Polymorphic Virus |\
An advanced version of an encrypted virus that changes itself
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
everytime its executed by trying to morph the way the code
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
looks so the sign-based antivirus cant defect it

|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
Easter Egg |\
not a virus , trick user to infect themselves
|\ |\ |\ |\ |\ |\ |\ |\
Worms
A malware like a virus but it's able to replicate itself without user
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
interaction that cause disruptions to network traffic, computer
|\ |\ |\ |\ |\ |\ |\ |\
activities, and cause a system to crash or slow down
|\ |\ |\ |\ |\ |\ |\ |\ |\
Trojans
A malware disguised as a piece of harmless software to preform
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
desired and malicious functions to infect a system.
