The press and Internet users are not kind to Symantec products! We must not stop at these bad reviews. Just try Norton 360 to understand quickly that this is a very successful product unlike Kaspersky Pure, which caused me a multitude of problems never solved. Symantec technical support is excellent and the forum too. I have found no signs of my systems, including an old PC running Vista. Only downside the price a bit high compared to the competition but it is justified by the difference in quality! Amazon and prices are cheaper than Symantec. I therefore strongly recommend this excellent product.
