Even though Snap.do is a “perfect tool to simplify the web”, when you type, for example, ‘amazon’, first search results provided by Snap.Do are always ads (marked as ‘Ads related to amazon’ – see picture below), unlike Google, for example, that shows you on a hunch amazon.com as a first result:
Popular shopping websites have ad-banners by Snap.Do, and you may not even notice that these ads are not related to the website you trust – a small note ‘By Smartbar’ is almost inconspicuous:
Instead of features’ description in Extensions tab of your browser (Mozilla or IE, for example; Chrome doesn’t allow this toolbar), Snap.Do gives short removal instructions, but this method doesn’t help to remove all the traces of Snap.Do.
Standard Windows directory ‘Program Files’(where new applications are usually installed) doesn’t have a folder called ‘Snap.Do’, but another one called ‘LTD’ that doesn’t seem to be related to Snap.Do at a glimpse (in fact, this it belongs to Snap.Do). Main executable file of Snap.Do is located in a hidden path (C:\Users\USER_NAME\AppData\Local), in a folder called ‘Smartbar’.
