Dear Ex_Brit,
Thank you very much for the quick answer. Later I saw, that the Windows System Guards also had the default settings and wasn't not complete disabled. That was only the first item of the eleven 'items' and I haven't seen, that you can switch to the next 'item'. I left the Guards now on the default settings and change nothing, because I'm not a user with great experience, but I want for my laptop the security as good as possible, that's why I ask this question. My internetprovider recommend McAfee as a good product voor security, so I buy McAfee within my provider-package. I'll trust that all is now safe enough and I'm a wise user of the internet, not many downloads, no game-player etc. and if I download than only from 'safe sites' (I also use now 'the McAfeeSiteAdvisor', had never infections or any virus and I hope that my computer remain virusfree.
Thanks and greetings,
Luduina
