It is always trusted to buy software from the software companies because they always provide you with the things you specify to them and not other third party software in the package. There were number of incidents where people get the software freely or cheap but after loading into the device, they found nothing but bundle of virures, In extreame cases there are software which can easily transmit your computer or devices information to other unwanted entities and because of this there were number of crimes happened. So I would suggest you all to buy it from the trusted websites.
