You don't have to worry. It's normal. The memory usage from TeaTimer can vary from computer to computer. Almost every computer have more than 1gb of ram these days, and the ram is there for a reason - being used. I agree the memory usage is a bit high compared to competing companies, however as I said earlier, the technology has reached a low-level which is pretty "high". With this, I mean the cheapest computers, etc, have more and more ram in-built. Not a single computer should have problem with running Spybot, remember if your pc is running slow, it's most likely a malware infection or a running process which use a lot CPU(not ram).
