Last night, I got a virus from a download that turned out to be shady. This dumped a whole bunch of adware and some malware onto my computer and additionally installed a program called "Better Explorer." It appears that in the past, this was a legitimate Windows Explorer replacement but has since ceased development and had their domain lapse. I immediately went to get rid of all the junk and uninstalled/deleted all of the new junk, including Better Explorer.
Immediately after doing so, I found myself unable to use Windows Explorer, If I attempt to navigate to any folder beyond the drive header (ex. C:\), an error pops up reading [Address] Application not found.
Some quick googling brought me to this Toms Hardware thread where someone had similar issues and was told that
Better Explorer is not a theme, it's a replacement file manager for Windows Explorer. You should always make sure you know what you are installing and what it does.
When you installed BE, it replaced Windows Explorer as the default file manager by changing some registry entries.
When you uninstalled BE, those registry changes were not reversed, so Windows is still looking for BE. Hence the error "Application not found".
So far, in attempting to get Windows Explorer working again, I have tried
1. Running SFC /scannow
2. Running Avast and MBAM
3. Re-downloading (from a source that is not ostensibly malware.) The program works and I can navigate through my file structure, but Win Explorer still will not work, even after uninstalling it.
4. Deleting Better Explorer with Revo Uninstaller including removing registry entries made by it.
5. Running Windows Safety Scanner just in case MBAM missed any malware.
What I cannot do.
Well, here's the bad news, I had system restore off because I was running a full backup on a cold drive... which crapped out last month. No system restore to save my butt.
I assume that I need to find whatever registry entries point to Explorer.exe as the default way to access the file tree, but I am unfamiliar with the registry and don't really want to just go changing entries willy nilly.
