I am a first-time user of a licensed version of Spybot 2-- Search and Destroy + AV 2.4 and am having trouble running a successful system scan. I'm running the scan on a fast Windows 7 machine with several 1.5 terabyte hard disks (though only the system disk C was specified for scanning). I ran the system scan overnight for 8 hours, and in the morning the details window stated that the scan still had 431 minutes to run! The log indicated that a number of files were quarantined. I was, however, able to run a deep scan in just over one hour, and no malware was found. Any advice will be greatly appreciated.
