I installed the new SEP 12 Beta as an unmanaged client. I ran a full scan and it found numerous files it considers malicious. However, when clicking on a file within the results for Risk Details, I found that the Risk Details is sometimes inaccurate. For example, I got numerous "Suspicious.Cloud.2". Most had an action of "Restart Required - Quarantined". Double clicking any of those came up with the same file size and hash even though they were for unrelated files. Corrective action all had mention of Removing QBCFMonitorService (note, the hash that came up for all was for this file).
On this note, I should mention QBCFMonitorService is a trustworthy file from Intuit Quickbooks, so I do not know why Symantec found this false positive.
