When I installed Kaspersky a popup said something like "Please remove incompatible software". Then a few hours later, again. Each time it said that I clicked 'delete' and it said 'restart your computer'. Then a few hours later, again.
Now, after a few days, I have to ask how to stop this.
I've never had Norton though it may have been pre installed. I searched through the Windows folder and registry and deleted anything that might trigger that but still it pops up.
Windows 10 version 21H1
Kaspersky version 184.108.40.2061
