It appears from your screenshot that you have XP with Virtualbox installed. A "WinVerfyTrust" problem is a hardening problem, See Diagnosing VirtualBox Hardening Issues.

If you are running Virtualbox in a hosted online environment, you might have trouble if the hosting company does not provide virtualization technology into the environment you're trying to run Virtualbox in. It's called Nested virtualization and it does not always work.

cant install virtualbox 6 series

Virtualbox 6.x.x requires a 64-bit operating system. If you have 32-bit, then 6.x.x will not install. 5.2.x is the last version that supports 32-bit OS's.

i install virtualbox 6.1 lasted version on my computer with hardware virtualization and install windows 2003 in virtualbox , and then install virtualbox again in vm , not running

OK, so you're trying nested virtualization. This requires special setup, and I haven't got the computer necessary to try and test it myself.

Try web-searching this:
