First you have to understand that all malicious programs, including viruses, trojans and other types of malicious software — like worms, spyware or even ransomware — are all types of malware.

What makes the difference is how the malware acts after infecting your machine. A virus is actually a type of malware that targets a system by copying itself from the original file that infected a machine. The virus's copies can corrupt files, programs and even other connected machines through its replication.



Trojans tend to disguise themselves as something legit that you'll download and install. Then, they get to work.

Trojans can lead the way for viruses and other types of malware to get into your system, but what makes them unique is the back door they create. So, you could actually load a trojan on your system and not see an attack until much later, when a hacker finally decides to make use of it.



Having a good antivirus program installed, keeping devices updated and not clicking questionable links and attachments are all good ways to keep your gadgets malware-free.
