What Is Trojan.Startpage.ACP?

Trojan.Startpage.ACP is a type of malware that falls under the category of Trojans, which are malicious programs designed to gain unauthorized access to a computer system. The name "Trojan" is derived from the legendary Trojan Horse, symbolizing how these malwares deceive users by disguising themselves as legitimate software.

How Trojan.Startpage.ACP Operates

Once installed, they can perform a variety of malicious actions, including but not limited to, stealing personal data, installing additional malware, or providing a backdoor for remote access to the infected system. The exact mechanisms can vary widely, but the end goal is usually to compromise the security and privacy of the user's system and data.

Symptoms of Infection

Symptoms of a Trojan infection can be subtle and may not always be immediately apparent. Common indicators include unusual system behavior, such as slow performance, frequent crashes, or unfamiliar programs and icons.
