- Here's a look at three of the most dangerous viruses and worms of all time.
1. Love Hurts
- LoveLetter is the worm everyone learned to hate in spring 2000. The infection affected millions of computers and caused more damage than any other computer virus to date. The worm sent copies of itself via Microsoft Outlook's address book entries. The mail included an executable file attachment with the e-mail subject line, "ILOVEYOU." The worm had the ability to overwrite several types of files, including .gif and .jpg files. It modified the Internet Explorer start page and changed Registry keys. It also moved other files and hid MP3 files on affected systems. Visit Symantec's Security Response for instructions on how to remove LoveLetter.
- The Klez worm, which blends different virus traits, was first detected in October 2001. Klez distributes itself like a virus, but sometimes acts like a worm, other times like a Trojan horse. Klez isn't as destructive as other worms, but it is widespread, hard to exterminate--and still active. In fact, so far, no other virus has stayed in circulation quite like Klez. It spreads via open networks and e-mail--regardless of the e-mail program you use. Klez sometimes masquerades as a worm-removal tool. It may corrupt files and disable antivirus products. It pilfers data from a victim's e-mail address book, mixing and matching new senders and recipients for a new round of infection.
3. Malevolent Melissa
- The Melissa virus swamped corporate networks with a tidal wave of e-mail messages in March 1999. Through Microsoft Outlook, when a user opened an e-mail message containing an infected Word attachment, the virus was sent to the first 50 names in the user's address book. The e-mail fooled many recipients because it bore the name of someone the recipient knew and referred to a document they had allegedly requested.
- The Melissa virus was the first virus capable of hopping from one machine to another on its own. And it's another good example of a virus with multiple variants.
