There are different types of viruses from simple viruses to very disastrous ones. Trojans, malware, and ransomware to name a few viruses that are very common nowadays.

Viruses spread like wildfire and can damage your computer so badly. Each virus was created with a purpose. Each purpose is different. Some viruses can damage your files.
