! How to protect your computer from virus.

!! University anti-virus software
I checked [[anti-virus software|https://www.cc.tsukuba.ac.jp/wp_e/service/software-license/]] which is provided from university,
{{br}}
and found that it was not suitable to ubuntu
(only for CentOS or other distributions.)

!! Current approaches
{{br}}After further searching, I found 2 approaches.
{{br}} approach 1,
ubuntu have [[net filter subsystem|https://help.ubuntu.com/lts/serverguide/firewall.html]] in itself.

{{br}}But firewall is off or unactivated in default setting,
{{br}}so we can activate ubuntu firewall system using "gufw" software.
{{br}}(if you do not understand what firewall is, plz search! )

{{br}}*** In order to make use of ubuntu net filter,
we always keep our ubuntu updated.

{{br}} approach 2
{{br}}We can use virus scan software. I tried ClamAV.
{{br}}Using this software, we can manually search
{{br}}if my computer have any virus or not.

sudo apt install clamav

method 1 <- I tried this
mkdir ~/virus
clamscan -r -i --move=$HOME/virus .
or
method 2
clamscan --infected --recursive
clamscan --infected --remove --recursive

!! In the end
{{br}}finally even you already tried these solutions,
{{br}}still we are not so sure of the risk of the malware.
{{br}}Let's always try to find best way!!!
