Avast and Microsoft determined that the Avast Behavior Shield is what’s causing the incompatibility with the April 2018 Update.
Well, we can now report some good news for those that use Avast and want to get the Windows 10 April 2018 Update, or those that previously installed the update (before Microsoft blocked it) and now find themselves with an unusable computer.
Avast and Microsoft determined that the Avast Behavior Shield is what’s causing the incompatibility with the April 2018 Update. „Luckily, we have found a way to prevent the problem and are now automatically pushing a VPS update to all customers which makes sure that the problem doesn’t happen,“ wrote Avast global moderator Vlk. „The VPS number is 180524-08; all users running this version (or later) should be 100% safe.“
For people that have not yet upgraded to the Windows 10 April 2018 Update, the above software patch will allow you to upgrade without issue.
For those that have a non-functional system due to uses the older, incompatible version of Avast antivirus software, you’ll need grab an 8GB (or larger) USB thumb drive, find a Windows computer that is actually working and follow these instructions:
The above steps should [hopefully] get your borked system back up and running with no loss of data. We should mention that Avast is seemingly deflecting some of the blame away from itself with this incompatibility, as it says that it only affects a „small subset“ of users and that is an issue that is also affecting other software — not that this is any consolation to those that have been sidelined as a result.
