SymSubmit is used to submit a specific .zip file containing suspected malware to Symantec Security Response. Test on Linux only...,change hard coded fields. Utilize it to "programmatically" submit files. Requires selenium, pyvirtualdisplay, chrome webdriver. If you want to submit silently change it to "Display(visable=0, ....."

symSubmit.py

import time
from pyvirtualdisplay import Display
from selenium import webdriver
from selenium.common.exceptions import TimeoutException
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
display = Display(visible=1,size=(800, 600))
display.start()
driver = webdriver.Chrome()
driver.get("https://submit.symantec.com/websubmit/platinum.cgi")
fname = driver.find_element_by_name("fname")
fname.send_keys("FIRSTNAME")
lname = driver.find_element_by_name("lname")
lname.send_keys("LASTNAME")
cname = driver.find_element_by_name("cname")
cname.send_keys("COMPANYNAME")
email = driver.find_element_by_name("email")
email.send_keys("EMAILADDRESS")
email2 = driver.find_element_by_name("email2")
email2.send_keys("EMAILADDRESS")
supportID = driver.find_element_by_name("pin")
supportID.send_keys("SUPPORTIDNUMBER")
fileupload = driver.find_element_by_name("upfile")
fileupload.send_keys("/somedir/somefile.zip")
submit = driver.find_element_by_xpath("//*[@value='Submit']")
submit.click()
time.sleep(30.0) 
driver.quit()
display.stop()

If you are not a Platinum customer replace the URL in the driver.get field like below:
driver.get("https://submit.symantec.com/websubmit/retail.cgi")

And remove:
supportID = driver.find_element_by_name("pin")
supportID.send_keys("SUPPORTIDNUMBER")
