Hi,
Certainly what Neem said is true, about you get what you pay for. We disagree on which paid AV program you use, but certainly AVG free or paid does not and will not protect your computer adequately!
Period. I see computers come in all the time to my ship that are infected with all categories of viruses; Trojan, Spyware, Worm-Viruses, Day-Zero Attack viruses, and Ransomware running AVG. It used to be good at one time about 10 yrs. ago, but their management changed and the product is just not what it used to be. On the Malwarebytes, make sure you have updated to v3.06 the latest version. Even the old Malwarebytes is good and better than most of the AV programs at detecting spyware viruses, as that's the only viruses it looks for.
You might take a look at this post I wrote yesterday here for more information:
Is a anti-virus program needed?
Finally, on the Linux question: I have yet to see any Linux viruses in 15 years, and to me it seems more resistant to viruses than Macs are for example. And the Urban Myth you've no doubt heard that Macs never get viruses is of course BS (check
snopes.com for independent debunking of that particular Myth!). Macs represent about 5% of the worldwide 800 million computers on the Internet today, Linux PCs less than 1%. As Neem stated, virus authors and cybercriminals usually spend most of their time writing viruses for markets where they will do the most damage, or be able to collect the most money (via Extortion such as Ransomware). Why write a virus that only affects a few million computers or a few thousand (Macs & Linux PCs) when you can write a virus that affects 800 million computers at one shot! Think about it.
Hope that proves helpful.
