How is the printer physically connected: USB, network (wired, wireless)? You should start by checking those connections and configurations.
However, my surmise is that something else was downloaded and installed along with Spyhunter and that that something changed your default printer.
Making the default printer some "save" process.
Or some other coincidental upgrade or install may have done the same thing.
Go into Devices and Printers and check the configuration. Likewise check any default settings (i.e., the printer) in the applications being used.
Make sure that the desired printer is the default printing device.
