The popular messaging app WhatsApp seems like it will be halting support for a number of old platforms for good. Owners of previous Nokia, iPhone, BlackBerry OS or Android models should now be considering to upgrade their devices as soon as they can.

As the chat app finally hit its seventh year in the biz, they said they wanted to focus their efforts on mobile platforms that the majority will use. "So, by the end of 2016, we will be ending support for WhatsApp Messenger on some mobile platforms," WhatsApp says in a blog post.

"While these mobile devices have been an important part of our story, they don't offer the kind of capabilities we need to expand our app's features in the future," WhatsApp further states.

WhatsApp says that it was a tough decision on their part, but it was done with the intention of providing the users with better ways of communicating with loved ones.

The devices that will no longer have support for WhatsApp include any device that runs Android 2.1 and Android 2.2, Windows Phone 7, iPhone 3GS, and any device that runs iOS 6. The chat app, however, later announced to extend support for Blackberry OS, Blackberry 10, Nokia S40, and Nokia Symbian S60 until June 30 this year.

In related news, WhatsApp users need to be wary of a new phone virus that has been circulating the app. 2 virus files are will try to access into personal details like log-in credentials and passwords of the users. The files are using two well-known organization names, the NDA (National Defence Academy) and NIA (National Investigation Agency).

Please watch out for virus files with the names "NDA-ranked-8th-toughest-College-in-the-world-to-get-into.xls" and "NIA-selection-order-.xls". The virus files will most likely be in an Excel format, however, users should also look out for MS Word or PDF versions.
