I’m using Tracker software PDF Xchange reader, which has a (limited) capability of saving opened files. But now somehow when I try to do that, i.e. save a file with added annotations, for example, something just closes the reader. How do I open the avast log? I get no message - it’s been suggested that the behavior I’m seeing might be caused by my antivirus software, so I’m trying to look into it. I’ve found an Avast log file, but I cannot open it. The monthly report says everything is safe.
