Is Bearfoos a Virus?
Bearfoos also known as Trojan:Win32/Bearfoos.B!ml is classified as a trojan horse.
What Is the Difference Between a Computer Virus and a Trojan Horse?
A computer virus is malicious software that runs on a computer and replicates itself in order to spread and cause damage to the system. It can slow down the computer’s performance, steal information, and display pop-up ads. A trojan horse, on the other hand, is a type of malicious software disguised as a legitimate application that can allow a cyber attacker to gain access to a user’s system, steal data, or perform other malicious activities.
While both can damage a computer system, the effects of a virus are generally more easily noticed as the virus will attempt to spread itself to other computers by replicating itself, whereas, trojans such as Bearfoos may stay on the system undetected, slowly causing havoc.
