I discontinued using Scheduled Scan since it scans all local drives - which I don't want. Therefore I switched to Custom Scan and ticked as the Default Locations to Scan: C:, D:, E: (all local hard drives). Unfortunately the scan continues with F: and I: (also local hard drives), which are copies of D: and E:. I don't want that to happen: it proglongs the scan unnecessarily. Why doesn't it behave as I expect it to do? Is there a way to get it to ignore F: and I: ?
I just tested that on mine as I have 6 partitions holding 4 different operating systems so it's easy to pick and choose. I chose C: only and it scanned C: only using the Quick Scan and Let Me Choose options.
Did you uncheck the items at the top as in the attached thumbnail? (Click to enlarge).
Incidentally I hadn't scanned in a while and to my chagrin it detected a customization file from my new PC maker as a trojan....LOL, Well, I'll deal with that later.
There must be something seriously wrong: I did as you suggested and tried Technical Support Chat. It requested me to run MVT. I did. It produces an exception (Exception Processing Message c0000013 Parameters 75b0bf7c 4 75b0bf7c 75b0bf7c) and never ends while checking the registry. I had to cancel. I cannot continue the TSC unless the MTV has ended.
