My computer runs very slowly at start-up lately and I get this small box that has a header of "lxrautorun" with no message in it, but it has a button to "exit". I can't find this on the Norton website, but I did find a patch to remove it on file.net which states it is malware and should be removed, that it has a 49% dangerous rating. But of course I don't want to start downloading something from an unknown website. Anyone know what this is? Please advise.
