We have a Windows 7 Pro 64-bit desktop machine running a SEP 12.1.2 64-bit unmanaged client. We have an intermittent problem where a manual scan - either an active scan or a full scan - initiated from the client UI - Scan for Threats - select either the Active Scan or Full Scan icon - completes immediately.
The scan results dialog box reports "scan completed" and "files scanned 0".
Most of the time the scans work fine - the active scan reports 1,000+ files scanned and the full scan reports 80,000+ files scanned. But, when the issue occurs with the scan completing immediately - 0 files scanned - occurs, then manual scans are "stuck", they no longer work. Any subsequent scans complete immediately with 0 files scanned.
We've had this happen 3 times in the last month.
We are getting around this by restoring the client from an image copy.
It's not a rights issue, we are running under an admin account. Also, 99% of the time the scans work so if it was something in policy or user rights the scans wouldn't work at all. We've checked the Knowledge Base and haven't found anything that matches our issue.
Looks like a code defect to us. Has anyone else experienced this?
