okay thats fine, Tweaknews. There are others who have returned to avast 4.8, because their system is run better on that version.
Obviously you would prefer to be on v5 if it could be made conducive to the environment in which yr system currently run smooth.
Unfortunately I do not know the answer to this problem. Other than perhaps, the new Beta build 5.0.492 may prove conducive.
I guess that v5 Free AV would be first stop. If works there, likely be the same with Pro and IS.
Just let us know what you can as you go, in yr free time. Sometimes it takes a bit of time to find the ideal environment.
I've been setting up a new computer over last few days, and a couple of things I just cannot seem to get without getting mixed up.
But finally I think I'm okay and system is go. I'll be running AIS on this unit, so upgrade to new Beta build and see how we go.
I know you can't keep do uninstall / reinstall merry go round, but new Beta build might be worth a go, or wait for official release.
