Hi captainawesum,
Before you do some damage by running Tools and especially Gmer
please have a look at the Properies of the file
D3DIM700.DLL belongs to Microsoft Direct3D graphics and it is the system file and in the right location C:\Windows\system32\ (at least for XP)
Please check for Vista in particular
Submit the file for analysis to Comodo developers.
Please read this thread Sure we don't rely on file names only and any file can be compromized , but you have to investigate first because removing files from system area even if they are substituted may not be as trivial as deleting them.
Probably not with this particular file , but you can damage your system inoperable by blindly quarantining or deleting files from C:\Windows ... ...\system32\ etc.
My regards
P.S. Properties here:C:\Windows\system32\d3dim700.dll
