No Blue Screen of Death,
But when I installed 5.0 over 4.8 the program would sometimes freeze when visiting the Help menu especially when viewing the Behavior Shields in the new GUI. This happened about 50% of the time, resulting in 5 freeze-ups,
I would often wait for several minutes before opening up the GUI and thought I would try to reproduce the error. Go into the GUI, access Help and you get a 50% chance of a crash and the only solution is to hit the Power Button for rebooting.
I could not uninstall Avast through the Clean Up utility because I was getting some error message. I also did not know the path/file name it wanted. However, a check of the hidden folders, I was looking for anything resembling Avast and did not find it.
At any rate, I did COMPLETELY uninstall 5.0 from Add/Remove Programs and did a reinstall. Got a new license key, UNCHECKED the "Enable advanced graphic interface" or something like that in Basic settings and am just staying out of the Help file because now it seems to be working well. I did submit a response ticket and bug report.
I do like version 5 better than version 4 and can feel the difference in less memory used. I would say DON'T just over-ride version 4. Remove it through Add/Remove programs and than get Version 5 and a new license key.
Everyone should get a fresh install and new license for best results.
Updates have gone great! It's just getting over those little initial installation "humps." I would hope that the next bug fix will take of these things, because once these issues are resolved, this program will be phenomenal!
