A user receives a call from someone claiming to be a technical support agent.

This is a scenario of a potential tech support scam, where a fraudster pretends to be a technical support agent and tries to trick the user into giving them access to the computer, personal information, or money. The user should not trust any unsolicited calls from unknown people claiming to be from tech support, as they might be trying to install malware, steal data, or charge for fake services. The user should only accept calls from known people, such as their IT department, their service provider, or their software vendor, and verify their identity before logging in to the computer. The user should also report any suspicious calls to the appropriate authorities or organizations.
