Hello otto77!
Thanks for posting your configuration!
I have some tips for you that I wanted to provide you so that you can be more secure with your configuration.
The first thing that I'd like for you to do is to ensure that your firewall is enabled. You do not want to keep a door open for lots of stuff to come right on in or out of your system. The firewall inside of Windows 10 isn't all that bad and it is better to have this enabled than disabled. AVG IS has a firewall inside it too if I'm not correct. I'd update your configuration to include this being enabled once you enable either AVG's firewall feature or Windows.
I would recommend that you try EEK as an on-demand scanner as this would be much better as a second opinion scanner. Plus EEK is free! Another additional scanner that I would recommend is using Norton Power Eraser. This is another free tool that you can have in your tool chest.
I would recommend that you implement a backup plan. There is two pieces of software that are both free: Anomi Backupper and Macrium Reflect. Both are tried and true pieces of software that work excellent. It is best to have a backup plan if your OS starts getting unknown issues if your computer gets a virus that cannot easily be removed and other issues.
For extensions, I would highly recommend HTTPS Everywhere.
Link:
HTTPS Everywhere
Description:
HTTPS Everywhere is an extension created by EFF and the Tor Project which automatically switches thousands of sites from insecure "HTTP" to secure "https". It will protect you against many forms of surveillance and account hijacking, and some forms of censorship.
Next up I'd recommend using uBlockOrigin:
Link:
uBlock Origin
Description: easy on memory and CPU footprint, and yet can load and enforce thousands of more filters than other popular blockers out there.
I hope my advice will help you become more secure! Thanks again for sharing your configuration with us. Please feel free to ask us questions.
