I have downloaded OpenOffice to my sister-in-law's HP mini (I think on 8th February 2014). She ended up with the "*Start.MySearchDial.com <http://Start.MySearchDial.com>"* redirects virus on her machine.
Nothing else has been downloaded onto her machine in recent times so I do not think it can have come from any other source. With hindsight I now recall that the process seemed not to be as simple and straightforward as on previous occasions when I have downloaded OOO. I hope this info will help you be aware of the problem. Graeme Charters
