The thing is that, nobody gives a damn about Windows XP users anymore. AT ALL! You are more ancient than the Windows 7 users. This is logical. There is no support for these OS and they are absolete. What do you want? Your system stopped being supported by the end of 2014! Do you want software developers ( crackers included ) to include users that use absolete software? And why do you want such a high end security solution like Kaspersky? Seriously why? Why not use Microsoft Security Essentials? They are perfect for the system you are running. You want something better? Then you have to update your OS. I'm sorry but this is true and somehow i know that you know it. You can google it also. Basically, what i mean is, that you don't need Kaspersky for the system you are running.
