Mini tool partition wizard a threat?

I have Mini Tool Partition Wizard on all my pc's. When I opened the free version on this pc, it prompted me to update to the latest version which was not unexpected, and as I went through the update process which was exactly the same as updates in the past, Windows Security killed it dead. Trying to find out more, I couldn't find any reference to the actual name of the program. Any thoughts?

Upload the installer to VirusTotal see what it makes of it

I can't, the program has vanished from my machine, I even looked in control panel. Tomorrow, I will open up the program in another of my pc's and see if the same thing happens.

Please read the last community remark.

I have found threat references on Windows security, and have followed the instructions to scam and remove them . This took four short scans, now there are no threats detected.
I will now follow Roland's link and re install the program.
I was just opening the MTPW and followed the prompt to update when this happened, and the update proceeded exactly the same as frequent earlier updates of the program have gone. I scan frequently using the full Windows Security scans, and their offline scans, in addition to Malwarebytes free. The last scans were done on the same day as the problems arised.

Having reinstalled MTPW from Roland's link, and unticked a lot of unwanted extras as it proceeded, the program opened as normal and my disc drives showed up as expected. Windows Security immediately showed two potential threats.
I ran Malwarebytes and two addware related items showed up, which I quarantined. A further scan with W S was clear.

I have just run MTPW and their other program, Shadowmaker, without any interruptions from WS, so, hopefully things may have settled down. I will now try an offline scan and see what happens.

Since promising to try the Windows offline scan, I have tried and failed four times to get it to start, a full scan worked ok

Surprisingly, I've been using it for so long without knowing it's malicious software. But anyway, it has helped me partition hard drives quite quickly and for free. The latest report from VirusTotal records it as 25/70 points.
