The virus scanner never finds anything, do I need something like this under Windows-10?
Even if the virus scanner does not find anything, you need a protection against threats from the Internet under Windows 10.
Many users complain that the PC is mainly used by the virus scanner. Whether the Defender is disabled you can see in the latest Windows 10 version also in the taskbar! Click on the Defender Shield icon to go directly to Defender Settings. If necessary, re-enable or disable the defender. Also with Kasperski, or Avira are usually the security settings over the To-Tray symbol.
Many users ask me if you are working with the quad-directory explorer disable the virus protection, that's no problem. When you download and install programs, they should be enabled, but when copying data to disk, it can have a very negative impact on the management of files and folders. Because it is always assumed that there is a malicious software.
