Hi there, no idea what to do? Thanks, Alois. 

You may want to switch to an antivirus program less prone to false positive alerts -- which is what this is.

CompuTrace is a commercial product that is embedded into firmware to help people recover stolen laptops.  Doing that requires it to exhibit some virus-like behavior, such as phoning home, and it can also be used to remotely wipe the system since some companies might want to do that if their laptops are stolen.  But before you can do any of that, you first have to activate your system's CompuTrace instance.  Dell includes the actual application in the firmware, but it doesn't do anything until it's activated.  If you haven't yet activated it, you also have the option of deactivating it, but if you do that you will NEVER be able to reactivate it.  And if you've already activated it, I believe it can never be fully deactivated.
