I can not connect to any antivrus websites. I am trying to download Microsoft Security Essentials and I keep getting an error message that says My computer cannot connect to the microsoft server. I also tried going to the AVG site and received the same error message. I do not know a lot about computers so please be very specific with your advice. Thank you in advance! Oh, and I am using a windows XP operating system and Firefox browser. I dont have access to any other computer at this time, so I am using the infected computer to access this site.
