After reading this I would never again be able to trust Avast: http://www.howtogeek.com/199829/avast-antivirus-was-spying-on-you-with-adware-until-this-week/

I have seen that and even posted on 8forums, or Tenforums somewhere and got rattled too, a company and it's program that is supposed to shield you from stuff like that, doing same thing !!!!!
I choose free Bitdeffender for W 10 now but I'm not satisfied with user interface, not enough customizing can be done on it. As far as I have seen, they are not doing it since newest 2015 version but still..... and to boot they didn't even bother making it compatible with OS that over million people started using in just few days. As a many years' user I protested and asked for explanation but no answer yet. Sure way to ruin a company, customer NEGLECT. Their commercial SW is sure to suffer too.

So, now that Avast is out, what is the next good FREE AV?

Personally I would say Comodo Internet Security, however I am biased in that question. Well I'd say the Firewall and Defense+ (HIPS / Sandbox) are good but I would also say the anti-virus (as in signature based) isn't on par with certain other products.

If you or anyone else decides to try it, during install you'll have a "Custom installation" near the bottom left corner, click this in order to disable additional products that are bundled that you may not want to install, like Comodo Dragon (Chromium based browser designed for better security), GeekBuddy (Support sorta, useless unless you pay for the product) and PrivDog (Due to ToS can't talk about what it does, has to do with ads, don't want to risk it by saying more than that - Also I don't know the privacy regards to it, may even track URLs like the Avast extension did, couldn't tell you.)
Also note that during install you will be asked if you want to set Comodo SecureDNS as your DNS, you will also be asked to set Yahoo as your homepage, I'd recommend disabling these, the DNS isn't the fastest and not very good at its job, the yahoo homepage is probably self explanatory. You will also be asked if you want to enable the Cloud as well as anonymous usage reporting or something like that, you should disable these if you are interested in privacy, while they are supposed to be anonymous as far as I can tell, how can they really guarantee that if the files in question contain personal information?

Comodo Internet Security may have a high learning curve and certain things that would seem to be easy to configure are unnecessarily hard and complex to configure, no examples on the top of my mind but from personal experience doing in-depth rules for HIPS and Firewall takes extra forethought and testing.

I fully admit that I am biased in this question, I've tried to be as objective as possible in my reply but I only have experience with CIS and hence can't say anything about any other products. There are problems with CIS, it isn't perfect or even close to being perfect in my personal opinion and I have an issue with how certain things are handled but it is still the best Security product that I have personally ever tried, that said I haven't tried many, pretty much just AVG, Norton 360, PC... uhh.. .. Was it PC Doctor? and then G Data - although my knowledge of them is very much outdated.

Ah those age old rivalries, Ford or Chevy, in Toronto I had "Ford only" parking sign and my neighbor "Chevy only", Hamburger or hot dog, AMD or Intel. luckily there are so many AVs to choose from. More experiences we hear, better but not easier is to choose from. My latest try will be Bitdefender, free edition. It's on top in rankings but does not look as customizable as some other ones. I'm not some kind of control freak but I like to have choices as to what,when and where is scanned, stopped or let through.

I'm using BitDefender right now.
I might get kapersky when I upgrade to Win10..

May I ask for some experiences with it ?
