I'm reading all new comments so don't hesitate to post a question about the file. If I don't have the answer perhaps another user can help you.
I have mfc45.dll and mfc45.dat (win7/32) on system32. I've also downloaded 2 other mfc45.dat files uploaded to a virus discussion Web site. All seem to be identified as corrupt PE executables. They all have the same size, 74703 bytes, but different content (binary compare). At the moment I'm mystified; I'll try to find a known good mfc45.dll and compare.

It seems that this file is needed for System Restore to work. So better to keep it... of course, the problem might be that a 'good' file is getting corrupted. See

The valid version of mfc45.dll was created by iolo technologies, who wrote System Mechanic.
http://www.avgforums.com/viewtopic.php?f=15&t=1352
They were planning to rewrite System Mechanic so as not to use this file, which triggers virus checkers.
So, if you've ever installed System Mechanic, that's where mfc45.* came from. I don't know that there's ever been malware with this filename, though some checkers will identify it as malware. I'd expect mfc45.dat, or any mfc45.* file, to be related.
I had installed System Mechanic on a machine, and later found mfc45.* on it, hence my comments previously. Two machines that have never had SM don't have the DLL.

I have mfc45.dll on my computer but have never installed system mechanic. Perhaps there is another executable that requires this file. PCmatic quarantined this file as well as a restore point (possibly created in conjunction with mfc45.dll)

Yes, I think the files are questionable. Some of the anti-virus software finds them https://freegamesonline.io
