We're at 5 1/2 hours and still not finished. 924,000+ items scanned. I had had the trial version of Malwarebytes Anti-Exploit on for the first 1 1/2 hours of the Defender scan and I turned it off because I thought that might be slowing things.

This is on a Dell Inspiron Mini netbook. Not a huge hard drive here. The RAM has been upgraded from 1Gb to 2Gb, so I don't think that is the problem.

Is this normal? My ESET smart security takes a lot less time and I'm sure it scans a lot more items.
