I seem to be having the same problem as other people.I have just updated my Zone Alarm to the latest version (an paid a fair bit of money for the privelage) and the anti virus will not update.
I know it is downloading something because the blocks move and I can see the activity but after a few minutes it comes up with an error saying it can't update. I have followed all the advice given to the others and cleaned and re-installed a number of times. I have removed all possible conflicting software with no result other than to make me stay up real late (2am) trying to fix this. I have even tried going back to an older version of ZA and trying that and I get the same result.
Nothing has changed on the machine apart from the fact that I now contact via a Wifi router rather than hub direct - but I can't see that being an issue.
Anyone got any bright ideas as it seem not just to effect me but others as well but as I have just paid out for 2 years of updates I am not really willing to let this go like the others.
