Spybot S & D - Vista Slow Down

After hours of messing around and backing up files just about ready to format and re-install Vista, after experiencing horrendous performance I realised that Spybot Search And Destroy was to blame.

I have used Spybot alot in the past and always found it fine for detecting adware, spyware etc and having little impact on the machine's performance. Since installing it on my Vista machine recently, my re-boot time went through the roof, to about 15 minutes perhaps 20, even once into vista it would take an age and thrash the disk constantly while trying to even load the sidebar.

If anyone else has Spybot installed and is running Vista 32 bit and is experiencing serious slow down I would recommend giving it the elbow.
