The possibility, that this has to do with limewire is small. I can think of two ways, how you got this system hijacker on your computer.
The first is, you may have downloaded and viewed a .exe, .doc, .rtf, .vbs or similar file through a filesharer. If it was this, you cannot blame anyone but yourself.
The second is a website, that exploits vulnerabilities in Internet explorer (ActiveX, Jscript->ActiveX and so on) to edit your registry and run code on your computer. On the lavasoft forum there is a thread about such a site, that behaves similar to what you described and uses a misspelled name of a popular domain, to trap surfers by a typo. Removing this can be tricky, but people can help you, if you post more technical details about it.
