I did a test on my work system which is a SurfacePro4 with i5-6300U CPU @ 2.40GHz and 8,00 GB.
I had no administrator rights so I had to use the portable version.
Guess what, no slow downs, even with preview on and two active dictionaries and highlighting on, performance was good.
So I went back to my own system and disabled my AV again, no luck. Disabled some Defender settings, no luck.
Then I realized that my backup software Acronis Tue Image 2018 also offers some protection routines.
And there I found that the program flagged both Sigil.exe and QtWebEngineProcess.exe as suspicious processes. I have white-listed them and now all seems fine.
Thank you for all your patience and support.
