Normally, I don't bother with giveaways because all they're only for the "giver". More numbers, more money. But I'd really like to win 1 of your giveaways. That's why I registered. And think about this, why would I go through all the time it takes to register, post, copy and post links if I thought it would disqualify me? That makes no sense.
First more importantly is the purpose of this thread.That being a well posted security config will get you more helpful replies,suggestions and recommendations.
The requirement for giveaways is there to foster some kind of forum interaction other than just joining the site to enter a giveaway.I will adjust the reply bans and your entries have been undeleted.
On to your config
As long as you are careful where you go and what you click on then yes Windows 10 built in security with UAC enabled & MBAE will work
I prefer to at least have an AV solution with Windows firewall.Avast free,Panda Free,Avira free are decent choices.
If you are looking for a Security Suite that won't slow down your Windows 10 ESET Smart Security is an excellent choice.My experience with Bitdefender is that it is a bit buggy and can impact your system and also your internet connection.
You could add a couple on demand scanners such as Malwarebytes Antimalware,ESET Online Scanner,Emsisoft Emergency Kit or Hitman Pro since these do not run in realtime you will see no system impact unless of course you are scanning.
There are a couple good free backup programs if your interested Macrium Reflect for one
I would consider adding CCleaner or Privazer.
Sandboxie is also a good addition to any config.
A password manager such as LastPass is also a good idea
You can also add uBlock Origin and HTTPS Everywhere to Chrome & Firefox
