In order to block a lot of unwanted content, such as tracking and malvertising, I usually install uBlock Origin.
This extension is a 'wide-spectrum blocker' which has proven to be very versatile and effective.
For managing all passwords, secure notes, and to maintain a good attitude of 'password hygiene', I use Bitwarden.
Bitwarden is available as both a paid and free plan. The paid plan offers a few welcome extras.
For easy but comprehensive file management, Total Commander can be considered a 'Swiss knife' of file management.
It also offers 'side by side' comparison of two files, a feature which I use a lot for creating the different scripts of UltimateKEYS.
As comprehensive image viewers, Irfanview (and XnView) can be considered the 'Swiss knives' of image viewers, supporting a wide range of formats.
Overall, IrfanView feels somewhat a bit snappier, although only XnView MP has support for AVIF at this time...
In the past, I used different antivirus products on Windows, but since 2017, I removed all third-party products. Now I rely entirely on Windows 10's built-in security (Windows Defender, default in Windows 10/8.1).
This is also the advice from a former Firefox developer, not to install any third-party security software on Windows 10.
Windows 10 (and 8.1) then automatically activates its built-in 'Windows Defender'. This antivirus is very stable and also turns out to be the most reliable integration concerning updates (and upgrades) for Windows itself.
