How do I remove Browsersafeguard malware or rockettab?

My wife's PC is infected with Browswersafeguard by rockettab or the rockettab software and I am trying to remove it.  It appears 360 does not remove it and I cannot remove it by uninstalling the program.  When I try to uninstall it via control panel is messes up my internet connection and does not uninstall as indicated by the web instructions on  line.  I'm trying to find a good free one shot tool if Norton will not remove it.  Any advice, she is running Win 8.1 and IE 11
