Destructive Computer Viruses
Stuxnet
Stuxnet is a computer worm discovered in June 2010 that is believed to have been created by the United States and Israel to attack Iran's nuclear facilities.Stuxnet initially spreads via Microsoft Windows, and targets Siemens industrial software and equipment.It is the first discovered malware that spies on and subverts industrial systems, and the first to include a programmable logic controller (PLC) rootkit.
Zeus
Zeus is a Trojan horse that steals banking information by Man-in-the-browser keystroke logging and Form Grabbing. Zeus is spread mainly through drive-by downloads and phishing schemes. First identified in July 2007 when it was used to steal information from the United States Department of Transportation, it became more widespread in March 2009.
Conficker
Conficker, also known as Downup, Downadup and Kido, is a computer worm targeting the Microsoft Windows operating system that was first detected in November 2008. It uses flaws in Windows software and dictionary attacks on administrator passwords to propagate while forming a botnet, and has been unusually difficult to counter because of its combined use of many advanced malware techniques. The Conficker infected millions of computers including government, business and home computers in over 200 countries, making it the largest known computer worm infection since the 2003 Welchia.
Agent.btz
AWF (or Agent. AWF or Agent.btz) is a malicious Trojan Downloader affecting the Microsoft Windows Operating SystemAgent. AWF displays virus activity as it that replaces files on a user's computer with a copy of itself, and moves the original, legitimate file to a bak sub-folder. It is known to attempt to terminate security software, and the Trojan downloads a Backdoor onto the computer, allowing the attacker to further compromise the computer. It is also known to modify the Windows registry.
PoisonIvy
PoisonIvy (2005) PoisonIvy is a computer security nightmare; it allows the attacker to secretly control the infected user’s computer. Malware like PoisonIvy is known as a “remote access trojan,” because it provides full control to the perpetrator through a backdoor.
Mydoom
Mydoom, also known as W32.MyDoom@mm, Novarg, Mimail.R and Shimgapi is a computer worm affecting Microsoft Windows. It was first sighted on 26 January 2004. It became the fastest-spreading e-mail worm ever (as of January 2004), exceeding previous records set by the Sobig worm and ILOVEYOU.
Netsky
Netsky is a prolific family of computer worms which affect Microsoft Windows operating systems. The first variant appeared on Monday, February 16, 2004. The "B" variant was the first family member to find its way into mass distribution. It appeared on Wednesday, February 18, 2004. 18-year-old Sven Jaschan of Germany confessed to having written these, and other worms, such as Sasser.
Anna Kournikova
The Anna Kournikova computer worm was a computer worm authored by the Dutch programmer Jan de Wit on February 11, 2001. It was designed to trick email users into opening a mail message purportedly containing a picture of tennis player Anna Kournikova, while actually hiding a malicious program.
Sasser
Sasser is a computer worm that affects computers running vulnerable versions of the Microsoft operating systems Windows XP and Windows 2000. Sasser spreads by exploiting the system through a vulnerable network port (as do certain other worms). Thus it is particularly virulent in that it can spread without user intervention, but it is also easily stopped by a properly configured firewall or by downloading system updates from Windows Update.
Melissa virus
The Melissa virus, also known as "Mailissa", "Simpsons", "Kwyjibo", or "Kwejeebo", is a mass-mailing macro virus. As it is not a standalone program, it is not a worm.First found on March 26, 1999, Melissa shut down Internet E-mail systems that got clogged with infected e-mails propagating from the virus. Melissa was not originally designed for harm, but it overloaded servers and caused problems.
