That is why I have Avast Internet Security running. I also am behind a Nat Router.
As good as AVAST is, something could sneak by, such as a new nasty that AVAST hasn't written a definition for yet. Keep in mind that AVs, etc. are more retroactive than proactive; they mostly respond to known nasties. If set correctly, UAC will alert you every time a process is being started so it will be difficult to impossible for a nasty to start a process without your knowledge as long as you allow UAC to do its thing and you take the extra second to read the popup before clicking on it.

You could also use Winpatrol that also will warn, if the system settings changed, as backup for malware bypassing UAC.

An analogy, although not exactly accurate:
Linux = SUDO
Windows = UAC

In Linux, you never (usually) run with administrator privileges - hence you are required to elevate certain commands using SUDO.

https://en.wikipedia.org/wiki/Sudo
From the operation perspective, SUDO is the same as UAC, as long as one needs to enter the password for the UAC. Minor differences, but both of them do the same...

Not being able to login as root in Linux Mint actually ticked me off and enabled root login. I seldom login as root, but it is my choice and not some developer(s) somewhere.

I do find interesting that we are discussing UAC on/off, while in the Linux world it is a given that the UAC/SUDO is turned on and should not be disabled. I am not even sure that it can be disabled...

But...

AV vendors have been integrating heuristic/ behavioral based protection, in addition to the signature based detection. Kaspersky and BitDefender had been the leading companies in heuristic/ behavioral protection, stopping about 97% of the new malware without signatures. Avast is lagging behind them, at around 87%...

I have never had a malware problem, I have never gotten a virus. I have a Firewall (not Windows). I just do not need a machine to do the thinking for me and tell me if it is OK to install this or that, BTW AIS has an auto sandbox which basically does the same thing.

Malware can routinely bypass/disable UAC and my system also has MS EMET running to block buffer-overflows in internet connected and other applications.
I would be interested in seeing a write up of malware bypassing the UAC (when it is set to the max level) without user interaction. I've searched for same and I must not be using the right search terms.

UAC may be useful for some, but I'll take my chances.
But you are not just taking chances for yourself - you are on the internet, not on an island. If your computer becomes infected, it impacts others, not just you. Malware that fraudulently earns money by "clicking thru" to websites costs us all money.

I just cleaned 2 such infections from a friend's computer that the av tools (Norton and later MSE) and Malwarebytes never saw. As best I can tell, this computer had been infected for more than a year.

If you get infected with a well written app, you (and your antivirus app) will never know that it is there. An offline scanner like WDO might find it, but a regular antivirus tool won't. There is no way of knowing if you were never infected with malware.

edit: BTW, I'm not attempting to get you to use the UAC. We are just chatting. :-)
