Search with Bing “toolbar” is adware which is promoted by the BetterSurf viruses. The adware adds a browser extension to Google Chrome or Mozilla Firefox and a Browser Helper Object to Internet Explorer. When testing this adware we found out that in the newer version this toolbar is added. As default Search engine the “Bing Toolbar” uses your default search engine, which is set to Bing by the adware. Bing from Microsoft is not in any form related to the adware and therefor not responsible in any way to the new “toolbar” in your browser caused by the BetterSurf variation of viruses.
