Get yourself a good firewall, I am using privatefirewall, antivirus is Avast. Download these you won't have security problems, keep your browser up to date. I am actually running on this reply an older system using AMD and the last version of firefox supporting XP. I experimented with an Intel processor system and there was some graphic glitch in a software and the system had some problem, its dead Jim. I am stuck on AMD. If your concernend about updates, MS has done security patches for older systems even tho they have ended support on them. I have a Win7 system, but there are some quirky features I don't like, I will keep it for compatibility issues, but I will keep XP for the same reason and I even have a win98 system for the same reason even a DOS system stuck away. another feature I dont like for Intel processors are the CPU pins, there are not pins, but feathery contacts that are fragile. one wrong move you will ruin them installing them. AMD pins have always been solid pins.
