You need access to the web in order to update. There's no way around it, no matter who's AV or similar pgms. you use. If you have to, manually d/l the update provided they come as a separate packet and transfer that to the AV pgm.. Using a library system or friend's maybe the best way, unless you access to another system. You're in a catch-22 situation. I don't why you don't have access, but if dial-up is possible check into that, cost is pretty low per month.
My Older XP computer Is no longer connected to the internet but is still used mainly for music so I still transfer alot of files using my flash drive. The thing is The Internet Security (CA Anti-Virus and Anti-Spyware which made the coputer really slow) Is about to expire and as It is not connected to the Internet so It was not being updated.
As I said I still transer alot using my USB Key and don't want to risk loosing the computer so I want to Install a free edition but how do I keep It up to date without being connected to the Internet.
