Vundo is part of the Vundo and Virtumonde family of Trojans. This spyware is a rouge trojan and very bad stuff. If you are infected with vundo.dll then you need to remove it ASAP. This program goes out and downloads other malicious software onto your system. Common symptoms include a fake anti-virus program being installed onto your system, your home page being highjacked and a ton of pop-ups.
In order to remove this threat you have a few different choices. You can always just pay for someone to repair your system. The cost will vary but a few hundred bucks is not out of the question. This bad boy is hard to remove so it will cost you to have a pro do it. Online computer repair companies can remove it for a lot cheaper but your still looking to spend about 89 bucks on that. A good place for online repair is this Computer Repair Shop
Alternatively you can use a product like Spyware Doctor to remove this threat. Spyware Doctor can remove Vundo.dll from your system. You need to run the scan in safe mode in order to fully remove it but it does work. View our Vundo Removal Software page for more info.
A special free tool has been developed called Vundofix that works about 40% of the time at removing this threat. However most people find themselves infected again as soon as they reboot because Vundofix does not remove the other spyware programs and once you re-boot you re infected again. Vundofix does not offer active protection so that is why I don’t even bother using this tool anymore.
