Latest update das said pdftp.exe and pdfind.exe are trojans, tried to reload still takes out the program exe files.
I’ve the equivalent files in v7 of PD and Avast accepts those.
Have you tried going to File System Shield and adding those two files in Exclusions?
I had to do this with a couple of files from Superkeys as Avast identified an .exe and a .dll as malware.
