thank you very much for your question. My name is***** and I will try to help you as quick possible.
I can´t see your previous question right now, but I can tell you that, as long as you haven´t clicked anything or watched someone remote-controlling your PC, no one has access your PC, this is impossible. Maybe you really were just lucky and the problem sorted out itself, but if you want, I can check this for you via a "real" remote-assistance and also bring your Icons back if you wish. I am sending you my offer for a remote-assistance and should you be interested and accept it, I will instruct you how to setup the connection (pretty easy).
Thanks for your patience and best regards,
I see that you have read my answer already. Do you still need my help? If so, please just reply again and I will help you further on to fix your problem. That involves no additional costs for you, you can reply as often as you want until I was able to solve your problem to your satisfaction. If not, please be so kind and submit a positive rating (select 3 to 5 stars at the right top of the screen and click "submit"), so that your question can be closed.
Thank you very much and best regards,
