Malwarebytes does not detect this as a threat…rm

>> Sending Samples to Virus Lab <<

There are two ways of sending samples to the virus lab.

1 Send the sample to virus@avast.com zipped and password protected with the password in email body. It would be better if the e-mail has:

  • False Positive or Undetected Malware as the title or heading

  • If you have a topic in the forums regarding the files you want to submit. It would be helpful to add a link to it in the e-mail body.

2 Open avast! > Maintenance > Virus Chest. From there, right click anywhere inside the Virus Chest and click Add…. Choose the file(s) you want to be submitted then click Open when done. The file(s) you selected will appear on the chest, highlight it then right click and select Submit to Virus Lab

Thank you for your attention, this false positive will be fixed in the next vps update.
