On the Symantec site, you can not search malwares by its hash, as for now. I made two scripts to help you, if there is a need to check a lot of hashes.
You will need a free VirusTotal account, to use them. From you profile, get your Public API Key (My API Key menu entry), and copy it into the scripts to the marked area in the scripts.
In HashList.txt, one hash (MD5, SHA1, SHA256) per line, you can list the hashes to check. The example contains the EICAR test hash.
VirusTotal-ReScanHash.ps1 will initiate the recheck of the sample with the latest definitions, this can come in handy, with relatively new potential malware, when the before-latest definition could not, but the latest might detect it. It is recommended to run this before generating a report with the other script VirusTotal-GetReport.ps1. This one will check, by its hash, if SEP can detect it or not, according to its VirusTotal detection, and also outputs the name, by it is detected. Output is in SEP_detection.txt.
Notes:
- Unfortunately, Public API access to VirusTotal is limited to 4/minutes, so there is a 26 second sleep between requests (if you have a private API key, feel free to remove the Sleeps). But for most cases (for me surely), it is faster then going manual, even with this limitation.
- The initiated rescan might take a little time to finish!
