AntiSpam OE Hook Launcher is using all my CPU - how do i disable?

Hello,

asolench.exe *32 - AntiSpam OE Hook Launcher has started using all my CPU & memory. It's recently started to run automatically and I cannot turn it off. I have tried to end the process from within the task manager but 'access denied'.

It is now consistently hogging between 45-70% of PCU and upwards pf 470,000K memory. See screenshots below. Is there a setting within Norton that can disable this function?

Thanks
