VT Folder & VT Temp Folder

If sandboxed malware are run from VT folder & VT Temp Folder then they are sandboxed or not?

I watched a test in that sandboxed malware were run from VT Temp Folder & the malware were not sandboxed then, Isn’t this dangerous i.e malware can run automatically from VT Temp Folder & not sandboxed & can infect the system?
