How Trojan.Agent.TMO Operates

Trojan horse malware like Trojan.Agent.TMO typically operates by exploiting vulnerabilities in software or tricking users into installing it. Once installed, it can create backdoors, allowing remote access to the infected computer. This can lead to a range of malicious activities, including data theft, keylogging, or the installation of additional malware. Trojans can also be used to disrupt system operation, causing crashes, freezes, or other stability issues. Understanding how Trojans operate is crucial for taking effective measures to protect your computer and data.
