It's been exactly a year since I first installed Avast 4.8 and I haven't gotten any notices or anything telling me to update to the newest version or to register again. So I'm wondering whether I should uninstall 4.8 and install the newer one or keep the version I have at the current moment. If I do the latter, will my avast still work since it's been a year? Will I have to re-register it? Also, I've been reading that many people are having problems with the newer version not working well or causing problems...
