Trojan

This is currently the most widespread form of computer malware. The Trojan Horses are famous for their versatile abilities and the disguise tactics their creators use to distribute them. The Trojans are known for tricking the user into downloading them by presenting themselves under the guise of a seemingly normal program or app. This makes the infections with these viruses difficult to notice without a security program. In addition, they also tend to keep their files and system entries disguised, which is why most Trojan Horse victims may need an antivirus or anti-malware program to remove the virus. That being said, it’s still typically possible to remove a Trojan manually if you are careful.
