Key notes
What can be said about Microsoft’s antivirus solution? Well, even though it’s not as popular as other similar software out there, it is stillranked pretty high, efficiency-wise.
There still are a lot of people that rely on Defender for protection and it seems to be pretty stable. At least, it seemed to, until Microsoft released the latest Windows 11 Beta build.
Things going haywire isn’t something new on the tech giant’s plate, but having issues with the one software that is supposed to keep you safe isn’t something to take lightly.
Many users that have been actively testingbuild 22581arereporting severe video playback delaysthat are caused by the antivirus.
MKV files seem to be the victims, but other video container formats may also be affected, as ISOs are apparently also facing this delayed execution problem.
This caught many off-guard, as this issue isn’t listed among the known problems for the build which means it probably went undetected during testing.
However, not all is lost, as with every problem, there is bound to be a solution, even if we are talking about a temporary one, for the time being.
A simple workaround for this issue is disabling theCheck apps and filesoption under SmartScreen settings.
Users trying this were able to resolve the issue. But before proceeding to apply this workaround, make sure the file type is actually trustworthy.
