Subsequent file downloads are blocked without notification and just don't arrive

Windows 11 PC with Kaspersky Premium installed and up to date
Edge, Chrome & Firefox installed and all exhibit the same problem
If I download a PDF bank statement from the bank it works fine but then if I try to download another it fails unless I reboot
So if I want to download all my last 12 months bank statements for the tax man then I have to reboot 11 times !
The same problem occurs with CSV files and XLSX files and is the same using ay of my browsers
If any one has any ideas how to resolve this issue I would be most grateful
A dozen or so reboots during the day is very tedious
Kaspersky Premium installation disables Windows Defender so it can't be that
Also if I exit / close Kaspersky it still leaves stuff running in the background despite using task manager to close the obvious
Any help much appreciated
