There are some newer anti-malware apps that I have tried, but I never mention them, as they are terrible and have major issues with false positives.
Some examples are Malware Crusher and Free Malware Removal Tool. Free Malware Removal Tool is a free version of Malware Crusher, with slightly lower detection rates. They both are very good at detecting PUPs, but have major issues with deliberate false positives. For example, they detect Total Uninstall as malware and they used to detect Steam client as malware. It's worth noting that they are published by tech support scammers PCVARK.
There's some discussion about PCVARK in this YouTube video.
I also come across new antiviruses from time to time. Almost always they are using Avira's scan engine and are just really bad products, which lack important features like proactive protection.
