There are absolutely no viruses/trojans/malware in Stardock products. If obtained legally of course.

I purchased it here and it does the normal updates and I got this warning today, so I will just exclude this warning then.

Those all look like 7z files according to the screenshot. Not Stardock files.

If those came in a supposed Stardock package, it was only by you getting spoofed to another website presenting itself as Stardock..

There is no way that came via the real Stardock store.

The other explanation is that you downloaded a 'cracked' version.

Use the snipping tool in the start menu and take a capture of the files you downloaded. That will be definitive proof.
