Antispam OE Hook Launcher

Hi,

I have a problem with Antispam OE Hook Launcher which is increasingly hogging resources on my pc.

If I leave the computer on, i find two versions of the program running and using up to 100 per cent of processing power.  I even get  performance alerts from NIS saying this software--its own software--is hogging resources. The only way to stop it seems ot be to restart the pc.

I'm attaching a screen shot of how it hogs the CPU.  

Any idea how I can prevent this?

Many thanks in advance,

Justin
