A question or two, if I may. TeaTimer runs heavy relative to other apps, top of the list in the picture, about 123,272 k. SpywareGuard does also, sgmain.exe plus sgbhp.exe, total of 12,712 k. That picture is generated by process explorer from sysinternals.

Process Monitor, also by sysinternals, shows that both apps are very busily monitoring the registry.
The reason for the question is mps69_1999's original post. It is asking sort of "What to keep and what to throw away" if I read it right. These applications don't slow this machine down enough to notice, but they seem to make a noticeable difference on slower computers, owned by relatives and friends.
The frequency of updates issue doesn't seem to matter much for TeaTimer and SpywareGuard (when ya got it right, don't fix it, eh?), although it might for Spybots on demand scanner, right?
In the past, both TeaTimer and SpywareGuard have caught baddies which got past everything else, and locked this system up until I decided what to allow or deny. Made the wrong call on more than one occasion. ![:P]()
So the questions are, do they duplicate each others' functions? And, if so, which to lose?
Also, a suggestion, use some sort of virtualization software, Sandboxie, plus Returnil or Powershadow, so that if all else fails and you have to restart, any damage is gone. (so far, fingers crossed)
