Hello,
Suspicious.MLApp is a detection technology designed to detect entirely new malware threats without traditional signatures. This technology is aimed at detecting malicious software that has been intentionally mutated or morphed by attackers.
You can surely create an Exception for the Threat detected by Following the Articles below:
About centralized exceptions for TruScan proactive threat scans
Configuring a Centralized Exceptions Policy
However, Security Response may need to Examine the Original File.
Here are Few steps to Follow:
1) Submit the file to https://submit.symantec.com/false_positive/
and justify why you think that file should be excluded from scanning.
2) I would also suggest you to submit this File to the
https://submit.symantec.com/gold
and get a Tracking number.
3) Till, that time, you could try; Restoring a false positive file detection from the Symantec Endpoint Protection quarantine
4) If the quarantined file cannot be successfully restored on a SEP client with the latest definitions, the best course of action is to open a case with Technical Support.
They will need you to submit the original (not quarantined) file: see if you have it on a CD or known good backup, then submit it from a Linux box, LiveCD, etc (computer not actively running SEP Auto-Protect). Let Technical Support know the tracking number, and they will be able to investigate.
Hope this helps!
