Some technical support scammers are looking for particular installed programs. For example they look for ‘Oracle VM VirtualBox Guest Additions´.
In this way they can determine if they are connected to a VM. So removing that from the uninstall list showed by Control Panel > Add/Remove Programs is not a bad idea.
It´s easy …

• hold <Windowskey> + <R>
• type regedit and hit <ENTER>
• locate HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall
• in the left pane right click on the key and choose delete
