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
