09 Aug What Is the Difference between Trojans, Viruses, and Worms
Whether you’re a seasoned expert in network performance monitoring, or you’re just a newbie, it’s extremely important to know the difference between Trojans, Viruses, and Worms. These online threats can quickly take down an entire organization and, therefore, IT professionals on any level should be well-versed in their differences and the type of damage that they can cause to any computer or corporate network.
Viruses
Viruses typically are attached to an email or file or program and infect each computer one at a time. Viruses can quickly spread through a network and replicate themselves, causing more problems along the way. Many times viruses are executable files that are mistakenly run by users.
Worms
Worms are very similar to viruses in that they replicate themselves, but they don’t access a certain file or program. They use computer networks to send malicious programs to other computers, quickly spreading across a network. Worms are extremely hard to detect and can do major damage to all types of computers, even servers.
Trojans
While Trojans may seem harmless, they can cause significant problems. Trojans are frequently disguised as legitimate software, such as pop up blockers, when in reality they can make changes to your computer, even deleting files in some cases.
