These are not online scanners, so they are not considered in the article. But yes, they should be better than online scanners because they are installed locally and have higher system priveledges than online scanners.
I don't use any on demand scanners or online scanners. I prefer sweeping for malware the manual way with tools like Mandiant Redline (memory forensics) as it is more thorough

The manual way is more time consuming, so I run them only rarely. To me all these online scanners etc. are not useful at all because my computer is almost impossible to be infected. I have configured my computer's security polices and security systems to be almost watertight by following those guidlines from ASD and NIST.
