Hi! I'm using Avast Free that I download last month (August), and on July. The first installation had updating issue, so I reinstall it with newer version (August). But, sadly, it still has the same problem. The problem is: the program can detect that the server has new update (current: 110704-1, latest: 110906-1). But, when I click update button, the progress bar shows no progress. So, I assume the problem is in my windows XP, something to do with service or else. What should I do then?
