Re: [Trisquel-users] Anti-virus software?

[dhood]

A firewall is always a good plan. The most straightforward one is Gufw, it is  
in the repos. I also recommend AppArmor, https everywhere (browser  
extension), and a VPN at minimum. I personally run Privacy Badger, and an  
adblocker with my browser additionally.

There is a good, though slightly old chat about online security here for your  
perusal: https://trisquel.info/en/forum/firewall-trisquel
