The hardening log contains many examples like the above, I've only quoted one example.

What it means is that your PC has been hacked. Possibly by a theme engine or some kind of AV rather than by malware.

There also seems to be some kind of signing error with "\Device\HarddiskVolume5\Windows\System32\SogouTSF.ime".

\Device\HarddiskVolume5\Windows\System32\SogouTSF.ime: None of the 1 path(s) have a trust anchor.: \Device\HarddiskVolume5\Windows\System32\SogouTSF.ime

FAQ: Diagnosing VirtualBox Hardening Issues.

i cannot delete this file. Could you tell me what to do?

Did you search that file name on the Internet? There are a few references - it seems to be harmless.

after searching i still don't know what it is. so what should i do

Read the FAQ. You need to get rid of whatever has resulted in those hacks recorded in the log. There's no way for us to know what you have installed, so we can't give you detailed instructions. If it's pervasive (affects all other apps) and not native to Windows 10, then it's a candidate for removal.
