how does 'Eliminates traces of online activity' feature work

Hi Genovezos
 
What you are referring to is the System Optimizer feature which is particular to the COmplete & Gamer versions. It can be found either by (i) clicking on the 'Utilities' tab which will reveal an option label 'Optimize Now'; clicking that will launch the Optimizer running with the default settings as to what to clear) or (ii) by clicking on the gear/cog symbol to the right of the 'Utilities' tab and then on the 'Optimizer tab revealed in the next panel displayed; this allows you to run the Optimizer also and gives you some basic stats on what the Optimizer as cleared out in previous runs, etc..
 
Essentially, the Optimizer is a cleaner, similar to CCleaner but without the range or the configuration features of the latter, but nevertheless I have found it to be safe, reliable and useful for a quick'spring clean' of ones system.
 
You can get all the information about it including how you customise what it cleans by taking a look at the online help (HERE).
 
If you have any further questions then please post back and we will be pleased to answer them for you. :D
