Hello Mag,
thank you so much for everything. I hit the reset button several times in the hope that everything will be okay again and scanned my PC with avast and malwarebytes. No infections were found.
I came across the link you gave. Thanks for looking it up for me. Indeed the explanation in the link you gave sounds good however there are several forums, where people expressed that the gz file might be a virus. I don’t know it. I wrote to ebay’s customer service and they did not really know what it is. It can be due to a broken link however they could not explain the connection to the download link. They told me to uninstall or to ignore it but I cannot find the gz file anymore. Could you kindly tell me where I can find the SafeZone folder on my PC in safe mode, if it’s not too much trouble for you?
I hope it wasn’t something harmfull and I can shop online as I am used to do without any bad suprises. Thanks a lot for your help. It’s definitely apppreciated.
Have a nice day
