@modnar Or do you use an extended kernel or an additional layer in your Windows XP installation where you have installed IOBit Malware Fighter 12.5? 

... 12.5 is for XP no doubt. However I already threw it off my box because it's too cut-down.

This statement is not really true. Although IOBit Malware Fighter Pro 12.5 can still be installed strangely enough under Windows XP, it says that this version is not compatible with Windows XP, if the user tries to enable real-time malware protection with IObit & Bitdefender engines or advanced protection against ransomware. It also advises to install IOBit Malware Fighter Pro 11.4 as the last XP-compatible version.  
And so, after all, this is what applies:

You have to download the last XP-compatible version 11.4.0. Here is the original website with this version: https://web.archive.org/web/20240830175125/https://www.iobit.com/de/malware-fighter.php
Download link: https://www.filepuma.com/de/download/iobit_malware_fighter_free_11.4.0.1360-40845/download/

Please test this version to find out how it works and whether it still receives definition updates or not!
