I have an HP4600 printer. I cannot scan to my PC. Is it the McAfee that you installed? I need to scan something asap!
It is possible that the McAfee firewall is blocking the port used by the scanner but that is unlikely. If you go through the HP manual, see if there's a specific port used by the printer. Then see if we're blocking it by following the steps at McAfee Internet Security - How to Open a Port.
I would also recommend uninstalling and reinstalling the printer drivers in case there was info that needs to be entered again.
I have the HP 3050A all in one, minus fax and, with both Windows and Linux, I had to install software/drivers to get the scanner and wireless working properly. Without either, it printed, and then only with the cable attached to the printer and computer. Maybe the drivers/software are somewhat out of date and need to be updated.
