Angels have the Phone Box
Ugh - I hate that crap. Trojans, bringing more friends along for the ride....
Disk Mgmt looks okay.
Just so you know - once a system has had W10 installed on it (and activated), you can clean install W10 back on it as often as you like/need - so you don't have to do the W8>upgrade>W10 thing anymore. From the looks of your partitions, you did a clean install of W10, because I think a W8 install would have left a few more partitions on the drive, so I am a little confused(?) Unless you clean installed with a Win8.1Update - maybe that's why.
Do me a favor and run ADWCleaner, selecting Tools>Options and check all the reset options; see if it comes up with anything.
Might even want to check the box for prefetch as well.
