Hi!! I have the same problem, with all of the navigators I use (Google Chrome, Microsoft Edge, Mozila) I could not navigate through internet. I was trying to do the steps for this solution but in my case I am not able to see the "Report" Folder. Therefore, I cannot change the name.
C:\ProgramData\Kaspersky Lab\AVP21.3\ and rename the folder Report to Report1
The folders I have inside the AVP21.3 are the ones seen in the attached image. Do I have to change something in this folder or not? At the moment I had to disable the KIS in order to be able to work.
