A computer virus is a type of malicious software, or malware, that infects computers and corrupts their data and software. Worm, ILOVEYOU, SQL Slammer, Stuxnet, are some examples of computer viruses.The following are the main causes of a Computer Virus.
1. Infected Flash Drives or Disks:
Flash drives and disks are a big cause of spreading viruses. Flash drives and disks are used to transfer data from one computer to other. A virus can also be copied from one computer to other when the user copies infected files using flash drives and disks.
2. Email Attachments:
Most of the viruses spread through emails. Email attachment is a file that is sent along with an email, An email may contain an infected file attachment. Virus can spread if the users open and download such email attachment. It may harm the computer when it is activated.
