Will I need to “uninstall” 5.0.677 before installing 5.1? Or, will 5.1 install over 5.0.677? I ask because I have a feeling others have the same question.
You can install over the top but i still prefer a clean install myself.
Hi.
While I believe it preferable to uninstall old versions of anything, with a well-designed upgrade/update of a well-designed product, manually uninstalling the old version should not be necessary - unless specifically required by the new version.
One advantage of not uninstalling first, can be the carrying over of all the custom settings, from the old to the new.

+1…you should remove previous version by removal tools before installing new version 
I just ran it over the existing build. No problems except that it wiped out my system restore points. Which was ok. I just created another one. Haven’t gotten around to figgerin on why that happened but I will.
Is you’re tray icom problem gone? Mine is.
No…!!!

normaly i prefer that too, but after a reinstall all the ruls for the firewall and all other configuration gone?
Is this a question, Hexo…??
If so, the answer is: Yes.

Yes this was a question.
So first i try to update the existing installation. When everythink works fine… i have to do nothing ^^
When something isn´t working, i will do a reinstall of avast.
Exactly…!

Does this mean uninstall then re-install?
No, that means: Reinstall only, if needed.
Usually you don’t need to do that…
