ive recently got this bar up the top of IE, and cant seem to be rid of it.
i can turn if off through view>toolbars, but once i open another page, its back again
Well it was not limewire itself, but rather something you downloaded off of limewire. I am 100% sure that limewire is not bundled with any adware/spyware. I know Kazaa is bundled with it tho.
My guess is that you tried to download a program and it did not work, but when you executed it, the file went ahead and installed spyware.
If you download MS spyware beta, it will find it and you can delete it. It is a spyware program! Just google Microsoft spyware and do the Genuine Check thingy. Good program from MS!
