A bug in Windows 10 April 2018 Update rendered some computers completely useless when the upgrade was completed, and a compatibility issue with Avast antivirus was believed to be the culprit.

And while Avast originally said that it found no evidence its antivirus was causing the issues, a company engineer now says that an in-depth analysis of this behavior that was performed in collaboration with Microsoft revealed a problem did exist.

“In cooperation with Microsoft we have identified an element of the latest Windows 10 1803 update that is incompatible with the Avast Behavior Shield, causing the aforementioned update to fail in some instances (related to a timing issue, Internet connectivity issue, etc),” a post on the Avast forums reads.

A fix has already been released to Windows 10 computers running Avast and which haven’t been upgraded to the April 2018 Update just yet, the same post reveals.

“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. The VPS number is 180524-08; all users running this version (or later) should be 100% safe,” the Avast engineer adds.
