When the computer is running for a long time without a standby, reboot, or shutdown memory consumption of a (refers to any) can slightly increase.

It's taking that much because TeaTimer is a Resident Shield that actively protects you from malware. I would suggest you reboot and see how it goes. Usually TeaTimer will take up 35-50MB of RAM. Seeing that modern PCs built today have more RAM and resources, 80MB should be nothing.

If this does not help you can disable TeaTimer as follows:
- Go into Spybot - Mode - Advanced Mode - Tools - Resident.
- Uncheck the following: Resident "TeaTimer" (Protection of over-all system settings) Active.
