Okay, I'm still somewhat new to this whole support forum, so if I need to just start a new topic, let me know. I updated to 1456 and after shutting down/starting up (only have it on when using), it let me log in but went to a black screen with only the pointer. Let it sit for a couple of minutes, restarted several times, no luck. Finally let it sit for as long as it wanted and it finally got through, but am afraid of it doing it again. However, with both this update and the last one (1426, I believe?), my computer's startup is quiet sluggish. First, it takes longer to finish bringing up the gadgets and things, and then after a few minutes of running will freeze for anywhere from 5-20 minutes before behaving itself. Haven't uninstalled it as I got the paid version and don't want to lose it, but would like to know if this is a known issue for avast! and if so, what to do about fixing it.
Also, even with all of the quirks, I will never switch to the other companies. I am quite happy overall. Keep up the good work!
