1) Do a search on your PC for ctfmon32.exe. If not present, you are probably ok. If present, report back on its location for more instructions.
2) Try disabling ctfmon.exe, as per my link, and see if it affects your Wacom pad and pen usabilty. Note that those instructions only disable ctfmon.exe- they do not delete it. They are reversible, so you risk nothing by trying.
3) If it turns out that ctfmon.exe is needed, there should be some way to tell TeaTimer to ignore this detection- ky331 could probably tell you more how to do this. If this is not possible, then I would disable TeaTimer in Spybot.
