there's a program called "a-squared free" --- it does NOT include real-time protection.

I have minimal experience with a-squared.   But I believe Joe53 uses it, and recommends it.   Joe??

This seems confusing.

a-squared Free 3.0
Freeware! This program contains only the basic scanner. Background Guard, Automatic Updates, Scheduled Scans and HiJackFree are only available with a-squared Anti-Malware.

The summary was a little confusing.

A-squared Free 3.1 is a solid anti-trojan:

 

Easy to install, configure, update and run. Plays well with all my defenses, and very few false positives. Also a good user support forum. I can't think of any reason not to have it as a backup scanner.

 

I also can't think of any good reason to purchase the real-time version (unless the free version keeps detecting true trojans, perhaps).
