I have run Norton, JRT, TFC, CCleaner ADWCleaner and Malwarebytes. Nothing came up except some cookies.
I have been through the Virus Protocol on this site a couple of times before with Broni. I think this computer is prone to virus/malware sorts of issues as it is a shared computer - up to 4 people use it - and I cannot monitor everyone all the time.
This last incident was my husband reaching for the ESC button but hit the ON/OFF instead and perhaps a few other buttons at the same time. It has not been the same since. I managed to get it turned back on and then ran all the scans I mentioned above. It seemed slower but otherwise okay then the printing stuff started happening.
