What this program does:

The Vundo family of Trojans is one of the most common infections we find on user's computers. This infection can cause popups that include advertisements for rogue anti-spyware programs. Some common rogue antispyware programs that are advertised include WinFixer, SysProtect and WinAntiSpyware. Users are normally targeted by false positives, fake alerts, and warning of infections on their computer. An example of this type of misleading advertisement would be popups alerting users that they are infected with a blackworm virus. The most common method of infection is through outdated versions of the Sun Java platform; older versions are being exploited so it is important to firstly make sure that your Java software is fully up to date. This infection is normally detectable by users receiving popups when they use the Internet. Your antivirus program might also notify you via an alert that you have a Vundo Trojan on your computer.
The Vundo infection has evolved over time to include harder and harder protection methods so that it cannot be easily removed. These methods are random names, random autorun locations, random CLSIDs, and rootkits to hide these locations from removal tools. Due to this, specialized tools have been created in order to target this specific infection and remove it. The following guide will explain how to use the tool, and hopefully rid your system of this malware.
