I no longer use AdAware so cannot say much for sure on these but these files C:\SDFix\apps\cliptext.exe have not been identified as a threat anywhere but AdAware, in fact all other sites I checked stated that a cliptext.exe file was all right and generally refers to an installer program, in this case for SDFix.
The MRU listings are Most Recently Used and can be ignored, you don't even have to check that tab. You can have anything show up in there...a letter to your Mom, a game, a photo edit, any number of things. Those items you just ignore because they disappear on their own usually and are not considered infected files.
