It's good to hear the problem MAY be solved but I'm sorry you had problems with SuperAntispyware as I've got it installed on about 30 computers here.. No problems AT ALL with it.. I find it interesting that you feel it was causing the hibernation screen to load at startup.. Unfortunately, you've still not given us enough clues to help much more.. With SuperAntispyware, you have an option to prevent it from loading at startup. Did you do that? Do you have the newest version 184.108.40.2060 installed?
Still not information as to which other programs you're running which could be causing the issue.. Hopefully, you've used other antispyware programs such as Malwarebytes to scan your computer for potential malware...
As to uninstalling SuperAntispyware, I've not had such problems. Stop it from running at startup by adjusting the settings. Reboot the computer, then use the standard Add/Remove Programs section to remove it.
Hope this helps.
