In the many years (decades) of IT work I have never had a AV/Malware removal product prompt for a reboot while still in the detection phase of a scan. Generally you have a removal phase after detections are complete. Finally reboots are generally needed to complete the removal. The reboot prompt during the detection phase made me think that something was amiss. Every product I have used generally has 6 phases: Set Options, Detection Scan, Prompt for Action (unless automatic actions are set in Options), Removal (with possible reboot), Verify, and Report Results.
I will gather logs as soon as I can.
