adware ,malwarebyte,hitmanpro is not enough to clean hacker site!

hi,

on the threat  on which we discussed about nationzoom and the way to clean it , it is not working.

I have expressly downloaded a site which is called owesomehp and tried to clean it with adware software,junkware software,and tried to reset the defaults in advanced option of internet option ect. and then downloaded malwarebytes anti malware and tried to clean all viruses then I used hitmanpro to make sure that all malwares are cleaned. it didn't  cleared  this  hacker site 

but when I made system retore after all this steps it worked,an d I have the google back.

.

thanks

johan
