Viber false positive

Recommended Posts


My name is Adi and I am a member of the Reputation and Compliance Team at Viber, hxxp://viber.com/ .

Viber for Windows lets you send free messages and make free calls to other Viber users, on any device and network, in any country!

Recently, our support team received reports from a few Viber users complaining that ESET anti-virus is blocking Viber’s installation file after downloading it and doesn’t let our users to install it. The users simply try to download Viber from our website hxxp://viber.com/  and ESET brings up an alert and deletes the installation file.

Viber is a major brand on the Internet and mobile. Needless to say, our reputation is very important to us. We look forward to hearing back from you that the false positive has been removed from your database as soon as possible.

Thank you for your cooperation,

The installer in question is correctly classified as a potentially unwanted application (PUA) as it doesn't adhere to best practices agreed on by the Antispyware coalition. PUA is an optional detection and a user must explicitly select whether he or she wants to enable it or not. Even with PUA detection enabled, it's possible to exclude particular PUA files from detection.

Since the only channel for disputing PUA detections is samples[at]eset.com, we'll draw this topic to a close.
