Problems during Windows Update

I'm not sure of the exact date, but it was around September 10th. I do remember that there was a security update to Net.Framework4.5.1. During the update the screen went blank and the computer died and then Re-Booted. That's when everything went sideways. I couldn't get any Updates for a couple but kept getting the notice that Net.Framework4.5.1 needed to be repaired. I scanned with Malwarebytes Pro, and every time I did I got a report that "Astromenda" was in 2 registry entries. I've tried everything I could think of (they were Quarantined each time) and still showed up on every scan. Along with that, I kept losing Desktop Icons and those remaining were always rearranged. And then I began getting a new install of Windows Live Mail- minus all my saved folders and any mail or anything else. It was a brand new program!! It did recover some things that I tried to reorganize twice but then I'd lose all again. I stopped the Update service and deleted all the downloads and after restarting MUS, I was able to begin downloading again. There were almost a Gigabite of downloads. Also, I did a Smart Defrag (from IOBit, and there were 18,099 fragments in C:. There were a lot more things that were haywire, but now the Updates have gotten done and hopefully things will begin to get back to normal. I haven't tried opening Windows Live Mail Again so that could be more fun to come. Has anyone experienced anything similar or had any experience or success with eradicating "Astromende"??
