Cannot set web browsers as defaults

Hello, a recent malware bundle messed up the two browsers I use, Internet Explorer and Google Chrome. I am certain the malware is gone, though I had to reinstall Chrome and disable/re-enable Internet Explorer but now I cannot set either one as my default browser. They do not show up in the list of defaults in "set your default programs." I am running Windows 8.1 and using Internet Explorer 11 and the newest Chrome.

Its starting to look bleak as there are not many options I have found to fix this which if I had to guess would probably be something in the registry and that's going take someone with good knowledge of Explorer and Chrome, any help would be appreciated thanks.
