Software not working properly and no permission to access disk drives
                                                
                                                
                                                
                                                
                                            
                                                                                I am using Windows XP(SP3).I set upped this operating system 8-10 times last month. Everyone told me to buy antivirus. I bought Kaspersky Internet Security genuine license and installed it after reset the windows. Kaspersky has vanished more than 3,000 virus from my PC.
But problem is still there. All the running programs being stopped after every 15 minutes. I can not open the local disk drives(C,D,E….)It tells me "I don't have permission" to open this folder.
Mozilla Firefox,Google chrome and modem close suddenly without any command. Kaspersky Internet security does not work.
New software don't take installation.
Now I can't understand how to solve this problem. If anyone help me I will be grateful to you.
