Antivirus – Best Antivirus for Ubuntu 18.04

18.04antivirus

I have upgraded into Ubuntu 18.04.2 LTS. I have worked primarily with Windows and secondarily with Ubuntu (14.04 and 16.04). I will work with Ubuntu 18.04 as my main Operational System (distribution). I want to ask if it is necessary to install an anti-virus and if the answer is affirmative what is the better choice (free of course:-)!).

This article suggests not to, but if nonetheless you wish to install AV software, ClamTK downloadable from the Ubuntu Software Centre will provide some peace of mind.

Alternatively as described here you can open a terminal and type:

sudo apt-get install clamtk

or load it through Synaptic Package Manager.

Ubuntu 18.04 – Fixing Brightness Problems

I also had this problem, but on different distributions the solution was different.

Solution provided by Anas Elazhar worked well until I switched to Xubuntu:

Open the file /etc/default/grub using gedit or any other text editor. Find below line.
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"  
Change above line to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor"

If it doesn't work for you either try to change acpi_backlight value to video:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=video"

Also create the file /usr/share/X11/xorg.conf.d/80-backlight.conf but content is slightly different from the file that you created:

Section "Device"
    Identifier  "Intel Graphics"
    Driver      "intel"
    Option      "AccelMethod"     "sna"
    Option      "Backlight"       "acpi_video0"
    BusID       "PCI:0:2:0"
EndSection

If combination acpi_backlight=video with this file doesn't work change acpi_backlight back to vendor.

And do not forget to run sudo update-grub command in terminal every time you change /etc/default/grub!

Virtualbox recently had a few problems with newer kernels. It might be worth trying to use the latest version directly from virtualbox.org.

To do so, please uninstall the Ubuntu version of Virtualbox, e.g. using apt:

$ sudo apt remove virtualbox

Then, download the package file from virtualbox.org and install it using a package manager of your choice, e.g. using dpkg:

$ sudo dpkg -i virtualbox-5.2_5.2.12-122591~Ubuntu~bionic_amd64.deb

Make sure all necessary dependencies are installed:

$ sudo apt-get install -f

Reboot and try running your VM again.
