Hi. Some viruses just disable or suspend PH when you try to run it on infected PC. I was helping ppl with virus removal and for the last 3 months almost every malware/virus/miner tried to stop PH process, even if i tried to rename executable file. I have read some forums where the viruses code is posted and looks like most of them are trying to check process name and window title when you try to run any .exe. To counter this, Dr.Web CureIt and Kaspersky VRT have the protection - every time you download them from official sites - you get unique .exe name, etc.
Please consider to add a feature to download latest PH with random .exe name, that launches random window title and show up as randomly named process in the Task Manager. This will definitely help to use Process Hacker when it is really needed. And thank you for that awesome software.
