These all relate to the Windows Security Center (WSC), have you made any changes in there relating to not notifying you about Windows Updates, Firewall and Antivirus not being enabled/running, etc. ?
These settings should by default be set to notify you if any of them are not running/enabled.
If they set 'not to notify you' as these are it could be a pre-emptive measure for malware to try and disable your security so that the WSC doesn't warn you they aren't running/enabled.
As has been said in this case they aren't deleted or moved to quarantine but the values are set their default setting so you are warned if any of the three are nor running/enabled.
