For those of you who plan to run resource intensive applications such as Adobe Photoshop, for example, or an anti-virus scan my best advice for you for now is to temporarily disable TeaTimer and then reactivate it after the scan if your resources are limited. I do not know if it is a memory leak. I have encountered this issue before when the 1.6.x build was first released, there was a registry tweak to lower the memory usage but I do not know if it would work.

I would advise against downgrading your TeaTimer. I would much rather have the protection it offers and take the extra step to disable it when it is required rather than strip it of it's protection values for more memory.

Do not worry because the 2.0 build (major upgrade) of Spybot-Search&Destroy will resolve the memory issue.
