Viber gets flagged as a virus again

“Viber virus” message might suggest that your computer is infected with malware. Recently, Windows Defender and several third party anti-virus tools have flagged the well-known instant messaging app as a virus again. The tool is easily accessible online and functions on Android, iOS, Windows and Mac OS systems.

According to the official website, the application now helps to communicate over 800 million users[1]. Though the software is devised by a Japanese[2] company Rakuten Inc[3], it quickly expanded its network in other countries by obtaining acquisitions and joint ventures.

Similarly to another communications applications, Viber offers free messages and video calls among fellow app users. You can also call to other countries for a low rate.

This utility might seem highly functional and useful, however, recent reports about Viber being labelled as malware on Android devices and on standalone computers alert users.[4] What is more, it seems that the tool has been compromised before as well. Should you remove Viber? Find answers here.

Serving 800 million netizens

If you have been a loyal user of this messaging application, similar reports might simply seem fake. The company has been steadily expanding its network. In 2010, Rakuten bought Linkshare, New York-based utility.

The following year, it launched its utilities designed for Indonesia and Brazil. In 2012, it increased its investments in Pinterest. Viber is also reported to be the official communication platform of FC Barselona. Additionally, the app is compatible with Android, iOs, Mac and Window operating systems. Thus, what did go wrong?

Previous reports about “Viber virus”

On May 2017, Windows users, who have been using Viber on their PCs, might have got astonished by Windows Defender security alerts. The application was labeled as “Viber malware” and a potential security threat. Some of the third party anti-virus utilities recognized the app as a threat as well.

Interestingly, that the app has been already labeled as malware before. Last year users have reported such behavior as well.[5]

However, at that time, it turned out to be a false positive. Users have declared app data on their Android phones which solved the issue. Windows users offered reinstallation often software to fix the problem.

At the moment, the recent reports about Viber virus are still under investigation. It would be a great astonishment if the reports turned out to be true. On the other hand, the cases when well-known utilities get compromised are not rare. The cases of Skype and WhatsApp application perfectly illustrate such tendency.

Additionally, the very privacy policy of the program contains statements which might trigger concerns for more cautious users. According to it, Viber collects the following types of information:

  • Registration and Account Information
  • Social Media Information
  • Activity Information
  • Information from Other Sources
  • Additional Information

As common for instant messaging application, it acquires a vivid sort of personal data if you connect through Facebook, play Viber games, etc. However, the biggest issue is the privacy issue:

We only share your personal information with third-parties outside of Viber, for the purposes listed above, in the following circumstances(…)

Thus, it purely depends on you whether you are fine with such use of personal details. Otherwise, you might want to perform Viber removal. One of the options to eliminate it is to use Reimage or Malwarebytes Anti Malware services or uninstall it manually.

Tips to escape app “impostors”

Due to its increasing popularity, there is a low possibility that you might encounter this app in the form of an optional add-on. Likewise, “Viber hijack” does not exist either. The application is available on its official website. In addition, you can also find Viber as a browser-add-on offered in Chrome web store.

Even though the distribution network does not raise concerns, do not exclude the possibility that crooks might exploit the software for their malicious purposes. If you are about to install Viber, download it from its official website. Once User Account Control notification pops up inquiring you about enabling the app, check whether Rakuten Inc is indicated as an official publisher. Do not download the app which presents “unknown” publisher.
