A Trojan virus is a type of malware that disguises itself as a legitimate program or file, but once installed, it gives attackers remote access to your computer or network. Unlike other malware, Trojan viruses do not self-replicate, but they can cause significant damage by allowing attackers to steal sensitive information, install additional malware, or disrupt system operations.
Trojan viruses have been around for decades, and they continue to be a major threat to computer users. They are often spread through phishing emails, malicious websites, or infected USB drives. Once installed, Trojan viruses can be difficult to detect, as they often hide their presence from traditional antivirus software.
