How to remove en.softonic malware that appears on desktop periodically

A kind of malware has somehow gotten onto my win 10 PC. What I get is a small advertisment that pops up in the bottom right on my desktop... When I turn it off (clicking the corner X). It comes back again some time later but with different content.

I haven't timed it but seems lake maybe a 1/2 hr.

I've googled extensively but all the instructions I've found, tell you to use the windows uninstaller to uninstall softonic. And maybe some manual clean up after the uninstall. But there is nothing installed with `softonic' in its name and even when the ad is running there is no process running with softonic in its name.

All the google hits appear to assume the windows uninstaller will know about softonic. Even the manual parts of some of the hits appear to assume you have been successful in unintalling it.

The instructions also suggest several free malware removal products and claim any of them will remove it.
`Zema Anti-malware', `MalwareBytes' and `AdwCleaner'

I tried all those listed in one of the instruction sets, ran the scan but none of them found whatever is running the little softonic pop up ad.

This type of malware apparently falls into a category called a `PUP'.

I never found in the google hits what expected would be there somewhere. A list of steps to remove something like this by hand.

Can anyone here advise me?

 

Calendar Notifications Stopped Working / Appearing

My Calendar notifications have stopped working.
The Calendar App is working fine and I have no problem adding events.
When I navigate to Settings > System > Notifications the Calendar App does not appear. See screen shot below.
I am used to relying on the Calendar notifications or reminders, any suggestions are appreciated.

 

All text files appear corrupted

This appears to be some type of crypto malware at first glance. There are methods of removal and recovery available, but there are many variants of such malware. I would suggest to stop using your computer immediately and have the hard drive serviced by an experienced IT repair professional.

You may be able to recover older versions of your files in OneDrive that are not corrupted following these steps provided by Microsoft.
