a user experiences multiple browser pages opening unintentionally, which action should be taken?

When a user experiences multiple browser pages opening unintentionally, this behavior is commonly associated with adware or malicious software that can hijack browser functions. Installing anti-malware software is a proactive and effective measure to scan for and remove malicious software that may be causing this issue. Anti-malware software specifically targets various forms of malware, including adware, and can help eliminate unwanted programs that contribute to such erratic browsing behavior.

Updating antivirus definitions is important for keeping existing antivirus software effective against the latest threats, but it may not directly address the specific issue of unwanted browser pages opening. Similarly, enabling the pop-up blocker can prevent some types of unwanted pop-ups, but it won't eliminate any underlying malware that is responsible for the behavior. Rebooting the PC can sometimes help refresh system processes, but it does not resolve the cause of the problem and might only provide a temporary reprieve.

Thus, installing anti-malware software not only addresses the immediate issue but also enhances overall system security by detecting and removing any malicious entities that may have been introduced.
