free antivirus is good for a basic protection (and please, don't use avg..., if that thing didn't founded a fake antivirus I don't know what does that thing can do), like if you share some information by pendrive, most of the times when I pluged some of my friends pendrive on my computer I got some warnings about virus, also one thing that I like is on avast, that it can detect malicious websites before loading (also it sucks too thinking my c++ projects are virus >.< [well some of they are like but anyway...])...
Well, Torrent for me is like aptoide for andoid, it can have some legal content on it (like ubuntu iso and the rip commodore os iso) but, I don't know people who download things from torrent files legally, just look at pirate bay recent files, all of them are illegal files...
But one thing is true, torrents today have much less virus than the e-mule days (even more because the windows protection on that days didn't even exist, a simple file could read ram data from other software, change it, dell windows boot,...
Too bad there isn't more oldschool virus, today it's just that files who stole passwords and read what's app conversations from a light app ¬¬

I don't too in most of the cases (at least only with windows software), and almost all the time I didn't got any warning, but I have some files with virus here. (not counting the websites that have a download to download your file, but before, you must avoid to install X files on your computer, then if you install babylon or others you'll try to uninstall, but when you uninstalled, you notice that you insalled a software called unsinstaller D:. For me that websites are worse than illegal torrent files)
