Several days ago something happened to my machine. From a certain day on the file dialogue component from any application are very slow and take minutes to open. It is even slow in the feedback hub, from which I reported the problem. I deleted some updates and installed them again afterwards, but nothing helped. It is either a problem of the base system to which the user has no access or it is a virus/trojan which has invaded. [I have got 3 drives, a native C: connected via SATA, a drive D: connected via USB and a drive Z: connected v ia SMB and port 445.]
Does anyone know how to fence the enemy in?
