I bought Norton antivirus 2010 in HK, and the program prompted me to update it to Norton 2011 in UK. Since then I can only do liveupdate in the UK, but once I get back to HK, liveupdate doesn't work. Admittedly I use a proxy (as a program, i.e. Squid) while in the UK, but I changed the relevant proxy settings through misc settings in Norton. Still, liveupdate doesn't work at all in Hong Kong. I cannot even get through the first step.
