Which Free AV has no nags?

I often fix computers for people (a part time job) and obviously I always want to install an AV for them, since now I can no longer install the following, I found that 360 Internet Security is the only decent free solution with no nags, no ads, no facebook likes, etc.

Am I correct in this or is there any other good AV I've missed?

I don't want to compare them, just want to know what are my options if you know what I mean.

So far..

Avira AV = has that unwanted Essentials thingie
Avast = looks like a cartoony scam app with lots of nags to upgrade
Avira = Link to upgrade to pro at the bottom which I don't want my client accidentally clicking, facebook like button, etc
Panda Cloud AV = requires registration, not as easy to install as it was a few months back

I loved how 360 IS just installed so quickly, has good detection rates as I've seen on AV comparatives and is light.

Anything else I might consider to keep in my software library?

Bitdefender Free
Forticlient - not so lightweight
Baidu Antivirus

Can't we still disable the popups in Avast! AV? I haven't laid my hands on the newest version but I could remember it was possible back there.
