Have just been back on with a customer that was having issues last week with a HP Officejet and Web Protection.
Following installing the latest update, the printer setup wizard would find the printer this time, it would however only install the fax not the actual printer.
The steps I took to get this working were as follows:
Uninstall all HP printer drivers/software
Deactivate and uninstall MBAM
Ran CCleaner and removed left over HP/MBAM registry entries (take a backup first)
Re-installed HP software and drivers from website - printer installed and working fine
Re-installed latest MBAM and activate, reboot - printer still working ok so far
