OBJ-3.2: Based on the symptoms, it appears that the system may be infected with malware. Therefore, it would be best to attempt to remediate the system by updating the anti-virus, performing a full system scan, and verifying that the web browser and email client’s settings are correct. There is no indication that a recent OS update was performed, so there is no need to reboot into safe mode and roll back that update. Enabling TPM would not help with this issue since TPM is used to store encryption keys for a BitLocker encrypted hard disk. A technician should never send test emails to their personal account as it is considered unprofessional.
