BleepingComputer.com: Hijackthis won't delete back up

Hi all im new here,

Ok, i accidentally installed winibluesoft and its a bleep to get rid of. I used Malwarebytes' Anti-Malware but only to little change. So i tried hijackthis. After a scan i saw an instance of winiblue so i deleted it, then i checked the backups under misc tools and deleted the back up. I closed it and restarted my computer, and the backup was still there, so deleted it again only to have it come back again after i closed the program then re opened it. So i deleted ALL the backups and they ALL came back. Can someone please tell me whats going on here?

Thanks
