Switch away from Vista... It's a POS of an operating system and even Bill Gates himself admitted it's a flop; I switched one computer to Windows 7 and the difference is definitely noticeable. But also I beg to differ on AVG; try Avast or Comodo free version... I don't know why, but lately I've had clients with AVG that had computers crash/BSOD on older OSes (2 XPs and 1 Vista that was fixed when I uninstalled AVG). Also on one hand, Progman gets fussy about 64-bit usage, but on the other,putting more than 4GB of RAM on a 32-bit computer doesn't do any good... So get a VM and put a virtual copy of 32-bit XP or something on it, or research if a particular software can be made backwards compatible; I know there's like an 8+ page PDF tutorial on making it work but my brief search didn't quite find it.
