I tried shutting down the Shield Control, and that didn't work either. Please let me know what I can do to correct this problem. Postscript 2: I also ran AvastClean utility in Windows Safe Mode as Avast recommends (and, because there was no longer an Avast folder to point to with the utility, I reinstalled AvastAntivirusFree and ran the utility in Safe Mode again and allegedly removed all of Avast), but Windows 8 again will not update to 8.1, continuing to claim that Avast still needs to be uninstalled.

I tried downloading Windows 8.1 again and, during the compatibility test, it came up saying again that I couldn't complete the 8.1 update until I uninstall Avast which, as I said, is already uninstalled. Postscript 1: After writing and posting this request for assistance, I took a chance and deleted all of the keys referencing Avast from the Windows 8 Registry and rebooting, but that still hasn't corrected the problem. Does anybody have any idea how I resolve this problem so that the 8.1 update will recognize that Avast is already uninstalled and complete the Windows 8.1 update? Surely others have run into similar problems? Thank you in advance if you can help. Now Avast is the only one that Windows 8.1 update says that I need to uninstall.

I dug through Windows 8 and deleted all references to Avast, including folders, that I could get to or could find (I didn't mess with the registry because it's too risky and I never mess with it), which worked for other products that the 8.1 update required that I uninstall but I couldn't otherwise uninstall without deleting the folders, or where the uninstall(s) didn't work. I tried reinstalling Avast and then completely uninstalling it again, but that didn't help. Hi, when I start the Windows 8.1 update it keeps telling me that I need to uninstall Avast antivirus software after I have already completely uninstalled it.

Do i need ccleaner for windows 8.1
