Malware – avast detected a virus during the Kali installation on a virtual box. How is that possible?

I installed kaly on a virtual box, on a W7 host, and during the upgrade / installation package avast found two threats, especially on a Mimikaz package.
The question is, how can avast "see" through the VM?

The package stops a bit on the host before it goes into the VM?
I always thought that 2 environments were isolated and separated.
I downloaded Kali from the official website
Thanks for your guesses.

8 – Security check: Some files and directories in your installation can be written to by the server

I am using Drupal 8 on a vps with the latest ispconfig / apache fastCGI.

Security Checker module reports: "Some files and directories in your installation may be writable by the server." and basically lists all of my files.

Now all files are set with the correct permissions: 644 for files, 755 for directories.

I suspect the problem is file ownership.
Ispconfig creates a new user for each site that belongs to a client group.

For this site all files belong to: web65: client0

which means: owner is web65 and group is client0

And I found that the www-data user is part of the client0 group.

Is that the problem? That the web server is a member of the client group?
And what would be the best solution?
I suspect this is a problem for all ispconfig users.

Any ideas?

8 – How to create a term programmatically during module installation

I am fairly new to Drupal 8. At the moment I am making a simple module that automatically installs 2 vocabularies each time the module is installed and automatically removes it each time the module is uninstalled. However, I had to enter the term individually each time the module was installed, and that is not efficient. Via this link: I learned how to do it. However, I just don't know where to put the PHP file and how to link it. What do I have to do to achieve this? Thanks a lot

Uninstalling – Uninstalling the beta camera app downloaded from an unknown installation source for Samsung Galaxy A50s (SM-A507FN).

assuming it works on my phone. However, the app crashed frequently and does not work.
I updated the phone's software so that it was updated to Android 10. Kernel 4.14.62-17887617.

This app was not installed in the Playstore, so I don't know how to uninstall it now.
Let me know how you can uninstall this app.

Software installation – Ubuntu utilities have disappeared but still appear in "View applications".

I am not sure where the problem is.

I have Ubuntu 18.04 Gnome.

Today some of my apps that were installed with the GUI Ubuntu software no longer started (for example: Thunderbird, Chromium, Discord). It is strange, I still have icons in "Show Applications", but when I click on them they start for a few seconds and then die.

I tried to remove and reinstall the broken apps but the APT manager says there are no such apps. I reinstalled Thunderbird from the command line and it works, but now I have two almost identical icons in Show App-s that worry about such ugliness and probably some mess under the hood.

More to say when I click on "Show details" on such a disappearing app icon, Ubuntu Software says "No application found".

I've searched for a while but haven't found any such problems or relevant solutions.

I update my system regularly. I assume that it is the fault of the Ubuntu Sofware Center. I noticed that the homepage was updated. Apparently Canonical recently rebuilt the App Center.

Does anyone have such problems? How do I fix it?

I must also mention that yesterday before the problem occurred, I mounted the SFTP file system from my other laptop with SSH server in Nautilus. Could it break apps?

Installation – Use drush to install a module at all locations on a multisite at the same time

I have a Drupal 8 multisite with 6 different sites. I want to install the admin toolbar on everyone in my local development environment (mamp / terminal / drush). I downloaded this module with Composer:

composer require drupal/admin_toolbar

Is there a single Drush command that installs this module in all six locations at the same time? If not, how can it be installed most efficiently?
