Downloaded AVAST Free Home edition. Installed okay. Can't automatically nor manually update definitions nor program. I use this program on a primary system but my hard drive went bad & that's in shop for upgrades. Now using secondary "bastardized" Systemax, 32 bit, 256 RAM, Windows ME 4.90.3000, Authentic AMD Athlon processor. Cable connection, web safe router. Had trouble installing T'bird but finally got that. Can't install F'fox! Help with the AVAST updating please??? Thanks!
