I know, this is a mac forum but we have all experienced working with Pc's and many of us still work with them. So, my girl has a Sony Vaio vpccw21fx and it has not even been a year since she bought it and she got a virus two times and her hard drive failed so after a grueling experience with costumer service having to wait nearly two week for her new HD to be shipped to her, she has installed the new HD and reinstalling all the disks that Sony sent her, 4 disk!!!!! Originally, the machine did not come with any recovery disk, after her HD went bad, then Sony sends her the four disks. What would be your advice to her in regards to getting the best out of her machine? I have heard that the best thing to do is a clean install of Windows 7 but what is she to do with all these disks? I feel like Sony is loading a bunch of crap into her machine. In regards to security, should she stay with Microsoft Security Essentials or is there something better out there?
