I ran the FRST scan software as recommended and will post the results here in hopes of getting assistance. Though they run to completion, none of them find any infection. I tried booting to another partition and scanning the Win7 partition using Malwarebytes, SuperAntiSpyware, and ZoneAlarm. I've tried booting to the Win7 partition and scanning the affected partition, but the scans stop prematurely as soon as they detect an infection and a message displays that a reboot is required. I have a multiboot system in which the Windows 7 Pro partition has malware.
