PC viruses pop up and spread as fast as wildfire. We have been able to compile an in-depth post on what the eight most common PC viruses are to date!

  1. Chernobyl Virus (CIH)

This deadly virus emerged in 1998 and was set off each year on the anniversary of the Chernobyl nuclear disaster dated 26th April.

  1. Anna Kournikova PC Virus

The virus was created on the 11th February 2001. Email users would open an email that supposedly contained an image of Anna Kournikova, a well-known tennis player. Once opened, the virus would spread through stealing the contact information in the email address book of the email user.

  1. ILOVEYOU Computer Worm

This worm attacked several computers worldwide starting from the 5th May 2000. Countries affected were mainly the Philippines, Hong Kong, Europe, and the USA. The worm was sent out in emails with the subject heading as ILOVEYOU. While the Malware remained undetected, once an attachment opened, other email users found in address books became targets.

  1. Melissa PC Macro Virus

Melissa virus was written in a programming language which installed itself inside software apps. Reports surfaced that the Melissa virus resulted in $80 million worth in damages to PCs and networks.

  1. Blaster Worm

Blaster spread on computers that used operating systems such as Windows XP and Windows 2000 in late 2003. Most large corporations, with minimal firewall protections in place, suffered greatly as this enabled the worm to spread rapidly.

  1. Netsky Worm

Netsky made an appearance in early 2004 by affecting Microsoft Windows operating systems. It was sent out through email with an infected attachment which resulted in compromising other email users by stealing stored email addresses on one’s PC.

  1. OSX/RSPlug Trojan Horse

Discovered in late 2007, targeting the Mac OS X operating systems. The Trojan was found in pornographic sites which also lead to phishing websites.
