I had a system crash and hppdfaxio.sys error message come up. With hours and hours of work, I found the source and deleted it. It still happens now. Anyone have advice for me? It's from the file hpfxfax.
Thanks for stopping by the HP Support Forums! I’d like to help with your issue!
Going through your post, I understand that you are getting "hppdfaxio.sys" error coming up on your PC. To assist you better, I need to know the model number of your PC. If unsure, check: http://hp.care/2bygf7l
Also, have you installed any printer/fax machine on your PC? If so, try removing the drivers completely.
Go to Control panel – Programs and feature – Select all the HP printer related entries and uninstall them.
Now go to Control panel – Devices and printer – Select all the printer entries and remove the device.
Press the "windows key" + "r" to get the "Run" window open - Type "printui.exe /s" (There is a space between .exe & /) and press enter.
Under print server properties, go to drivers - remove any entry there as well.
Again, go to the Run window, type – “c:/programdata” – Go to Hewlett Packard folder, remove any printer related folders & files.
Restart your computer.
If the issue persists, try installing and running some cleaner programs such as CCleaner. This will help you clean the left over registry files and hence will put a stop to the error messages.
Please let me know if this resolves the issue, or if you require further assistance!

I had worked through the issue myself. I use AVG as my virus program and pay for their remote help. They went through the computer but wouldn't delete the specified file since it was a .sys file. I did that myself, then the problems halted. I cleaned up all my Hp programs(maybe didn't dig as deep as you instructed). Then restarted the computer. I downloaded a new set of drivers and that file was back! I deleted it again. I'm back up and running now and thankfully AVG let me keep the program that they used to find the file. I check it daily right now to make sure nothing as been downloaded in the updates.
