False Positive For AntiVirus - Email Sender

Occasionally, your anti-virus software may incorrectly flag Email Sender as containing a virus. This is a false positive and happens for the following reasons:

  • Most anti-virus software looks for patterns in a software package instead of running it. If the pattern of legitimate software matches an entry in its database, it flags it as malicious. This often results in false positives.
  • Email Sender is packaged as an EXE, allowing users to run it without installing it on any machine. Browsers often warn users if they download a program from the Internet and try to run it.

Confirming Email Sender is Safe

Synametrics Technologies, Inc. guarantees that any software you download from our site is free of malicious code. Use the following steps to confirm the downloaded files have not been tempered somewhere in the middle:

  • We often publish the MD5 Hash for the final file. You can confirm the authenticity of the downloaded file by matching this hash on your end.
  • We digitally sign every product. On Windows, you can check this digital signature by clicking the right mouse button, selecting the "Properties" item, and finally clicking the Digital Signatures tab, as shown below.

Verifying Digital Signature of EmailSender.jar

If you downloaded EmailSender.jar, instead of the EXE file, use the following method to verify the digital signature: 
jarsigner -verify -verbose EmailSender.jar
You should see a line towards the end that says:

Signed by "CN=SYNAMETRICS TECHNOLOGIES, O=SYNAMETRICS TECHNOLOGIES, ST=New Jersey, C=US"
