Which free antivirus will you prefer to use with win 10?

I'd highly recommend F-Secure Jeff, it's lightweight, non-intrusive and does its job to a very high standard. Obviously if your browsing and downloading habits leave a lot to be desired it's not going to be foolproof, but on a near two year evaluation on my part it is exactly what you require in an AV. I've only ever personally seen one instance of F-Secure causing a BSOD too (other debuggers may well be able to attest to more) but given the regularity of other AVs causing BSODs that's a phenomenal record.

Thanks for the tip and I'll check that out. :)

F-Secure is what the company uses that I work for(of course they're using Win7) and being international on 6 continents they cannot afford and disruptions. And they're Kari's Homeboys out of Finland based in Helsinki. I like this when I visited their site.:

Policy on detecting spying programs developed by various governments

In late 2001, F-Secure Corporation received various queries on our standpoint regarding the possibility of spying programs developed by various governments.
Much of this discussion was generated by media coverage on rumored backdoor trojan known as "Magic Lantern", developed by FBI or NSA in USA. Discussion was increased as several US-based anti-virus vendors made comments implying they would on purpose leave a backdoor in their anti-virus products to allow such a spying program to work.
Thus, F-Secure Corporation would like to make known that we will not leave such backdoors to our F-Secure Anti-Virus products, regardless of the source of such tools. We have to draw a line with every sample we get regarding whether to detect it or not. This decision-making is influenced only by technical factors, and nothing else, but within the applicable laws and regulations, in our case meaning EU laws.
We will also be adding detection of any program we see that might be used for terrorist activity or to benefit organized crime.
We would like to state this for the record, as we have received queries regarding whether we would have the guts to detect something obviously made by a known violent mafia or terrorist organization. Yes we would.
F-Secure Corporation always aims to do what's best for our customers.

Sadly it IS a sign of OUR times.

I dont know if mentioned before, but all three products of Panda Security (Panda Antivirus pro, Panda Internet Security, Panda Global Protection/Gold Protection) are not yet compatible.

Also, the Poll asks about Free antivirus programs but neither ESET (in which I referred to) or F-Secure have Free versions as far as I know (correct me If I'm wrong).
Regards.

Free 6 month F-Secure Beta versions (6 month)
ESET Free 30 day Trial

OK OK semantics I know, but they are free.
Good job moderating Nick, we Forums folk do tend to branch off sometimes.

Which is why my first answer was Defender, which I'm using now. Now I've changed my mind and won't be using a free one come RTM so thought I'd update my opinion. I made it quite clear F-Secure was a paid AV.

I'm using Defender for the time being, but I have used AVG in the past.
