The internet and other magazines presented a good review for software doctor. All the reviews of software doctor are only good, and nothing of bad. Because there is nothing bad in the software in general software would have the draw backs while installing for old version and new version. The software doctor has no problem in any window. It works with even windows two thousand and seven there are only a few software goes with windows two thousand seven. The customers would feel regret just because after their purchase of a software is not suitable for their costly window. The software doctor created to work with the old version and for the new version s of windows. The software would have other difficulties that a spyware would avoid only spy virus and it would not work as antivirus software most of the time. The customer need to purchase one antivirus software and plus spyware. But when customers buy software doctor they would be able to enjoy the both advantage in single software which is not expensive. The software cost only thirty four dollars, and the company offers for three personal computers. After our purchase we would feel to review good report for this product.
