whenever I search something, theres always the same 134.4 kb mp3 with the name of what i was typing. also, i typed in random jibberish and the same title is shown of 134.4 kb. is this only effecting limewire or do i have some keylogger? (i have NEVER downloaded the 134.4 kb files)

It's spam. To find out more, see these links:

I think from memory the 134 KB files are mp3 spam.
