VIrus?

This is their website. They are billing themselves as a DNS service that protects you from illegitimate websites. Looks legit to me. I wouldn't use it though.

Sendori: Consumer Problem

Just downloaded the app. Norton recognizes as safe. I use Norton dns so I would not use this. It seems to me that a few people installed another product and didn't realize it was bundled with sendori. I highly doubt drive by download.

Pay attention what your clicking when you install and do not do express install and you wont end up with software you were not aware of. Software companies often bundle.
