I intend to install another copy of avast on home comp. It is not connected to internet due to my vital study material, articles, patient data etc. I want to know is it possible for me to update it offline frequently? I came across a large update file (some 30mb) on avast site. But i practise in remote area & work on dial up or cdma 1x connection with very slow speed. It there any better way to solve this problem?
